Dec 7, 2009
I have a text box called TxtSearch on my form. The value entered should always be numeric before the search can be done if its any other data type the following Message box is give - Only a numeric value is allowed in this field", MsgBoxStyle.Information, "GCPM.. (Code shown below)

The TxtSearch doesn't prompt the message and when you click the Search Button the application crashes - dsiplaying an error converting data type varchar to numeric.. What I want to do is if someone uses the copy and paste tool to enter the value in the textbox- TXTSearch and there is a datatype not numeric the message prompt is called ..

I have a Windows Forms app, with a TabControl. On the first tab (which is a bunch of textboxes), the CTRL-x/c/v keyboard shortcuts for cut/copy/paste work as expected. On the second tab (which is a DataGridView), the keyboard shortcuts don't do anything. How do I hook up these keypress events to my cut/copy/paste routines? I already have great cut/copy/paste routines for my DataGridView--and they work fine when launched from the tooltip buttons or menus. I just need to hook up those subs to the CTRL-x/c/v keypress events.

I have a small copy/paste type of program. You put text in the boxes, click copy and it copies it to the clipboard. I have a text file attached to format the text when it is copied. what I want to accomplish is...If I don't fill in every single textbox with text, I don't want that particular field to show when I paste it. Example, I have the layout like below on the text document.
textbox1.
textbox2.
textbox3.
No matter what, when I click copy, the text document is going to copy textbox1,2,and 3. If I only put text in textbox 1 and 3, I don't want it to copy textbox2 if its empty.

to know if a control have any handler. I have a dgv and in the editing control Showing event i add an event handler like this: VB AddHandler e.Control.KeyPress, AddressOf Grid_KeyPress_NumbersOnly This event it's added in some of the columns and for the other ones i remove it... The problem it's when the user, for example selects 3 columns where the event it's added, then if the user selects one where the event it's removed, it doesn't remove all handlers... So i have 2 solutions, when removing i put multiple removes or the other check if the event handler it's added doesn't add again. I prefer this second option, but i don't know how to check if the event it's added?

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

in VB6 the Copy/Cut/Paste etc. feature could be setup with "AutoVerbMenu". In .net 2008 this feauture is not available as far as I know, thus I configured the functions manually.
Everything work so far as expected for my first RichtTextBox.

In my Sheet1, i will be having a data From column A to F and in Colunm D (The Red one) it will be empty, The data can be 10 rows or might be more the 60 rows sometimes and in Column I i will have some more Data.
Now i need a macro where in sheet 2, Automatically the Lines from Column A to F should get pasted and it shlould take the Column D from column I. Once the Total line are pasted the it should go for next list of Column I.
Exm: IF i have 50 lines in Column F and in Column I i have 5 lines Then i should get the result of (50x5=250 lines) 250 lines each of 50 as per Column I.

I have a datagridview and I would like to be able to select an entire row by clicking on the row header column, hit CTRL+C, then put the cursor in the next row, and hit CTRL+V to paste the contents.
Right now, it pastes all of the contents into the first cell of the new row. If I paste the contents to the clipboard, I see them correctly and they are tab delimited.
Once I get this working. I would like to be able to copy and past multiple rows at a time.
FYI, I am not using a data source at all. Most of the rows are combo boxes where a user is selecting values. There is no database connection.

I have an problem with copy and paste between 2 richtextboxes part of the problem is if I new the 2nd Richtextbox actual name I could paste it using rtf format because I have so many of them I use a loop to go through the controls until I find the right one using typeOf control. The problem is with that that it really doesn't act as a richtextbox. See code below.
Dim RTB As New RichTextBox
RTB.Name = sender.Tag
For Each itm As Control In EnumerateAllControls(Me)

I am working on a project that requires me make a MDI, which I did. The problem that I am having is that none of the menus like the cut and paste work in the MDI Child. I have tried different types of code and still can't get it to work. All I am trying to do is copy or paste text using MDI parent menu controls, rather then creating menu controls for all the MDI children

I have 300+ excel files that need to be combined. There are 4 different types and in 4 different directories on my network. I need to copy the data out of each one and combine the data into a new single workbook (1 for each type). I have come up with a solution that does MOST of what it is supposed to do. Only problem is I can't figure out how to have the paste operation go to the same single workbook. No matter what I have tried it opens a new copy of excel to paste into everytime. Here is what I have so far.[code]...
