I am essentially running an application that creates a thread to run a Form, say Form1 by calling...
Application.Run(new Form1());
Then, the application runs another process. This creates a Form, say Form2 in the same way that Form1 was created, by calling Application.Run(). The problem is that Form1 is on top of Form2, even though right before the Application.Run() call of Form2, I call BringToFront(), which is supposed to place it at the front of the z-order. Why is Form1 on top of Form2 even though Form2 was created afterwards, and explicitly brought to the front? I would like to do this without having to call SendToBack() on Form1, since I don't want to send it all the way back, I just want it to be behind Form2.

Can you post what you are exactly trying to do? Do you want to just create 2 forms?

Create one form with one process. Then, when the second form is created, have it be on top of the form created by the first process. I don't know why that's not happening.
Process1 -> Creates new thread -> Runs first form on new thread
-> Executes another process "Process2" (completely independent of Process1) -> Runs second form

Why are you using Application.Run(Form2). This will create 2 discreet applications and they have nothing to do with each other - I think.
Z order is for controls on a form and will have no effect between forms.

Well, that's the point -- they shouldn't have anything to do with each other, however, the second application's form should still be on top of the first application's form, right? I thought that this would happen by default, since when you open up a new application, it should be the new application we're looking at, and as such, shouldn't be hidden by something that already existed.
For example, if I open up notepad. Then I open up Firefox, I won't be able to see notepad anymore. I want to do the same thing here. The only difference is that the first application's form is covering up the second application's form when the second application's form is loaded.

I guess there is a good design reason for what you are attempting but it seems really weird to me. I'm sure you are going to run into domain issues (obviously you are already).
Your example of opening 2 DIFFERENT applications is not valid. You are attempting to launch 2 forms as applications from the same stub. Even if you are opening 2 copies of notepad they are copies not the same exe. A closer example would be word where each document is treated as an application. How it's done I do not know.

Yes, I understand that they are copies, even if you run the same executable twice.
What I don't understand, however, is what you mean by "2 forms as applications from the same stub". My first form is being launched from the process I double-clicked. That one's pretty simple to understand. My second form is being launched when I create another process, so from what I understand, it is completely separate, since I'm only using the first process to call the second process. Let me see if I can give an example of this... it would sort of be like cmd.exe. When you run it, a form pops up that's designed to be like a command prompt. Then, you enter some text into this command prompt, say "notepad.exe", and it opens up notepad as a new process, and the form of notepad is on top of the form for the command prompt.
If my example is not a good one, could you please elaborate further? What I just gave above seems to make logical sense to me...

Same issues applies, you are running cmd.exe to get the dos prompt and from there you want to run notepad.exe. You are hitting 2 different exe files.
Your application compiles into 1 exe and from that your want to run 2 applications. Do you want 2 apps or do you want 1 app with 2 threads.

I think that that Form.Activate method might do what you require. This brings a form to the front of Windows so that it would appear on top of anything that you have open.
I have been using this from a notiify icon so that that double clicking the icon will bring the form to the z-order of all open windows apps. I assume this will work for threads within the same application but I haven't tried that (I'm not too familiar with threading code)
Bye.

Hi,
This worked for me. What I was doing before was:
Form2 form2 = new Form2();
form2.BringToFront();
Application.Run(form2);
Then, I tried:
Form2 form2 = new Form2();
form2.Activate();
Application.Run(form2);
This didn't work either, so I tried:
Form2 form2 = new Form2();
Application.Run(form2);

Application: I have a Windows forms application which interacts with COM components to update data in the Oracle DB.
Whenever I try to update the data based on a condition it never works in the full run using the release exe. But when I try the same thing through step by step debugging of the release exe, it works fine and updates the DB.
This appears quite strange and inconsistent. Can someone throw light on this?
Regards,
SPanicker.

Does the information in your applications logging data suggest anything?

You may be running in to a case where the runtime is being too agressive and running a GC too soon. How are you acessing the COM components? If you're doing this in a managed wrapper, it should implement IDisposable and include calls to GC.KeepAlive() in the appropriate functions.

Mike/Dorman thnx for the great inputs. I have looked into all of these issues but I find no clue why this is happening.
Is this some kind of weird inconsistency which is particular to .NET 2.0+Win2000 I am using???

Hello, is it a good way (and easy) to use skins (visual styles) in c# with .net ?
I have a custom control called XPExplorer Bar : http://www.codeproject.com/KB/miscctrl/XPTaskBar.aspx
It's a great control and to use a skin with it (from a .dll that contains an UI file) I just use something like :
taskPane1.UseCustomTheme("themes/4.dll");
If I use the above line the visual style from the DLL is applied to the control.
I would like to do the same with the TopMenu (the menu strip) and other buttons/controls ...
I hope some one can guide me with this, thanx

It is not as simple as that for using visual styles in applications as everything is drawn using the uxtheme WinAPI within Windows XP/Vista.
One of my articles might be able to assist with a different method of theming controls with WinForms. Theming in general gets easier with WPF, but even then you are not able to alter aspects using visual styles of the uxtheme engine.

I'm in need of a deployable database solution for my Windows Forms projects. VS.NET has Local Database (.sdf) which asks you to install SQL Server Pocket Edition and Service-based Database (.mdf) which requires SQL Server Express to be installed. What can I use for my project that I can deploy in a setup?
|
|

You can just deploy an access DB, I thought. But, that is an mdf file. I guess they are moving away from that, because it sucks. I thought there was also a SQL Server embedded, which becomes part of your exe, but I am vague on the details, I keep meaning to look into that for my app.

I am not going to do the work for you, nor can I open your head and pour in the knowledge you need to implement a .NET remoting solution. Perhaps you will have to go learn .NET remoting so you can use it, what do you think about that?
