We are using a ribbon control from a 3rd party that has a bug. When you click on another app, fragments of our software still shows on the screen. The company that makes the ribbon is working on a patch, but I would like to get the app working while we are waiting. how to force windows to repaint the client area behind the form when the form is deactivated?
I've searched and been reading through posts, but most everyone wants to repaint portions of their app. I want windows to redraw what should be there when my app isn't in front anymore.
I am working with Vb.net and have a form with a combo Box. On load the form is loaded with one of the following details depending on what is stored in the database; Cancelled, Processed and Failed.
Code:
TxtColStage.Items.Add("Cancelled")
TxtColStage.Items.Add("Processed")
TxtColStage.Items.Add("Failed")
Then I have an update button and when the user drops down the list he/she can select between Cancelled/Processed/Failed. I want to be able to grey out or disable Processed and Failed, so that when the user updates the field he/she can ONLY update with the Cancelled option ONLY.
I am making an app that hides the topmost window, but when i do this, it leaves no current window selected. how can i make the highest unselected window selected?

in An MDI form , i make a childform with textboxes. these textboxes are produced by the code, like this:
For i As Integer = 0 To number Step 1
Dim TextBox As New TextBox
ChildForm.Controls.Add(TextBox)
[Code]....
In another sub within the MDI class i want to read the data from the textboxes, but got an error that says txtBox1 is not a member of 'WindowsApplication1.Form1'.This is true because they do not exist yet. How can i handle this? I think it has something to do with "delegate and invoke", but this seems to be hard to understand.

View 1 RepliesI made a birthdaylist. You can store birthdays in it, and it will alert you on the day a person has his birthday. To do that the program has to startup when the computer starts up, and give the alert if neccesary and then close itself again. This all works, but the mainform is visible in that period.
View 5 RepliesI'm trying to go to a different form my main form and while I'm using the selected form I want the MainForm to hide. I've put the code MainForm.Hide() at the top of the code of the JobInformationForm where I'm directing the program. I thought this would cause the MainForm window to hide. However, I'm getting an error saying Declaration is Expected. How do I use this MainForm.Hide() feature?
View 3 RepliesI'm trying to accomplish something and not sure it can be done or rather if I'm approaching it correctly. Is there a way to access a MDI Parent's menustrip without merging the childform into it? I've done the merge before and that works fine. Reason I'm trying to figure this out is that I've started toying with a windows ribbon control and am wondering how the menu functions are performed with this control. In other words you wouldn't create one on each child form and have some how merge them so there must be a way to do this from the parent control.
Things I've tried thus far are to create a public sub in the childform that will save the data to a database. Once the save button is clicked in the mdi parent's menustrip and determines the activechild it will then call that sub procedure on the childform. However it doesn't persist the data, in other words passes a whole lot of nothing to the database even though the values don't dissappear on the child form.
Even i have use the "BringToFront" keyword for the childform but its not working. The buttons on the main form are still displayed above the childform. But when i open another form from the childform, it is displayed properly

Hello, everyone! I'm having problems with the Activated Event in Visual Basic. When trying to click my btnNext, IF THE DATA ON THE PAGE IS NOT SAVED YET, then a message box is to appear and alert the user that the data is not saved yet. When clicking the OK button on the MessageBox, it is supposed to return control back over to the main form. HOWEVER, I can't get past the Activated Event on the main form. It crashes the program. I've tried global flags, but it still does not want to work! Can anyone please help? Any thought in the right direction will be greatly appreciated! Thanks in advance, y'all!
View 2 RepliesI am trying to migrate a vb6.0 application to vb.net. I have a major issue while executing the code under form.activated and form.deactivate. There is a difference in behaviour between form.activate in vb6.0 and form.activated in vb.net. How can I simulate the behaviour of vb version in vb.net.
I have read that the form.activated fires even when the control goes to a different application and comes back.
I recently upgraded an application from VB 6.0 to VB.NET. This application contains a timer in its form (only one form is there). But after upgrading, the timer is not getting activated. Form is using DefInstance as follows: frmMain.DefInstance.Show()

I need to create a program that when it is opened, Focus will be always in that program until someone with any way will close it. I've tried to add Me.GetFocus() in the LostFocus event but nothing happens, I've tried to add Me.activate() when the Deactivate() event raises and when I debugged the program worked but when I run the biulded .exe file nothing happens again! how I can manage this Function?

Is it possible to position a messagebox in the center of your MainForm instead of the center of the computer screen? This is really confusing for beginner computer users, if your mainform will be in the top left corner and the message box in the middle of the screen, it won't be very clear that the messagebox belongs to your application. (well to us it is, but not to old people).
View 3 RepliesI have done programs in the past with VB6 using the winsock control to receive data to be processed. I would like to do the same thing in vb.net but I am having problems. I have done numerous searches and consulted numerous books and articles, but haven't found the best approach for accomplishing the following.
I would like from 1 to 20 clients to be able to send a string to the server to be processed. It would be nice to if the clients could connect to same port and use async processes to open/accept more connections. One of the books (Visual Basic 2008 Recipes) has a recipe for creating "Multithreaded TCP Server that supports Asynchronous Communications".
I am trying to base my program off of that example and modify it for my application. The problem I am having is how to share data with the Main form and the classes that handle the communications. The TCP class has two classes contained in it. One class for listening for connection, beginning the accept client and the other class (clienthandler) for completing the connection and getting the data. I would to be able to get the data from the clienthandler class and post on the main form. I have trying to have a public property for the data but I think my confusion comes in because the clienthandler would be created new for every new client. The mainform would not know how many of the new clienthandlers were created etc.how get the data to the main form and clear the data when done. I have even considered putting data into MSMQ and having main form pull data out.
Currently, I have a LoginForm that authenticates a user and it works fine. I have a MainForm, which is displayed if a valid username and password is entered. I have done this by using the following code in my LoginForm:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]...
Now this does exactly what I want except I fear it's a work around and it's not the best approach. Also, note that I am using Me.Hide() to hide the LoginForm, is there a way to show the MainForm and then close the LoginForm instead of hiding it? Doesn't Me.Hide() call creates an overhead?
