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

MDI Application - How To Get Active Form

Mar 11, 2010

I have a mdi application. When some childforms are open (but only one is active) and the user press a button, I want to know, what form is open, because depending on this, an event will fire up. I imagine this so: at first I determine the active form with a separate function. And then with a select case statement the event will be fired up. How can I make this?

Determine If A Form Is Already Open In SDI Application?

Feb 2, 2010

My program has many forms that can be launched from the main form, and when launching a form, I need for my program to know whether or not there is already an existing instance of the requested form open before it launches the requested form.

So, if I have form "Search" with button "View" that launches form "Details", I need to know if the "Details" form is already open when the user clicks the "View" button.

Apparently, if I had developed my application as an MDI application intead of an SDI application, I could just do "If frmDetails.visible = True then DoStuff()", but the Details form's Visible property always comes back as False, even when the form is already open.  If the form is always being reported as not being visible even when it is indeed visible, what method do I use instead to find out that the form is open/visible/in use?

Determine The Top Most (zOrder) Window Other Than The Form?

Dec 21, 2011

im trying to find the top most window other than my form or its parent form...Background:Im writing software for a TS-MFD (touch screen - Multi function display), it has a docked menu bar at the bottom with the option to pull up an onscreen keyboard. Now the keyboard ive written and works well but the only drawback is i need to specify what window to send the keys too, be it inside my own application or a 3rd party app such as notepad. I believe the answer lies an recursively looping through GetForegroundWindow() from user32.dll and ignoring "Keyboard" and "MenuBar", but I dont know how to advance to the next top most window, i only know how to get the top my window order is likely Keyboard,Menubar,(then the window im trying to grab)?

Determine Which Control Called A Form?

Mar 3, 2010

I have three buttons on my main form, say Form1. Clicking any of the buttons brings up Form2 modally for input, it's a number pad. Now, depending on which button was clicked to get there, after the user enters his numbers, I need to change a specific label on Form1. In other words, btn1 clicked puts user input into lbl1 and so on... I could probably do this with a variable but wondering if there is a more elegant way.

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.

Active Form In Windows Application?

Oct 7, 2009

I am developing a Windows Forms application. I have four forms which is inherited from Baseform in another project. In all four forms I am using a label to show some transaction count based on network status. I have implemented a thread which gets the active form of application and setting up the text. The code works fine if application screen is active. If I minimize and open any other application, I am getting an null error exception.

How do I get the active form of an application?
Private Sub StartThread()
pollThread =New Thread(AddressOf PollfileStatus)
pollThread.IsBackground =True
running =True

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 I'm trying to find the equivilent of the following Access VBA code using

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)
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.

How To Make Window/form Become Active Foreground

Apr 21, 2010

I'm using Visual Basic 2010 Express.I have a form that can be minimized.There's also a tray icon.I've coded it so that if you double-click on the tray icon, the form's FormWindowState becomes set to Normal; this restores the form to where was before it became minimized, but the form does not become the active window on my desktop.

How can I make the form become the active most foreground window? I've tried various functions that I can think of but no luck yet. Tried searching with various queries to try and find the right wording but no luck.I'm new to Visual Basic - only started a couple hours ago.Probably something simple but I can't seem to find the correct function or anything.I have the form/window open, and then I overlap said form with a window of another application. When I double-click my app's tray icon, I want my window to become the active window, bringing it to the front, but can't figure out how

VS 2008 Determine Mouse Idle Time On Form?

Mar 31, 2009

way to reset a timer if there is form activity so it will not expire until the mouse has been at rest for 2 minutes.

This timer runs for 120000 milliseconds usually, and sometimes it lapses (and logs you out) when you are in the middle of editing. Sometimes 2 minutes is not enough time to do all the edits. So I wish to reset the remaining interval as long as there is mouse activity. But I am not sure the best method to do this?

I have found the mousemove event but to me this seems like it's going to fire way too often and tax the resources if I preform operations here, maybe not? Is there a better way to get this functionality?

I want this functionality so that if someone starts editing on the UI and walks off/gets distracted it will lock the grids back so that some other user can't come dork things up.
