Thanks for your help!
Actually i hoped that i am right, but i have expected that! What i try to do is the following:
I have written a patch which injects some code into the kernel32.dll (Win98) which should load a specific .dll evertime the kernel32.dll is loaded. I have switched the original kernel32.dll with a boot disk. To get a little bit more specific: i have changed the adresse of the entry-point function, so it jumps to my code, where a specific dll should be loaded, and then jump back to the "real" entry-point-function!
The strange but funny thing is, that windows98 starts up as if there is no manipulation in its kernel32.dll! I also have changed the code into something that makes no sense to see what happens, and yes, after that i have gotten a beautiful blue screen! The code to load the additional dll within the kernel32.dll is absolutely correct (that's what i think it is)! I don't have an idea why i doesn't load the dll!
Any ideas ?
Thanks in advance!

With a tool like dependencywalker for example I can see the function exports of a dll. Is it possible to figure out the parameter list of such an export function (certainly not the names, but perhaps the number and the data types) ?

if the names are decorated (they looks funny)
you may find out the parameterlist. but usualy they are not decorated and you have no chance.

Hi,
I have an MDI application with views derived from CHtmlView, and my problem is with Undo,Cut, and Copy menu items under the Edit menu, which is always found disabled. Can anyone tell me how can I enable those menu items when a selection is made in the view.
Thanks and Regards

Handle an ON_UPDATE_COMMAND_UI message for appropriate IDs (ID_EDIT_UNDO etc.)

Handle each menu item in your CHTMLView derived class like:
[...]
ON_COMMAND(ID_EDIT_CUT, OnEditCut)
ON_COMMAND(ID_EDIT_COPY, OnEditCopy)
ON_COMMAND(ID_EDIT_PASTE, OnEditPaste)
ON_COMMAND(ID_EDIT_SELECTALL, OnEditSelectAll)
[...]
Below is the implementation for each member function:
void CWebView::OnEditCut()
{
ExecWB(OLECMDID_CUT, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL);
}
void CWebView::OnEditCopy()
{
ExecWB(OLECMDID_COPY, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL);
}
void CWebView::OnEditPaste()
{
ExecWB(OLECMDID_PASTE, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL);
}
void CWebView::OnEditSelectAll()
{
ExecWB(OLECMDID_SELECTALL, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL);
}
I got this code from an article somewhere, but unfortunately, I can't find where the article is again. Anyway, this should help you out.
Happy Programming!

My application is in VC++ and it needs to notify the user [may be a message box] whenever there is a change in system password.
How can this be achieved? Is there any simple event registered with the system and handled in the application?
I searched on the web and got to know something about password filters and credential managers but those seem to non-trivial. Is there any other way by which my application can get to know the passwprd change?
This is an urgent requirement. If anybody could suggest something, it will be greatly appreciated!
thanx

Dear friends,
This problem is related to CRichEditCtrl. Actually i want to display my custom font in this control. My font requires right alignment. So i programatically changed the alignment to right as follows:
PARAFORMAT pf;
pf.cbSize = sizeof(PARAFORMAT);
pf.dwMask = PFM_ALIGNMENT;
pf.wAlignment = PFA_RIGHT;
SetParaFormat(pf);
As such everything works fine for me. But my font is displayed correctly if characters are fitted only in a single line of rich Edit Control. In case when my text needs to fit in multiple lines, i am having trouble. As such text is displayed correctly. But "next" line comes on top of existing line and previous line is moved to bottom. How can i change this default behaviour of rich edit control.
Actually my font is arabic font which needs to get typed from right to left (i.e "reverse" of default behaviour). But i am unable to "reverse" the order in which RichEdit inserts characters in new line.

I have a public __gc class named Zones. At program startup I want the program to read a data file, and dynamically invoke instances of Zones depending on how many are listed in the .dat file.
--Example of .dat file
[Zone1]
name=test1
loc=coords1
[Zone2]
name=test2
loc=coords2
[zone3]
name=test3
loc=coords3
I would like to create a filestream and streamreader, create an instance of the class Zones, input the first 4 lines of data (first and 4th are non-necessary), and then peek at the next line. If the peek != NULL, then loop back up to create a 2nd instance, etc etc etc until it gets to the end of the file which would be a blank line. Then I can perform calculations and find out which is the closest to me (according to my location coords from another class (public __gc class MyLoc)) and info like that.

Hello all,
I'm having a bizarre problem.
I created a setup for my program, using Installshield Express 5.
The program installs with no problems, and the required shortcuts are created.
Then, I make a QuickPatch for it, and install it. The QuickPatch replaces a single file - and works with no error - but it ruins the shortcuts!
More specifically, after I run it, the shortcuts point to "nothing" (an empty field), and fail to run (Windows displays an "Invalid parameter" error message box.
Any ideas??
Thanks in advance!

