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.

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

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.

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]...
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:

This sounds simple and I'm sure it is. I have a form with textboxes and combo boxes within a tabview that has 8 tabs. All the data is loaded from a database. The user has the ability to update these controls and then update the record in the database. Is there a way that I can check an entire tab view or group of controls for value change other than using an if statement to cycle through each control? Something to the effect of If TabControl changed, then execute...

View 3 RepliesHas anyone tried using controls from different sources into their application that uses winforms? Will these combination of controls work together?
View 3 RepliesI 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 have a set of controls and code behind them that I'd like to reuse on multiple forms. How can I do this? I know of reusing code via modules, but I'm not sure how I can add the same controls and their underlying code. If I achieve this, will changing data on one form affect the values of another form when they're both open? For example...
Cbox1's selected item affects the choices within Cbox2, and Cbox2's selected item affects the choices within Cbox3 (and so on).
So if I do something on Form1's Cbox1 and it changes Form1's Cbox2, will it NOT change Form2's Cbox2?

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?

I've been working on a project for a class for the last few days. Here is my current issue, I have created a form where I have multiple buttons representing different t-shirt with different prices. So hypothetically, if the end user were to click on the button that is assigned to red size small there would be an extra $2.00 (on top of the $5 fee of any other t-shirt), I know how to code for the calculation of one item, but I'm not certain how to add say a small red shirt, and a large pink shirt, and have the two items calculate correctly.

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"?
I've created a news ticker control, which reads from RSS feeds and scrolls the text Horizontally. The plan is to have 3 of these on my Windows form, which will each display their own information.
The control is created as a label, which is populated with the text, and then scrolls right to left using a timer, once the label gets to the end of the text, and disappears of the left side, the rss is re-read, and then the cycle resumes. The problem is that with multiple copies of this controls on my form, once one gets to the end of it's run, all three freeze while the rss is reread, rather than just the control that needs to do it.
Is there a way to run each of these controls independently (threading?)? Or is there a glitch in my code causing this? (below - some elements not included, but it should be fairly obvious what is happening!)

I have a program that allows the user to add steps to a process (tabpages in a control). All tabpages are generated on the fly by duplicating a "template" tabpage and consequently have the same control names such as textboxStepDesc. Here is the hierarchy of the controls to get to textboxStepDesc. Both TabPage1 and TabPage2 are in TabControl1
TabPage1
Panel1
textboxStepDesc
other fields
[code]....
Since textboxStepDesc exists in Panel1 in both TabPage1 and TabPage2, how do I specify that I want to retrieve the value of textboxStepDesc.text on tabpage2 vs. textboxStepDesc.text on tabpage1?
I have a project where I need to add TabPages to a TabControl. I have a Panel with 10 checkboxes on it and I want to replicate that onto each TabPage as it is added.What I get is it is added to the first page, then when I add a second tabpage, the panel is moved there and not replicationed even though I used the (Add) method.
