How To Find Name Of Active Control On Form

Mar 12, 2009

I'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.

Forms :: Skip Validation Of Active Control When Form's Close Button Is Clicked

Aug 12, 2009

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.

Write Text From A Parent Form To The Active Mdi Child Form VB 2010

Jan 28, 2012

It has to be a simple line of code but I do not know how to construct it. Using VB 2010 Express, I have a MDI parent form and many child forms. I want the parent form to determine what child form is active and load data into the RichTextBox1 on the child form. Each Child form has a RichTextBox1. The parent form gets its data by loading a file.

I am close to a solution but just can't get there. You will see in the code below, if I make a direct reference to a specific child form, it works great. What I want to do is to use the Active Form function to determine which form to write to. I have looked at the MS tutorial which gets me close.

Sub OpenToolStripMenuItem_Click(ByVal sender
As System.Object,

Pass Integer Array To C++ Active Control?

Mar 12, 2009

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.

Active Directory Groups In Form

Sep 18, 2008

I am writing an application where active directory validation is required before accessing the main form. There are 2 forms. Form 2 is the login form and form 1 is the main form. The main form would have a simple look, with about 10 checkboxes.I have managed to get the authentication working great but what now need to do is validate groups. Say if "user A" is in "groups A,B and C" and "user B" is in "groups B and C" i would like for them to use my login form, once they log in, the groups that they are members of would appear in a listbox on either form, (whichever is easiest) and is hidden from the user ... if they are in group A, then the main form would show only the first 3 checkboxes, if they are in group B, then it would show the 4th and 5th checkboxes, if in both groups then show the first 5 checkboxes etc.It is a simple idea, but is complicated to explain.As i said, the login form is working with the active directory... here is the code for the login form:[code]Form1 in the code is my main form, and wish for it to change according to which groups the user is in.
