Manipluating Multiple Controls On A Form [VS2008]?
Jul 18, 2009
Im currently working on a project using VS2008. One of the features of this applications is to enable the user to change the theme either buy selecting preset ones or defining there own. The themes used in this application are not the default windows ones. I basically created my own window, titlebar etc... with the use of panels and removed teh windows form borders. So its basically coloring the controls on the form. At the moment the theme information is stored in a "txt" file and when the application loads, it applies the theme to the current form. However, there is more than 1 form within this application. I dont want to write many lines of code to apply certain design/appearance properties to every control in the form. So is there a way to apply settings to a group of controls?
EG: Make all textboxes BackColor Blue
My application also has widgets. All widgets are panels with their names prefixed as "Pnl_WIDGET". Is there also a way to set propeties to all panles with the name beginning with "Pnl_WIDGET"?
When I click a cell or a row in a datagridview I want to be able to open a new form with several textboxes and comboboxes in it and to be able to edit the selected row. The only thing I managed to do so far, was to fill a texbox from the form with the info from the sellected cell using the following code.
I have eight NumericUpDown controls in my form, I call them NumericUpDown_1 thru NumericUpdown 8. I first noticed when I set a breakpoint in say NumericUpDown_1 routine and have code inside this routine to manipulate say NumericUpdown_6's value, the code would immediate jump to NumericUpdown_6 routine because the value changed. This makes sense since the handler fires due to the default handler - numericUpDown_valuechanges. But I do not want this to happen so I removed the handlers for all NumericUpdownX routines, one thru eight and instead I use "addhandler" and "removehandler" statements inside the individual routines to "mask off" this problem every time I change a numericUpDown.Value that is not in it's own routine.
My problem is this does not work. What I found is if I use removehandler numericUPDown_x.valuechange addressof numericUpdown_valuechange statement the coding would work however when I'm done in that routine I follow up with addhandler numericUpDown... statement and I'm back to the same problem. A different numericUpDown routine will fire because I changed it's value in another routine but I had the handler removed before I changed it's value so I don't understand. It's almost like it remembered that it's value changed as soon as I turned back on the handler using addhandler. I'm working with Visual Basic 2010.
I'm trying to iterate through a group of ComboBoxes and set a property using a concatenated string & variable to represent the name of the control. However, I can't get the instance of the form to recognize the (String & Integer_Variable) as one of its controls -- and so it doesn't recognize any of the appropriate properties or subroutines as members of the System.Windows.Forms.Control.Is there a cleaner way to do this?
For myTempCount = 1 To 6 If tempValue < Me.("ComboBox" & myTempCount).Items.Count Then ComboBox.SelectedIndex = tempValue 'appears to work -- how?[code].....
This code was originally VBA / VB6, which I put through ArtinSoft's Visual Basic Upgrade Companion (VBUC). FWIW, I'm using Microsoft Visual Basic 2010 Express.
How would I go about doing multiple layers on a form?Say the first layer contains a command button that when its click, it changes to the second layer hiding the command button and showing the controls on the second layer?
Still using VS 2005. My concept is to use the same form space to display different "pages", like a "wizard" where you click the [Next] button, and the current UI disappears and a new UI appears. I want to "turn off" multiple controls and "turn on" multiple other controls. Example code: -
At design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime. I need to be able to create image maps based on textual copies of medical claim forms that are generated from different systems and the ability to create dynamic label controls and move a single or multiple controls and resize is required. How does MS do this in the IDE?
I have a form that I will be using to keep track of data for computers I build and will eventually link into a database for configuration management, but for right now I'm just trying to get the basic form layout done and functional. I need this for to be customized for each job I do, that means I can have multiple computers, PC card, peripheral equipment, etc. So with that said basically what I have done is created a user control for each separate item that I want to add (i.e. computer, PC card, etc) that has all the fields and functions I require. When I want to add another computer I just add a tab and place my "computer" user control on it, no big deal...
