Step One: Upgrade your version of Visual Basic. Visual Basic 2005 Express edition is free and accessible, vb 4 is seriously outdated, insufficient and unsupported for anything. VB.net 2005 is much more effective for any application, it is now much more than a glue and paddlepop sticks microsoft response to a more "understandable" interface and has become nearly, if not as, powerful as C.

Step Two: Try the maths forum, right here on Code Project.
Any thing mathematical, those guys can help. Oh and try to make your question abit more concise.

What "mouseover part"?? Part of what??

Yeah, it's called a "menu item". You open your text file, then create items in your File menu from that. There is nothing to do with a "mouseover" event. What's the problem??

I'm 51 and a total begginer. So things like this take time to stick.
So there is a small problem
But thanks

when the mouse hovers on the recent files menuitem, as you know you get a submenu with the list of recent files. how do i get the list to read into the recent files submenu from the text file.
sorry to be a pain in the rump.

Create a menu item under your File menu with a name of, say, RecentFilesMenu and some appropriate Text.
Here's an example of adding submenu items to a menu:
RecentFilesMenu.DropDownItems.Clear()
For x As Integer = 1 to 5
Dim filename As String = String.Format("Filename{0}.txt", x)
Dim newItem As New ToolStripMenuItem(String.Format("&{0} {1}", x, filename), Nothing, AddressOf RecentFile_Click)
newItem.Tag = filename
RecentFilesMenu.DropDownItems.Add(newItem)
Next
You'll, of course, need a method to handle the clicking of those menu items, so....
Private Sub RecentFile_Click(ByVal sender As Object, ByVal e As System.EventArgs)
If TypeOf sender Is ToolStripMenuItem Then
Dim menuItem As ToolStripMenuItem = DirectCast(sender, ToolStripMenuItem)
Dim filename As String = DirectCast(menuItem.Tag, String)
' Call your Load Document code here...
End If
End Sub
|
|
|
|
|
When the program begins you should create menu items and append them to the appropriate menu from the data in the data file.

Can I include code that's in a textfile at runtime in vb.net? I'd like to allow the user to modify the code before the run. Seems like an easy way to do that is to allow them to edit a textfile which becomes part of the code while executing.
Thanks

I would assume that the basic .NET runtime does not include a compiler.

No, you can't include code into an assembly that has been compiled already. You can compile the code into a separate assembly and then load that assembly and use classes from it.
Have a look at the Microsoft.VisualBasic.VBCodeProvider class.

I am building a control, within this control is a data grid...The data grid needs to be changed depending on the form that it is on...but when you build a control and then drag it onto a form...you can no longer edit the controls that you placed on that control...any sugestions?

The control shouldn't care about what form it's on. It should be modified by the form code only if necessary.
Polymorpher wrote: you can no longer edit the controls that you placed on that control
What does this mean? How do you want to "edit the controls"??
|
|
|
|

My control contains a grid control as well as some other controls, when I drag my control onto a form from the toolbox, I want to be able to move the grid within my control and change some of the settings on the grid etc.

You're going to have to add code to your control to handle dragging the grid around at design time. The designer won't do it for you because it doesn't support designing constituent controls seperate from the user control that contains them, at the controls runtime.
The properties will all have to be re-exposed as public properties of the user control.
A user control's runtime doesn't begin when the forms project the control is used in is finally run. A User Control's runtime begins when an instance of the control is created on the host form.
From your description, it sounds like it would be better to just break the datagridview out on its own and not have it as a constituent of a user control.

Hey all!
Got something i need help on.
How can i make a panel's vertical scroll bar to act and control another particular datagrid or another component for that matter.
So when the vertical scroll is moved, both the panel and the other form(eg; datagrid) should be scrolled as well.
Thx in advance!
regards,
Jensen

You can checkout the response to an article here[^] that describes an alternate method to the articles method.
Either will work...

Hello again!
Im' having a tough time to solve this... really need help!
As Dave had pointed out to me this article here[^], i've tried the method suggest by the response to that article and what i've found is that it works when im implementing it to synchronize two richtextboxes....but what it dint' work its when ive tried the same concept to synchronize them with either two data grid / panel / or the combination between both.
Could someone check this out?
Thx in advance!

jensen

I am just starting out with VB 2005 express, and I'm having trouble defining global variables.
I want to use (read and write) the same variables in many different class subroutines, so I want to declare them as global variables.
To do this I created a module called modMain, and defined the variables in the declarations section of the module using script such as
Public strPartNumber As String
Public Const c_ItemNumber As Integer = 1
Public strPartArray (300,5) As String
When I run the code, the program stops at the line within a class subroutine, in which I am trying to change the value of a variable with the command:
strPartNumber = "QQQQ"
The error returned is 'TypeInitializationException was unhandled'
I'd be grateful if anybody could tell me what I'm doing wrong.
Thanks
Andy Scott
