Well, there's no such thing called "registry cleaning" and most of those software are nothing more than a pile of crap.
As David clearly stated, how could anyone else other than the author (the app who wrote the key and values) possibly know that the key is "invalid" or "unwanted"? And there is no such algorithm available which decides this. If you need one, you must think of all the possibilities and devise your own algorithm.
A slight mistake that a registry cleaning software can cause devastating results. May be on operating systems like Win95 or 98, you could possibly get a very marginal benefit by deleting the registry keys that are unused. But with more recent versions, the OS is smart enough and you will almost get NO benefit just be deleting some registry keys that aren't used. If you have a different opinion (with some kind of proof or benchmarking tests done), I'll be interested in hearing from you.
After all, if you don't know much about how and what kind of cleaning operations should be performed on the registry, you must not be writing such a software.

While it's not an answer to your question, take a look at this article. It shows how to remove registry entries that are known to be bad. That should clue you in as to why you can't just willy nilly remove registry entries without knowing what they are for.

I have created a SDI application with CFormView in VS 2005, vc++, MFC. I placed listctrl, a group box, and a couple of buttons and textboxes in the group box. I am setting the list ctrl and group box posisions at runtime using SetWindowPos(). The list control and the group box sets as per my x,y values. But the control which i have palced in the group box are not set with the group box. They are there, where i have placed them statically. I want all the control placed in the group box to be set as i change the pos of the group box. Is it possible. If yes where am i doing wrong.
Thank you.

A groupbox is just a control like any other (with a big hole in it). Just because you place controls inside of it in the dialog editor it won't be the parent of those controls. So as far as i know you can't move the controls visibly inside the gorup box by just moving the group box itself, you have to move the controls individually inside the group box. You could try doing 4 things i think:
1. Move the controls individually - not too nice but works
2. Put the controls which are inside of the groupbox on some custom-made panel and move that one around, so you only have to move the groupbox and the panel representing its inside. - a bit complicated, not too nice, but works
3. Put the groupbox and the controls visually inside it onto a panel (like a child dialog for exmaple) and move that one around - a bit less complicated than 2. but still not nice
4. Write some helper class that walks thorough the controls which are inside the gorup box and moves them around, maybe a class inherited from the groupbox class. - I'd chose this one, you are still moving around the controls individually but you get a reusable way to do so. You would need for example an array into which you'd place the controls that need to be moved simulteniously, you could also make a method for it that collects the controls inside the group box by checking their positions.
I hope this all helps,
good luck.

Thank you.
I just tried to place a tab control and put some controls on it. Even the tab control is not controling the controls. When i am moving the tabcontrol the controls placed on it are not moving. I tried cut paste on tab control also.
Can u help me in this!

The tab control is the same as the group box regarding this issue. If you want to change tabs you will either have to write yourself your own tabpage-changing mechanism or look for one, i am sure there are such already written and useable solutions for that here (or just use google).

You can convert the bitmap to a JPG and then...

If you can provide some code or example as to how ro convert it would of great help.

If you are using MFC, you could use CImage::Save() with ImageFormatJPEG or ImageFormatGIF as the guidFileType field.

I am able to save it in JPG format but the size of the file is somewhere around 150KB. Is there any way I can Optimize the size to somewhere below 100KB as it needs to be sent to the server for real time monitoring.
Thanks In Advance

Use GDI+ to save to JPG. Once you have a HBITMAP containing the screenshot do Something like this (can't remember the correct objects/methods now so you will have to look them up, but it generally goes something like this):
Gdiplus::Bitmap Img;
Img.Attach(hbitmap_screenshot);
Img.Save(path_to_save_to, Gdiplus::ImageFormatJPEG);
Img.Detach();

you can use CxImage class.CxImage is a C++ class to load, save, display, transform BMP, JPEG, GIF, PNG, TIFF, MNG, ICO, PCX, TGA, WMF, WBMP, JBG, J2K images

Hi,
I am moving project from MS Visual studio 7.1 to 8.0, in this I am facing problems in building DLL. Many projects get build successfully but while building one project compiler throws error as
"c:\program files\microsoft visual studio 8\vc\atlmfc\include\afx.h(24) : fatal error C1189: #error : Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD[d]"
I didn't get how to solve this problem.
compiler throws this error only when building debug DLL and not in release DLL.
Please help me......

I don't know VS8.0, we're still using 7.x, but to me it looks like you are trying to link to MFC staticly but to CRT dinamycally and it doesn't like that. Does that make sense?
> The problem with computers is that they do what you tell them to do and not what you want them to do. <
|
|
|
|
|
But in case of release build compiler doesn't gives errors .....
What reason would be behind this....??
|
|

You have different settings for different targets? You can setup things so your debug builds use dynamic and your release builds use static linking or the other way around. Sometimes it happens that someone makes changes to the project settings but forgets to make those to all targets and only applies them to the currently set one and then when others try to build the release, bang, problem. I know it has happened to us a few times too, like i added additional include folders to the debug target but forgot to add them to the release target so when others tried to build the release, multiple "no such file or directoy"s. Fun.

how to achieve it ?
i tried static variable , extern could not solve my problem ..

Your requirements define a global variable.

With no luck, I suppose...

Actually extern will solve your problem, for instance, declare it extern in a common included header, say commonheader.h:
extern int g_iMyCounter;
Then define it inside only one source file, for instance
int g_iMyCounter;
Finally include commonheader.h in whathever source file needs such variable, for instance
#include "commonheader.h"
int incrementMyCounter()
{
return ++g_iMyCounter;
}

The purpoue of extern is to solve this situation. Check out this link[^].
Well, I recommend to go for a singleton class[^] with name CGlobalData [according to your choice], and make all your required global variables as its members. Then you could access your singleton class from all cpp files and can access the global data as well. Its more object oriented and more easier to maintain than global variables.

Jijo.
