If you try to select a font for CDialog object for example, that font has to be installed... as far as I know ....

Hi,
I am looking for a way to modify the name of files in a directory.
I know I can to that in Windows Explorer file by file.
I want to get an automated way because I have over 500 files to rename.
Thanks,
Claude

Have you tried SHFileOperation()?

Correct, but perhaps in conjunction with FindFirst and FindNext, this could be done programmatically. Especially if all the files are in the same directory.
As an alternative, if the file names follow some pattern, maybe you could generate a batch file with a series of RENAME commands and then run it from a DOS window. I have done this in the past with some success.

 While this might have been acceptable back in the days of DOS and 16-bit Windows, it's certainly considered antiquated by today's standards. And creating a batch file to do it is even more scary.
A simple call to SHFileOperation() is all that's needed to rename multiple files.

Hi
Can any body help me out i am using GetLocaleInfo() function to get the current locale setting when my project is running with explorer i am getting different results and when my project is running with IIS then it is giving different results i don't why.
I have set the current locale of my system to German (German).
Now, in this locale decimal symbol is comma(,) and digit grouping symbol is dot(.). when i use GetLocaleInfo to get the current (decimal symbol)/(digit grouping symbol) from my custom application i get ,/. respectively but when the program is running in IIS workspace it return ./, Both IIS server and the custom application are on same machine , and i ensure that regional setting is the German (German) through control panel and also the iexplorer locale is German (German)
i am using the following code segment....
int rslt;
TCHAR szDecimal[2], szThousand[2];
rslt = GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SDECIMAL, szDecimal, 2);
rslt = GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_STHOUSAND, szThousand, 2);
can any body help me out.....

Hi,
I saw in vc++ 6.0 editor
1. Show unicode control characters
2. Insert unicode control characters
these two menu when will click the right button within the any properties dialog caption control (e.g., check box -> right click -> properties -> properties dialog -> caption -> right click, see the last two menu)
Normallay these are disabled condition, how do enable? and what is the use?
Your suggestions are alway welcome......
Regards,
Inbha.

I expected that when you use clipped areas in a Device Context via function SelectClipRgn it would work the same way for printers, but it doesn't. Print Preview and Print modes do not understand clipping, and just as you call SelectClipRgn for the Preview or Printing nothing will be drawn within the clipped area. But then how do i implement clipped printing?

write a code to load bitmap and when we select option of
SAVE AS then in save as type there are option like 24-bit,256,16,monochrome etc(similar to MSPAINT option).
|
|
|
|
|
If you are wanting to know how to save / load bitmaps, you can find that out fairly simply, or look at
CxImage (search on CP).
But it sounds like you want to know how to customise the File Save dialog...
I would look at Rob Manderson's Image Preview Dialog[^], or Hans Dietrich's XFileDialog - Customizing CFileDialog[^] articles for examples.
Both of them are good resources.
Or you could look at most articles in the Dialogs - Common Dialogs[^] section on CodeProject...
Good luck,
Iain.

Hi,
I´m writing on an application that is "small" but with several classes with their own header file...
To avoid having to much files around I have written all the code in the header files...i.e. class declarations, function declarations and definitions etc.
(I have read several places that it doesn´t really matter)
This is probably bad code-writing, but is there any drawback to this?
Do the compiler treat code in the .h file differenly?
Is there code that cannot be written in the header file?
(sorry if this is a stupid question, but still I feel like a beginner in this)

One drawback, if you change someting in one header all have to be recompiled. If you implement in cpp files this wont happen.
Also "edit and continue" in debugging mode cant work properly. (?)
Dont do this, stupid
Try this @ home. (B&B)

In general, I think everyone will agree that header files should be used for declarations, and source files for definitions. Actually, sometimes you won't be able to do without source files. For example for static variables, for initialization of global variables, etc etc

why would you like to reduce the number of files ? to have only one that is about 80Kb weight ??? 
wow, good luck ! lol
well, in my case, i prefer having several file (one header associated with a module - .cpp), where each module implements a logical section.
Well, you should not be so strict either. For example, if you have a set of functions that are about to represent some Exceptions of your own in your program, you can put them in the same file, including also the functions implementation if they are writing on few lines.
Of course, this is a suggestion, you can do whatever you like, but i also think that if most of experienced programmers separate the actual instructions from declarations, they do have some reasons...
doneirik wrote:

actually, .h files are not compiled. The #include directive tells the pre-processor to copy the content of the .h file where such instruction is written in a file.
doneirik wrote:

Yep, affirmative !!
A header can contain :
- named namespaces (namespace N { /*...*/ });
- Types definitions (struct Point { int x, y; };)
- Templates declarations (template<class T> class Z;)
- Templates definitions (template<class T> class V { /*...*/ };)
- Functions declarations (extern int strlen(const char*);)
- inline functions definitions (inline char get(char* p) { return *p++; })
- Datas declarations (extern int a;)
- Constants definitions (const float pi = 3.141593;)
- Enumerations (enum Light { red, yellow, green };)
- Names declarations (class Matrix)
- Inclusion directives (#include <algorithm>)
- Macros definitions (#define VERSION 12)
- Conditional compilation directives (#ifdef _cplusplus)
- Comments (/* End of file */)
In the other hand, a header might never contain :
- Ordinary functions definitions (char get(char* p) { return *p++; })
- Datas definitions (int a)
- Arrays definitions (short tbl[] = {1, 2, 3};)
- Non-named namespaces (namespace { /*...*/ })
- Exported templates definitions (export template<class T> f(T t) { /*...*/ })
Moreover, Mr Stroustrup tells us in it famous book "The C++ Language" the following advices :
- Use headers to represent interfaces and to emphasize the logical structure;
- A header file must be included in a source file that implements its functions;
- Do not define global entities with the same name but not the same meaning within different units of translation (.cpp source files);
- Avoid writing non-inline function definitions inside headers;
- Use #include directive only in global scope and in namespaces;
- Never include incomplete declarations;
- Use made safe inclusions;
- Include C headers inside namespaces to avoid global names;
- Headers should be autonomous
- You may distinguish user interfaces from implementation functions interfaces;
- You may distinguish average users' interfaces from expert users' interfaces;
- Avoid non-local objects that need to be initialised with the execution, when the code have to be included in a program written in another language.

Just reorg your directories and put arrange the files that way. The only implementation I put in header files is 1-line returns and/or single "set" functions.
At least I'm not as bad as some people I know, they have a seperate cpp file for every function in the header! My rule is, break out another cpp if your function is 30-ish lines or longer, just for clarity. (although there should be very few cases where you need such a big function)

how do i use CreateDialogIndirect to create a dialog box?
how can the DLGTEMPLATEEX be used to retrieve /specify the properties of an existing dialog box?
and how is the callback function DialogProc to b used?

Right, it only takes two, which is what you have. SetupDiGetClassDevsEx() does take seven parameters, however, which you also have. Please provide the error verbatim from the compiler.
Unless you are just looking for something extra to do, there is no reason to respond to all of your posts with the name of the header files that have been included. Using < and > correctly will suffice.