My issue is when I want to add my "PC card" user control to that "computer" user control. What I am trying to do is to add the first user control(PC Card Info) I created under a button called "Add New PC Card" (which is part of the "computer" user control.)and that part works! What I want to do is keep added as many "pc card"user controls as I need and basically keep appending them under the last control on the bottom of the page (which is the "pc card" user control, that is a groupbox with a few drop down boxes and text boxes in it.)with a little spacing between them. The biggest problem I am having is when I add the first "PC Card" user control, it works.. but when I try to add another one and search the current page for all user controls under a certain point or with a specific name, I don't get any results.
I think I'm on the right track with the following code but I am running into 2 things I can't do that are critical to my needs. 1: I need to define the text of the user control I just added so I can uniquely identify it, so If I need to remove it I can and will also play a role later( I thought if there was some way in code to make my control # a variable that may work) 2: I need to know what to look for since I have a count that represents how many of that particular control exist on my form, that way I can name them properly, this will also allow me a method to delete the user control if desired.
Dim pccard As New PC_Card Dim x As Integer Dim name As String
How may I correctly assign textboxes, dropdownlists & labels to appropriate fields, on successful retrieval of records via a SQL statement? I have 4 tables & therefore, the assigned data don't match the controls. (VS2008)
I have a method that saves form controls data to a text file, including its text. IF a label has multiple lines, this breaks the text file writing multiple lines to it.I was instructed to simply ignore multiple-line labels and don't include it in the file, but I don't know how to check whether or not a label has can multiple lines or not so I can throw in an 'if' statement.
Using the below code, allows me to filter a data (from the same table) in a database using checkboxes & their Tag property.
Public Class Form1 Private checkBoxes As CheckBox() Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
Since certain movies can belong to multiple genres & vise versa, I'm trying to alter the code listed above to filter all movies belonging to a certain genre using the GenreID found in the joint table.
Is this possible or do I need to go about this in a different way?
I wanted to know if anyone could tell me how to access the Click_event.I have a boarderles form with a panel control which has the Dock property set to fill and on the panel I have placed a Label also with the Dock property set to fill. I also have a timer running.How can I get code to execute in the Label1 click event.I've tried doing it by using the generic Click_event and also with two variations of the Click_event Handles parameters
'Alternativ 1: Private Sub Form1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:
#Region "Proxy" Public Structure Struct_INTERNET_PROXY_INFO Public dwAccessType As Integer Public proxy As IntPtr
[code]....
Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.
I have a project in VS2008.Net3.5 with a Module1, form1 and form2.
[Code]...
Question: At the beginning I am opening form1 from sub Main(). Now from the menu I am openning form2. In form2 I am clicking Done button to hide form2 and go back to form1. It works fine in the 1st trial. Keeping form1 open for the 2nd time, I opened form2 from the menu. Now when I Click the Done button 2nd time it just hides up everything. Form1 does not show UP. It just exits the whole application. But in my btnDone event, I have frm1.show().
I have an application (hyperterminal) that I have loaded inside of a form. I know how to use it when the application is open outside of the form but how do I use appactivate to interact with it inside the form?
I just moved from VS2005 to 2008. All seemed fine until I started playing with locally cached data sources. After that I started getting this problem and now I get it even when starting a new project. I start a new project and debug, Form1 shows and all is well. If I add a combobox to the form and debug the form immediately closes. It doesn't seem to do it for other controls.
I have a project in VS2008.Net3.5. I have 3 forms in total. The Sub Main() in Module1 first calls the Form1. Then Clicking Button1_Click event in Form1 opens up Form2. In Form2 I have a text box that I will fill out from Form3. But when I am Clicking Button1_Click event in Form1, it can't keep Form2 open but it opens up Form3 directly. I dont want this. I want to open Form2. In Form2 I will press the textbox and then we have Form3 open. But this is not working.==============
Module Module1 Public frm1 As Form1 Public Sub Main()
[Code]....