Hi,All
I am in this stiuation. I have a header file(foo.h) that is in a different directory. For instance, my project is under c:\test\, and foo.h is under c:\confuse\foo.h. I am trying to include foo.h into my project. And the way i do is as following:
#include "..\confuse\foo.h". The error message is
fatal error C1083: Cannot open include file: '..\confuse\foo.h': No such file or directory.
Could somebody tell me what can i do?
Thanks in advance.

try / instead of \
otherwise...make sure your files are in those actual directories and everything should work 
If not i'm as confused as you are

Take the Visual Studio path setting by
Tools menu > Option > Directory tab >
Then add the directory to the Include path list. Here in ur case "c:\confuse".
Then just use
#include "foo.h"

Jijo.

Tools > Options > Directory is a user setting. Only use this for system includes such as the Platform SDK. These settings are not carried along with the project, so anyone else working with the project will have to configure their IDE appropriately.
For projects, you should go to Project > Settings > C/C++ tab > Preprocessor category and add the directory to the Additional Directories setting. You'll need to do this for all configurations.
The Additional Directories setting is a comma-separated list of directories. You should specify the directory relative to the location of the project's .dsp file.
A layout I often use is
proj
+-inc
+-src
+-lib
+-bin
+-obj In this case, I put common include files in inc, my project files live in the root proj directory, so the Additional Directories field simply has inc in it.

Thanks, guys.
Mike, i am following your suggestion. Preprocesor category you metioned is C/C++ tab > Preprocessor definition? In the Preprocessor definition box, i have "WIN32,_DEBUG,_WINDOWS,_AFXDLL,_MBCS", how can i specify the directory relative to the location of the project's .dsp file?
Thank you very much.

You're looking at the wrong control.
The top control in the box is the Category drop-down, which currently reads General. You need to change that to Preprocessor.
You should then see a layout something like:
Category: [Preprocessor ][v] [Reset]
Preprocessor definitions:
[_DEBUG,WIN32,_CONSOLE,_MBCS ]
Undefined symbols: [ ] Undefine all symbols
[ ]
Additional include directories:
[ <edit this field> ] [ ] Ignore standard include paths
Project Options:
[ ] [ ] You should add the directory in the Additional include directories field - in your case, probably ..\confuse.

Thank you very much, Mike.
I just tried the way you showed me. However, i still get the same error.
After i added the directory and compiling it, there is a pop up dialog
"The project setting have changed since the last build. Would you like to rebuild the affected files?" I clicked YES.
In addition, in the file i need to include foo.h, i did both tries:
#include "..\confuse\foo.h"
or
#include "foo.h"
What do you think?

I agree with you mike.

hy, i have a sample program, in which i can grab bitmaps or avis from any webcam. now, what im trying to do is to measure the velocity of movements, like lets say the movement of a hand. so when you shake your hand in front of the webcam, the program should put out a factor between 1-4 1 for slow and 4 for fast. i tryed several things, like comparing 2 bitmaps every 200ms, etc. but it all didnt worked . and also performance is a big issue.
i compare the bitmap with bmpPicture.GetPixel(nW,nH) etc. so i need to compare every pixel. does anybody has an idea of how i can solve this problem? maby there is some code out there i can use, or a simpler approach?
thanx a lot!

I don't have code, but why don't you sample bands instead of the entire image? For example, if you had a 10 x 10 pixel image (using 10 here just to illustrate...) you could sample every 2 pixels and reduce by a factor of 2. (ie: 5 bands) Or, you could even sample every 5 bands and reduce by a factor of 5 (ie, you would have 2 samples - 10 /5 = 2...)
Was that clear??
You could even be really elegant and sample as per a comb filter at the Nyquist frequency!

hy,so you mean i should basically reduce the imagesize of the images i compare? but in the end i must compare pixels etc? i think youre right,
maby even black/white pictures will do the job. what do you mean with
"You could even be really elegant and sample as per a comb filter at the Nyquist frequency!"
?
thanx, greez

hmm you probably need to standardise the distance so you know that the hand is always i metre away from the camera say.
Then you probably could figure out the "width" and "height" of the view from 1 metre.
and then you can tell that 1 pixel at NxM res' corresponds to a set area.
then it comes down to figuring out when and where the motion started and when and where it finishes.
Sounds like a 3 year computer science project to me

3 years,oh my gosh!? i thought i could do this in an afternoon
but im convinced there is an easy approach! and remember, all i want is
relative velocity, not abolute. i just want to know if the hand moves slow or fast. so i was thinking about making every x ms a bitmap, and then compare them. lets say i wear a white t-shirt, and my hand is black. so when
i move the hand up and down i could detect, how many light or dark pixels are in lets say 4 zones of the bitmap. so i could detect the position of the hand, and with that also the velocity. i think i could do this in 2 days, what do you think??
