Hi,
I've seen similar problems. The first thing I would recomend is to write Open and Close methods. Make sure you check the return values for any errors and display a message box with any error so you can se exactly what the problem is. Then add calls to these from, say, a menu. E.g. a Comms menu with Open and Close options. This will allow you to test if the port truly gets closed when you call Close. Can you then perform Open, Close, Open, Close with no problems?
This separates closing the port from the closing of the application.
Once the Close is proven, then add it to the OnClose window event rather than the destructor.
I'm afraid I don't understand what you mean about closing the application but the exe still running. Do you have a client and server and you close the client in task manager but the server (exe) is still running?

Hi,
Thanks for your reply.
am using the write , read and close functions.after closing my application, if i try to open once again, it says that still exe is running. so i used to task manager to close th exe.
thats the problem happening here.

Well, I'm not sure how much significant is my reply. Usage of TerminateThread()[^] can end up in application handups. If you're calling them just remove it.

As I've noticed, Windows Explorer uses the icon with the lowest ID within an EXE file to represent it to the user. Is there any way to change this Icon for EXE files dynamically? (I mean replacing it with a custom one)
Thank you masters!

This pretty girl[^] knows how to replace resources in EXE and DLL files. She probably also knows how to use the codeproject search engine. How does that make you feel?

As a practical suggestion, if you have some type of malware installed on your system, it can be very difficult (even for an expert) to determine what it is and where it lives (and, of course, how to terminate it).
I would start out by downloading: Process Explorer, by Mark Russinovich[^]. It's a FREE utility, written by one of the authors of "Windows Internals". It provides a wealth of information.
To answer your question, "How can I run my code in this manner?", you should check the Forum at EvilDoers.com (OK, just kidding),...but, there is no simple answer. It depends on many factors. I could be as simple as writing an ActiveX component or a Shell Extension (tutorials here at CodeProject), or, it could be as complex as a Windows rootkit. I suspect that nobody here will help you with the rootkit. But, you can GOOGLE, say rootkit[^], and you will find an enormous amount of information on the subject.

Hi everyone
I'm having some trouble solving this problem, if you guys could help I'd appreciate.
A guy has N stores. He just received a shipment of K boxes and wants to distribute the boxes in order to maximize profit. The input is a NxK matrix, where matrix[N][K] tells you the profit he would get, sending K boxes to store N. One wants to know the maximum profit he can get (not necessarily the way he gets it), and how may ways can he get it (number of combinations that totalize the maximum profit).
Any suggestions?
Thx

Hmmm, seems like homework, you'll probably get more help if you post what you have tried and ask specific questions about what you don't understand.

Hi.
I have 3D CAD data. And I would like to create an icon and associate it to my 3D CAD data, so that I can see file view with it's 3D view thumbnail.
Is there any way I can attach/associate icon to existing file?
Thank you for your attention.

|

I think you have to implement IExtractImage[^] interface to display the thumbnail of your own file. Well, check this article[^] about how to do it.
Regards,
Jijo.

Hi,
I have a dll which i am registering using regsvr32.exe. I would like to know how can we find out programatically that this dll is registered.
Thanks
SNI
|
|
|
|
|
The DllRegisterServer[^] entry-point in the DLL defines what regsvr32 should be setting in the registry. You could write a set of registry query function calls to verify that information has been written correctly?
Alternatively, maybe you could try using the COM object registered by the DLL - if regsvr32 hasn't run correctly, then the COM object won't work.
What's your motivation for doping this, anyway?
|
|
|
|
|
Thanks for reply. I would like to check whether perticular DLL gets registered or not before starting my application.
SNI
|
|
|
|
|
In that case, creating a COM object implemented in the DLL should do the job - that's why you want the DLL (for the COM objects it contains, as it's a DLL registered by regsvr32). If the object creation fails, you know there's something wrong with the DLL or its registration.

These activities seem to be a kind of spying! 
Any way after a few days working on it, I understood the offspring of all these things is "Windows Explorer"! 
apparently there is a spyware running on my system which has no process and do what it wants behind "Windows Explorer". there should be a DLL some where on the computer in which all these codes lie.