The Sub Main() in Module1 first calls the Form1. Then Clicking Button1_Click event in Form1 opens up Form2. In Form2 I have a text box that I will fill out from Form3. But when I am Clicking Button1_Click event in Form1, it can't keep Form2 open but it opens up Form3 directly. I dont want this. I want to open Form2. In Form2 I will press the textbox and then we have Form3 open. But this is not working.
I knew that in Form2 the first focus is going to the textbox and it then opening the Form3 for the GotFocus method. How can I move the focus to other control in Form2 instead of the default focus to my textbox. Or is there other event method other than GotFocus?
im currently designing a student application form in my VS2008 Project.Theres a lot of information that the end user needs to insert for eg, Applicants Info, Parenta Info, Medical history etc What i want is some advice on how i can design this? At the moment i have too many textboxes and comboboxes for the information that needs to be provided and im losing space on the application form. Do i split the form into different parts using tabs, ie tab for student, tab for parent etc or is there a better way?
I am trying to create a basic windows form on VS2008. I dont see intializecomponent() method in my form. Also, I added a few controls on to the forms and set few properties for those controls on design view. Where is that code getting stored?? it isnt on the code behind file.
I know thr is no html code behind file for window forms?? also, where is intializecomponent method. Please help me out. I have been trying to find this out for such a long time now.
I have 2 modules and 2 forms. In the module1, I initiated the form classes and also here I have my public appexit() method.In module2, I have another class(in the form of a keyboard done by code). Form2 use this class as its control.I have:
form1_closing() mybase.close() )
[code]....
Now when I call appexit() in my module1 from form1, I can see that the debug is going into form1_closing but when it goes inside form2_closing, it crashing the application here.I am developing mobile device application in Vs2008.Net3.5.
How can I add controls to a form in code and set the properties of the controls using the With statement?Also I would like to know how to add a container control and then add a control to that container.
I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
I have the following code which is used by 7 comboboxes, the only difference is the combobox1 to 7 and the DataGridView5 to 11. In VB6 I would have used arrays, is there any way to write the code once or do I have 7 ComboBox1_SelectedIndexChanged subs.
My application has a TabControl which has 5 tab pages. Each page represents a "department" and each department has to run this software. So when the user opens the application, they navigate to their department's page.
The software runs a serious of automated and manual tests. The tests are customized for each department. But I need to update the UI during each section of the test.
On the main tab, there is one panel that has 17 PictureBoxes. Each PictureBox represents one test. The PictureBox can either represent a test in progress, a test passed, or a test failed.
All of the tests are in their own code files, for the most part. And in the main form is when I call the tests and update the UI from a single method.
The issue I'm having is how to update the PictureBoxes without creating a bunch of redundant code.
When the test runs, I update the first PictureBox with "in progress", then when it completes, it's update again with pass or fail. So for a single test, I could need to place the UI update in several places, within the same code block, for planning out all the possible conditions.[code]...
I have a module level sub that I use to clear text fields etc on my forms:
CODE:
The problem I have is in the last few lines of code as I'm not really sure how to access the text boxes contained within the tab controls (of which there are many tabs and many text boxes).
This is the closest I've got but I am getting an "option strict on disallows late binding" error on the tabCtl in the following line.
AM trying trap specific events for some controls on a form. i tried this, but its not fireing the events
[Code]...
EDIT I found out that am placing the control in multiple controls, on the form is a panel, inside the panel is different groupbox, these group boxes have the controls am trying to trap their events
Recently i worked on a VB. I have to know how can create controls Dynamically on the run time and how can access these controls on the runtime??
Ex: I want to Create 10 checkboxes at runtime. After creating Checkboxes Dynamically how can i access these Checkboxes?? like i create Checkbox Called "chkAll" , If i check "ChkAll" checkbox then all Dynamic Checkboxes should be Check otherwise UnCheck?
In my project, I am trying to change the visible property of my various pictureboxes using a for - next statement. My aim is to get the value of my numericupdown1 control and use this number to make the pictureboxes visible. For example, if this number is 8, the picturebox1, picturebox2, .......8 will be visible. Here is the code I wrote:
