View 4 RepliesI'm an old Access developer and know VBA quite well, but now I'm working at learning VB.net. I'm trying to find the equivilent of the following Access VBA code using VB.net:
Function EvalField()
Dim x As Integer, ctl As Control
Set ctl = Screen.ActiveControl
x = Val(Mid(ctl.Name, 5))
Screen.ActiveForm.Controls("Formula" & x) = ctl
ctl = Eval(ctl)
UpdateTotal
End Function
This code sets a control variable to the currently active control, then copies the text from that control into it's matching "Formula" field for reference by the user), then turns the string of math into the answer. For example, if the user enters 5 + 4, that will be copied to the Formula textbox, then it will be evaluated and the answer will replace the 5 + 4. And lastly, the UpdateTotal sub will execute which will add this answer to the existing Total field.
I have a tab control with two tabs. Both tabs have controls which are unique to them, but there is one control which I would like to always appear on whichever tab is currently active. I figure I just need to add some code to TabControl1_SelectedIndexChanged(). I tried

TabControl1.TabPages.IndexOf(TabControl1.SelectedTab))
MyControl.Parent.Update() ' is this necessary?

I have developed an active x control and signed it with certificate. I know that digital signing is needed , so that the browser knows that the active x comes valid source.My asp.net form has a button , which invokes a method on activex control as -[code]....
But it errors on browser stating that the - IE has blocked this site from using an active x control in an unsafe manner. ( Please see attachment).So should I have to develop the active x control which implement IObjectSafety and also signed digitally, so that it can execute on client browser without any warnings from IE. Any examples.
I'm using VB.NET within Visual Studio 2008.I have a ActiveX control on my form that contains a method that takes an Array. In VB6 I just passed in the array and it was populated OK. When I do the same in VB.NET, I get a result but the value of each index appears to be a pointer.Here is the C++ method code...
void CMyCtrl::GetRowInfo(const VARIANT FAR& vArray, short sNumRows)
{
// Declaretemp array to put the row list into
short asRowList[24];
[code]....
Here is the VB code (same VB6 and VB.NET...
Dim maintRowList(0 To 23) As Integer
AxMyCtrl.GetRowInfo(maintRowList, 24)
In VB6, the value of maintRowList(0) is in the range 0 to Windows screen height(its a pixel value)In VB.NET the value of maintRowList(0) is a value that looks like a pointer to me (e.g 285671429).In VB.NET, the type of the 1st parameter is Object. In VB6 it is a Variant. I've tried AxMyCtrl.GetRowInfo(maintRowList(0), 24) and got the same result. I think I need to get a pointer to either the array or the first element of the array but I can't see a way to do that. how I can pass an array to this type of C++ ActiveX method?BTW - I cannot change the ActiveX code so the solution must be within VB.NET.

Is there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.

something similar to:
