I am trying ot call my summary data from my summarytoolstripmenu, to the Public Class Form2 Private Sub FormSummary_Activated(ByVal sender As Object, ByVal e As System.EventArgs)'Display summary information
End Sub Private Sub ButtonOk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonOk.Click
'Hide the form
Me.Hide()
End Sub
End Class
But for some reason I must be missing something in the text because it still pops up my messagebox instead of the seperate form i intend to call up
I'm working on a base class right now, here's a basic rundown of it:[code]The problem is, in the Public Class bar example, some classes may implement MyInterface, and others don't. What I'd like to be able to do is have the sub New() in the structure in the base class "Foo" be able to tell if the class calling it (either the Base class, or the child class) implements MyInterface or not.
I really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:- m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.
I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _ lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
I am designing a backup/restore utility for work.atm i have been able to populate field for PC name, IP address, MAC address, number of printers installed on the PC but i am wondering is it possble to get all the printer information 'with the click of a button' to print all information like the prnmngr.vbs script down.I am able to run a batch file but i wanna get it to go from that app or even embed to batch file to the app and run it form there .
I have an MDI container with a ToolStrip. I ran into a naming issue with images/icons. I removed the lines of code referring to the image of the buttons in the MDIForm.Designer.VB file. Then, in the actual designer, I imported the image file as a project resource and added this image to each button.
When I view the MDI form in the designer, the buttons appear normally, but when I run the app, the buttons are not there!
Should i have not edited the designer.vb file directly? Can this be fixed without recreating each button?
I'm making a little webbrowser just for the heck of it, And i want to know if you can use a toolstrip for a bookmarks bar. I have it laid out, I just would need the code to make the buttons work.
Is there another way to add a Context Menu to a ToolStrip other than using the MouseDown Event? I want to use it to let people select to either show text labels on buttons in the ToolStrip or turn them off.
I would like to make an example to insert a DateTimePicker control to a ToolStrip, but not like the examples I found on the forum, otherwise, so that when you want to add controls to the ToolStrip, within TexBox controls, splitButton, Label, ComboBox, etc. also ....., DateTimePicker control appears as a possible control to add,
I created a toolstrip with some buttons. I have a form with some objects (like textbox,checkbox,button etc.) and when i get the focus on last item,when i finish to compile i need with tab on keyboard to get focus on save button on the toolstrip.
I look for way of easy change ToolStrip colour from horribel blue to any other color. I try make gradient image in memory for set BackgroundImage property but cannot know way to make image gradient for memory.
i have a question about toolstrip button.example: i have 20 form consisting MasterItem,MasterPart,MasterProduct,etc.all form have 6 button:New,Edit,Save,Delete,Cancel,Exit Button in toolstrip.the problem is : if i have a few change in toolstrip,I must change all 20 form. that's waste my energy and time.
i want to create 1 toolstrip but can use by 20 form. so if i have change,i don't need change 20 toolstrip. when using PHP,i am using include "menu.php".and this file "menu.php" can use by anyform in PHP. so if i change "menu.php",that's effect to any file using "menu.php"
i need to display query data on a CheckedListBox and this is not a problem, but also i need to add this checked listbox to my toolstrip and this is when my problem starts, is there a way o doing this easy or do you have some sample code?
I need to remove all the buttons in my toolstrip so they can then be repopulated. But I have no idea how to remove them. I tried using a For statement:
For Each ToolStripButton In Mainwindow.FavouritesBar.Items() Mainwindow.FavouritesBar.Items().RemoveAt(Mainwindow.FavouritesBar.Items().Count - 1) Next MainWindow is the name of the form that FavouritesBar (The ToolStrip) belongs to.
I am calling this from another form, but I keep getting a "Collection was modified; enumeration operation may not execute." exception.
how can I stretch my toolstrip buttons? The size of my form is 300 x 250
I only have 5 toolstrip buttons, so the buttons only fill up half of my form. How can I make it so that the buttons stretch to the size of my form? So, that I can fill up the whole toolstrip?
I used a toolstrip and set an image for it's button but I removed this image from resource in solution explorer and all toolstrip is gone. I removed images that have !sign in resource tab of properties but toolstrip is not visible in design view. how it returns? before I had typed tooltip instead toolstrip and I edit it now.
I do have a form with a ToolStrip and some other controls on it. I use this form in other projects as kind of base form, which means that the other forms inherit from this form.
My problem: In the designer I can not change any properties (property window is read-only) of the Toostrip or add new buttons on it. All changes I have to do must be done in code instead of using the designer. ToolStrip-modifier property is set to Public.
i use some code for toolstrip(indentical standerd item)in vb.net 2008. But it give me error Private Sub InitializeComponent() has multiple definations with identical signatures and one another error which is Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)has multiple definations with identical signatures 1: Private Sub InitializeComponent()2: Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
