I have a WinForm in a vb.net application. It has between 4 and 7 multiline textboxes. I want to be able to copy and paste information into or out of those textboxes but it appears to be impossible. There is no right-click cut copy or paste available and the keyboard shortcuts do not work either.
The properties of all textboxes are enabled, visible and have shortcuts enabled
Can anyone help please?
Create first a ContextMenuStrip.
Add new menuitem: 'Paste', set the menuItem's ShortcutKeys property to CTRL+V.
Set the (Rich)Textbox -> ContextMenuStrip property to created menu control.
Handle the 'Paste' menuitem click event.
Try the result.
Its seems to be a strange problem.Make sure that you are using the real textbox control and not some custom user control.
It is also possible that the changes you make in designer and code are not written into the exe.When you debug your project, you might be seeing an old version of your program in which the properties might be set to false. In that case you have to simply delete the exe in the bin\debug folder and rebuild your project.

I've taken over a project, which contains some UltraWinGrid controls on some of the forms.
On one of the original forms which has been there since before I took on the project, there is a ContextMenuStrip, which has just one ContextMenuToolstripItem on it, captioned 'Default for Column'.
This ContextMenuStrip is hidden by default, however, when the user right-clicks on the UltraGrid, the ContextMenuStripItem is displayed on the grid (rather than at the top of them form where the ContextMenuStrip is).
I'm trying to replicate this behaviour in a new form that I've added myself, however, after adding the ContextMenuToolstripItem in, I cannot get it to display when right-clicking my grid.
I've put a breakpoint on every subroutine in the in the older forms class, and none of them are triggered when right-clicking it.
Additionally I have also searched the class for DefaultForColumnToolstripMenuItem, and the only place it appears is in the Click event of the ContextMenuToolStripItem itself.
So, how else is it possible to show it when right-clicking the grid? I've copy and pasted the ContextMenuStrip from the old form onto the new form and still nothing occurred.
I'm assuming it's in a property somewhere that I'm missing?
Check for a ContextMenuStrip property on the UltraWinGrid. You can set it in the designer and your context menu will appear on right click without having to deal with the MouseClick handler, checking the mousebutton used, etc.
I have a set of controls which are added dynamically to a panel. The number of controls depends on which tab a user selects from TabPage control, which is embedded in a form.
At the moment, the controls don't appear in Designer, but appear during execution.
I managed to display controls for other forms which are not dynamic by moving the non-design code to the vb file, but how can I display the other ones?
The only answer that I know of is to add your code in the .Designer.vb file of the Form.
BUT! I strongly advise you to avoid that if you are not sure how it works! Custom code in the .Designer. files can break your form design and project with possible random crashes.
Also, your code can be changed and removed by the Visual Studio designer:
Custom code in designer.vb file goes away when making edits in design mode
Instead, you can make the panels into custom user controls and add those to the tabs.
I am working on a old project of vb6 which has hundreds if forms. I am able to run the application and have to fix a runtime error in a form which pop up. I don't know the name of the form and only have visual reference. I tried using debug but It has continues SQL statements running in a loop. Any advice is appreciated.
Thanks.
Search the code for the form caption, or the labels of controls on the form, using visual studio's "find in files" or simlar function of your favourite editor.
If the caption is set in the form design, this will take you to the .frm file the form is stored in. You can open this in Notepad or another editor to get the name of the class (which is usually the same as the filename).
If the caption is set in code, you can place a breakpoint on that line. Again, this will lead you to the code which instantiates the form.
instead of dragging and dropping a common control in vb.net, is there a way to hard code it?
or is there a way for me to be able to view the codes where a dragged and dropped object has
been created? thank you so much!
The auto-generated code is intentionally hidden in the VB.NET IDE. But you can easily reveal it. Click the "Show All Files" toolbar button in the Solution Explorer window. You'll now see the Form nodes in your project displayed with a triangle. Click on it to reveal the Designer.vb file. And double-click that to see the code.
Observe the changes in the InitializeComponent() method as you use the designer to add/remove/edit controls. It isn't perfect code, the machine generated it, but it gives you a major leg-up on what kind of code you need to write to "hard-code".
I have been working with "visual basic.net" on a "windows forms" application. While manipulating controls and adding event handlers I noticed the resultant code was being generated within a file named 'main.designer.vb'. However, if I look in the solution explorer for my project there is no 'main.designer.vb' file, just 'main.vb'.
This is not a colossal problem as it runs properly. However, having closed the 'form designer' window I now cannot reopen it! 'main.vb' has no option to 'view in form designer'.
Any advice on this?
Would it be possible to copy the contents of 'main.designer.vb' in to 'main.vb' and delete 'main.designer.vb' entirely? If I did this, the next time I manipulated the form would the code be added to 'main.vb' or would a new 'main.designer.vb' be created?
I seem to have sorted out the problem.
'main.vb' was completely empty. All the code I had generated and written directly was inside 'main.designer.vb'. However, once I made a class definition within 'main.vb':
Public Class main
End Class
and then cut/pasted all my custom event handler code and subroutines from 'main.designer.vb' to THAT class - all was well. 'main.vb' now shows the correct form icon and FINALLY offers the correct 'view designer' context menu option.
I am not sure why it happened in the first place though.
Look in the Solution Explorer in Visual Studio. In the toolbar in this window is a button called "Show all files". Click it.
Then every file in the projects folder is actually shown in the solution explorer. Expand the treenodes for the form and you will see the designer.vb.
There are also buttons for switching between code-view and designer view. Just remember to select the form in the solution explorer for the buttons to show the correct form in the designer.
