View 3 RepliesI think there is something wrong with the themes i use, aeonhacks' by the my program is all okey now, except the startup even i set the location on centerscreen when i run it, it doesnt show up on the center screen? anyone encounter this before?
View 2 RepliesI can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.
well i successfully docked a perpixel alpha form with the main form(form1). but the perpixel alpha form always appears at the top left corner of the screen and when i move the main form the form(perpixel alpha form) inside it dosen't move it stays at the top left corner. ALWAYS. to dock the perpixel alpha form i used
Me.toplevel = false
Me.parent = form1
I am using vb.net 2008 i have been using a mdi form which is the startup form for my prog. and i have a main menu on that form. now i would like to shift to tree view as my client has asked for it. whenever a node is selected i can select the form corresponding for that particular code. everything is fine till here. but when the form is loaded the tree view is coming on top of the form the tree view is docked in a pannel. now i have tried everything treemenu.sendtoback and the say the form to b called is taxtypemaster then taxtypemaster.bringtofront but still the tree view is coming over the form
I have tried the following :
Dim mMenuSelected As String = e.Node.Name
Select Case e.Node.Name
[CODE]...
Even the visible doesnt work as it seems after the .show it makes the tree view visible again. how do i hide the treeview pls. someone guide me at the earliest. i feel it is not the prob. of treeview but something to do with the mdi form am i right ?

View 1 RepliesI've developed program w/ VS 2005 .net 2.0.... the program works great on all my customers computers, except for one. Immediatedly whenever opening the program he recieves a clr20r3 error and the process terminates.

What I want is -

I have a project in VSTO/VB using a BackgroundWorker that works fine. It is a form that calls for a web page of information. The web page can take a while, so I have the form calling with the BackgroundWorker.I then have an Excel Addin project that has added the BackgroundWorker project. When I call up the form from the Excel Addin project and use the BackgroundWorker to request the web page, it grabs the web page ok. But the work done upon completion, during the BackgroundWorker1_RunWorkerCompleted method, is resulting in an error message:

View 3 RepliesVB2008 application.
Using a splashscreen.
When the spashscreen is done, the main menu for the program appears.
The problem is that the main menu appears UNDER things already open on the desktop.
Always On Top could be the answer BUT if I do that, all sub-menus will be UNDER the main menu rather than stacked on top.
I continue to get this error when using the code samples from Cengage's book Zak's Programming with Microsoft Visual Basic 2008. I am running Visual Studio 2010.I am attaching the code below:

View 2 RepliesI have an problem to assign a startup form in vb.net. I have three forms:
1) Registration Form
2) Login Form
3) Main Form
Firstly i have set set startup form as registration in properties =>Application after registration completed or saved i am displaying the Login form by hiding the registration form. and entering username and password it displays the Main form. Now the twist when i exit from application next time i started to run my project where i can check if their is entry in registration form it will directly goto login form.
I need to put following code in the Constructor of my startup form.
JohnKenedy.BusinessSQLEXPRInstaller _ins = new JohnKenedy.BusinessSQLEXPRInstaller(" _ <Installation Display Name>", "localhost", "<New database instance name>", _
"<new database name>", "<database password>", "<database backup filename>");
if (_ins.IsDone == false) _ins.ShowDialog();
if (_ins.IsRestart == true) {
Application.Exit();
this.Close();
return;
}
But I really do not know what the Constructor is and how to access it?
make my application choose which form to startup using an IF statement. Where can I type my IF statement to make it work that way? Please explain in very simple terms.
View 2 RepliesI created a VB.Net Windows Forms application and my Form1 is my startup form. I want to have a class be my startup file instead of my form. In c# you have program.cs which does that for you but I cant seem to find something like that in vb.net.
View 1 RepliesHow do I do it, I suppose it would be through properties but Im not sure where
View 2 Repliesthis might be a really dumb question, but if someone could enlighten me I'm writing a Winforms application in VS2008 vb.net.The application starts with a main form. I've got a status bar at the bottom of the main form, indicating the application status. I've got a 'SetAppStatus' method on the Main form.
I'm writing a class that needs to update this status. So in the class I'm Importing the Main Form. But I don't know how to call this SetAppStatus method because I don't know what the instance of the main form is called Plus am I doing this the right way? I'm still grappling a bit with how .NET all fits together and it can get a bit baffling :)

I have a VB.net program that originally had a form. I added a module and then deleted the form, but now I get the error...
"A startup form has not been specified"
With VB6 I would change the startup object to sub main, but I can't see how to do this in the properties of the project. I tried changing the application type to console, but then I get the following error...
No accessible 'Main' method with an appropriate signature was found in 'WindowsApplication1'
How can I do this without using the original form?
When developing a Windows Forms Application, I can see in the Application.Designer.vb file where Me.MainForm = Form1, but I can't find where/how Form1 actually gets newed-up.
View 3 RepliesI have a VB.NET project and I want to know how I can call a class called StartUp.vb BEFORE my logon form.
Here below is the coding of Startup.vb class
[Code]...
The problem is: I couldn't find a way to call this StartUp.vb file and therefore I am unable to call my LogonUI form, I also try to "right click" the vb project and select "properties" and go to "Startup form", couldn't see the class of "Startup.vb" showing up
I've got a single form application.
In the Sub New() of that form I'm creating two database classes.
In those classes if I get database errors (such as connection issues) I'm messagebox'ing the error message and setting an ERRFLAG property.
Back in the Sub New() I'm checking that ERRFLAG and I thought I could ME.CLOSE() - but that's not working.
What all is best practice for this type of operation?
This is what I had up to now
Sub New()
Me.CMCStarting = True
' This call is required by the Windows Form Designer.
