i got a headache of that..i'm a newbee to these stuff so please give me some more details about what to link statically and what to link dynamically..
i'm using static linking between my c++ dll and APIs contained in it.and using the usual Declare statement in VB to call my dll's functions..what necessary steps i need to make to solve the problem..
note:the article suggests writnig something like:
typedef BOOL (* _stdcall fnptr) (HWND, COLORREF, BYTE, DWORD);
but this didn't work either..

The code wihtint he C++ DLL needs to load the library, like suggested earlier, then use GetProcAddress to obtaint he function from it, and only call the function if it gets the address, otherwise, you are on a version of the OS that doe snot have the function supported yet.
Something like this:
VB can statically link to C++ DLL
C++ DLL dynamically loads library and gets procedure address
If procedure address exists, then function is called, otherwise, it is not (obviously..)
Then it will work, and you can load your VB application without the error about 'function not found' coming up.

it's not working man...
i uploaded the project so you can download it and see what's wrong...
after downloading you should build the dll and build the VB example project to the debug folder...

didn't you set an option like "always visible" or something like that ?

That's the behaviour one usually wants from a modless dialog. What is it you want to accomplish? Should it be dismissed, moved to the background, minimized... ?
|
|
|
|
|
The child dialog has to go back or get minimized. . .
|
|
|
|
|
Set the dialogs parent/owner to be the desktop window.
Without knowing much about your application, this behaviour seems rather confusing.

hm let me see,
i'm not an expert on this, but i'd say that you must create a program that is loaded at windows start (or session start - search for the keys in the registry), and that could (or not) have an icon in the system tray...
if you like, you could loook on code project for articles on the subject, i'm quite sure it has already been treated...
see u

The term "background application" is a holdover from the days of Unix and DOS (see TSR). It is meaningless within Windows because of its multitasking capabilities.
That said, what exactly is it that you are trying to accomplish?

I want to do for my parents an app which will log to file every application which run on it. My parents have an office - they want to prevent from using chattin' tools in it so they asked me. It have to work in background, otherwise it can be easily closed what will cause stopping of logging.

Thanks, that makes more sense!
Unless you are one with the OS, I don't not believe there is a foolproof way of keeping someone from shutting down your application if they really want it shut down. For the most part, this sort of application works great for the (semi) honest person. If a person is a guru and is determined to play a game, IM, etc, they will find a way around such barriers.
I've run into some tough spyware issues in the past but the one that impressed me most was comprised of two applications. From my observations, it appeared as though each was programmed to (once per second?) watch out for the other so that if one was shut down, the other would start it back up and vice-versa. Given that you can only shut down one application at a time via Task Manager (I'm sure there are other utilities out there that allow this), there was no way for me to shut them down at the same time. After about 45 minutes of trying everything I could think of, I finally rid the machine of the spyware. The guy whose machine I was working on was in awe/disbelief at how deep things could get in regards to spyware and the like. I think a bit of his naivety was removed that day.
What OS are we talking about here? If it is at least Windows 2000, you could put some policies in place that would lock the OS down pretty well. Policies/permissions are a very underutilized feature in my opinion. You can uninstall all but the necessary applications, keep other applications from being installed, restrict access to the CD and floppy drives, etc. All this can be done without an ounce of code.

I'm using here win[sh*t]98... and I want to write an app, you can ask why. Here's the answer: I want to practise my programming skills and.. this app will work in my parents office - they just want to have a proof if some1 is using chattin' app like MSN, ICQ etc., also this app will log every WWW title to the file - than we will know what was she/he doing and when. Do you know how to help me?
I'm going now - be back tomorrow -.- I'm from europe! It's 18:26 now thought... have to go to home and make my homeworks [I'm just 18years-old.. hah!]. Keep posting! I'll be back tomorrow and I'll read everything !

An admiral goal.

Some of these chat-type programs communicate on a specific port. If you can configure the firewall to block those ports, problem solved.

This would require the creation of a Browser Helper Object (BHO).

I ran into this with the Xupiter Spyware/Malware or whatever that CRAP was.
Only it had THREE programs doing this.
My trick was to stop one and have an explorer window OPEN to the folder where the EXE file was located. Once stopping it, I immediately deleted the EXE file.
Then I went onto the next one.
There were some DLLs loaded by IE and locked in memory that were a little tricker, and they resurrected one or two of the EXE files.
So.... I wrote a custom tool that has a file browser.
Any file I select gets added to the 'delete at restart' of Windows.
So, I added a bunch of the DLL files from Xupiter to this kill list, and the EXE files.
When I rebooted, it was mostly gone, then it was some manual cleanup of the registry.
Have not seen it since.

Good idea.

What do you mean by a Residential Application? If you clarify that it may be possible to give you a useful answer.

Windows NT Service should do the trick.
