Ctrl P ? What does that even do ? Do you want to disable it in your app, or across the system ?

It's usually the shortcut key combo to bring up the Print Dialog. Usually... With all the wacky people writing code now-a-days, who knows what it'll represet from one application to the next any more.

Christian's question needs to be answered in order to answer your question. Do you need this capability system-wide or just in your application?

It's funny how many people ask vague/unanswerable questions nowadays and never respond when you ask for more info....

What are the various aspects that can be considered to check whether my program is installed on the machine.
I mean if i am naming my setup as setup1 .... then it is possible to create an another setup which will have same name
in the control panel u will find
setup1
setup1
two times.

First of all, name your setup program after your application. Then, you shouldn't have any issues.
If I want to check if my app exists, I create a registry key within the app, that I can then check for on the machine.

Thank You

It is all based off the productcode and upgradecode. You can name your install programs both setup as long as you don't store them in the same directory and have separate setup projects for each.
Take a look at an article I wrote, it might be helpful.

For Each dg As DataGrid In DataGrid1.DataBindings
Dim cb As CheckBox = CType(dg.Item.Controls(1), CheckBox)
If cb.Checked Then
Dim id As Integer = Convert.ToInt16(dg.Item.Text)
endif
the above code is vb.net windows application code.
when i run the above code,the following error is shown.
"Overload resolution failed because no accessible 'Item' accepts this number of arguments"
this error shown in dg.item (2nd and 4th line).this code is for edit.how to solve this.can u send other vb.net windows apllication code for edit a record in datagrid.

Your code all the way though assumes that it's cast operations will work. Write code that is more defensive, step through it in the debugger, and you will probably see what the problem is.

This code has so many problems on so many levels, it's hopeless to try and save it.
You said you wanted to change the status of a field in the data that this grid is showing? You don't do that in the DataGrid, you do it in the DataSet, or DataTable, or whatever else this grid is bound to.
Think of it this way. The DataGrid show you a view of your data, it doesn't hold the actual data it's showing you.

Hi All,
I am working with VS.NET 2005 datagridview. For the past 2 hours i have been screwed up by this grid behavior. I have 12 columns in my datagridview and I want 1 of them (which is checkbox) to be editable like user can check/uncheck it. When I bound the grid to datasource (dataset), it will not allow me to check/uncheck the checkbox column. I debug it and it shows the column readonly property set to false which is OK, but why it didnt allow me to edit it. Same happens in Virtual mode of the grid.
Do you have any idea how can I make columns editable in normal and virtual mode with Bound columns?
Thanks,

Did you set the DataGridView.ReadOnly property to True?
|
|
|
|
|
No the readonly property is set to false. And I have set ReadOnly property for each column

Please can someone tell me how to drag a file from my explorer window on my form and load the file into a rich text box that i have created at runtime? thank you, in advance
|

hi,
to do this, you need to set the allowdrop porperty of the control to true.
then you need to write two event-handlers to handle the events fired when you do drag & drop operation.
below is a code sample in C# but you can easily convert it to VB
//you need to set the property and assign eventhandlers
this.richtextbox1.Allow = true;
this.richtextbox1.DragDrop += new DragEventHandler(richtextbox1_DragDrop);
this.richtextbox1.DragEnter += new DragEventHandler(richtextbox1_DragEnter);
//then write the event handlers
private void richtextbox1_DragEnter(object sender, DragEventArgs e)
{
if(e.Data.GetDataPresent(DataFormats.FileDrop))
{
e.Effect = DragDropEffects.Copy;
}
else
{
e.Effect = DragDropEffects.None;
}
}
private void richtextbox1_DragDrop(object sender, DragEventArgs e)
{
if(e.Data.GetDataPresent(DataFormats.FileDrop))
{
string[] file = (string[])e.Data.GetData(DataFormats.FileDrop);
fileName = file[0];
//Now that you have the file name of the file, you can read it and display its contents
}
}
hope this helps.
regards

on formload
textbox1.dragdrop=true
Private Sub TextBox1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox1.DragDrop<br />
If (System.IO.File.Exists(CType(e.Data.GetData(DataFormats.FileDrop), Array).GetValue(0).ToString()) = True) Then<br />
If (System.IO.Path.GetExtension(CType(e.Data.GetData(DataFormats.FileDrop), Array).GetValue(0).ToString()) = ".txt") Then<br />
TextBox1.Text = System.IO.File.ReadAllText(CType(e.Data.GetData(DataFormats.FileDrop), Array).GetValue(0).ToString())<br />
Else<br />
MessageBox.Show("select the .txt extention file")<br />
End If<br />
<br />
End If<br />
End Sub<br />
<br />
Private Sub TextBox1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox1.DragEnter<br />
If (e.Data.GetDataPresent(DataFormats.FileDrop)) Then<br />
e.Effect = DragDropEffects.Copy<br />
End If<br />
End Sub
Hope this may help You.
