Hello everyone,
I recently noticed a strange thing in one of my programs.
After loading the program, the task manager shows memory usage of about 2mb-5mb.
When I minimize my app to tray, the memory usage goes down to 400kb-600kb.
First of... Why is that?
And second...
If I use a certain function in my app, usage jumps back up.
I show the form again, then minimize it to tray again... Usage goes down again...
My theory is that the memory holding GUI data is released.
Any ideas?
Thanks in advance,
Shy.

That's not strange at all. 
When you minimise the program, the memory management in the .NET framework will try to release as much unused memory as possible back to windows. This may include doing a garbage collection to release unused objects. Also the system may swap out rarely used memory areas to the swap file on disk.
If you also bring up the column "Virtual Memory Size" in the task manager, you will see the total memory amount used, including the swapped out memory.
If you use a part of the program or data that has been swapped out to disk, it will be brought back into physical memory, bringing up the memory usage, but not the virtual memory usage.

Actually, it does that for about every application; it's a feature of Windows XP & 2000 IIRC.

At least the OP's program is giving memory back rather than keeping it and sucking the life out of system resources.

I have a custom Windows Forms Control. I'll call it "JealousControl".
I want to make it so that if the user puts focus on JealousControl and tries to change focus to another control on the Form that hosts JealousControl, it won't let the user do that except in very specific situations. Furthermore, I want the code that does this to be internal to JealousControl and not inside the Form that hosts JealousControl.
Does anyone know if this is possible (and if so, how)?

I just experimented with:
private void listBox1_Leave ( object sender , EventArgs e )
{
if ( System.DateTime.Now.Minute <50 )
{
((System.Windows.Forms.Control) sender).Focus() ;
}
}
See if that does what you want.

I've recently re-realized that the File Types editor for deployment projects is a POS. Associating an EXE with a file type instead of with individual commands makes no damn sense. So, to have two commands on one file type, each using a different EXE, I have to create registry entries for the second manually.
Problem is, I need to insure that the value dumped into that registry key is sensative to where they choose to install. I could swear that some time ago I saw a list of deployment project variables that could be used, like the [Manufacturer] variable. But I can't find it, and I don't know that they work in registry values.
Does anybody know what all the variables are? And if they can be used in a registry value?

|
Just in case anybody cares... Don't know what all is available, but [TARGETDIR] works. But it is case sensative.

hi
how to use callback to Update progressbar for long operation ?
|
|
|
|
|
Is the operation running in a background thread on the server? Then you can just make the operation store it's status in a database or something, so that you can send a request that will get the status and return it.
If the operation is the current request, then you can't use callback, as the server will only execute one request at the time for each user.

You've asked this question twice before, and gotten the correct answer from Colin here[^], using Reflection. Asking the question again and again will not change the answer and noone is going to write the code for you.

Hi
Maybe xsd utility can help you do what you want to do.
There is a utility included in VS2003 (I think it should be in VS2005 too) name XSD.exe that can generate a xsd schema from a dll or a xml file and also it can generate classes according to a provided xsd schema.
Regards

I'm working on a hexeditor that uses 32bit and 64bit offsets (for files over 4GB), problem is the scrollbar only accepts int values, where I want each value to be a row of hex, so the maximum would be long.MaxValue / 0x10. What's the best option to deal with this? I'm thinking the only options are creating my own scrollbar, or shrinking the value, however if the value is shrunk I want to do it cleverly, so smaller files won't have massive steps in the scrollbar.

Thanks for your help at first!
Now I'm confusing about the directions which I should choose!
I'm a senior student and have some experieces about C++ language.
Recently Micorsoft produces the Visual Studio 2005,and the C++/CLI is extremely diffrent from the standard C++.And I also learned that the MFC is numbered her days! When I want to learn the Visaul Studio 2005 development,Which direction will be my best choice.C# OR Visual C++.NET?
And could you recommend some wonderful books that will lead me comfortable to the world of Visual Studio 2005(I have no experieces in windows programming!).

go fo c++/cli if you know the basic concepts than using c# java vb.net etc will be a matter of few days (they all share oops and have diffrent syntax ) so go for concepts not syntax
It is Good to be Important but!
it is more Important to be Good

Then you don't know MFC, and have nothing to lose there, I guess.
I'd go with C#, because that's far more widely used, so you'll f ind a lot more resources out there.

C# appears the way to go at the moment. I've been a C++ developer for 10 and I've been trying to get into C# development for the last 3. In about 3 weeks I'll be starting a new job that's pure C#, no C++! Can't wait. The best advice I can give you is keep an eye on the job market, see what's in demand. Even though I'm going C# I'll be keeping my C++ development skills active, I don't want to lose them - you never know when they'll come in handy and get me a nice contact or something!
Never argue with an imbecile; they bring you down to their level, and beat you with experience.
