Hello,
I am developing a software of Arabic version using Visual C++.
I need to get the glyph outline of a string.
I used GetGlyphOutline() to do this.
However, I can't get the correct outline.
The arabic's char changed according to the next char. (to make them link together)
The following URL shows the different.
http://home.kimo.com.tw/chcnjg/index.html
The above block shows the correct result.
The below block shows the result I got.
Does anyone know how to solve this problem?
Or how to find the related data?
I try to solve this problem for a long time and failed.
This problem really made me crazy.
If you have any information, please tell me.
Thank you very much.
Best Regards,
chcnjg

Hello,
I have been working with Visual Studio .NET for about a year but I wanted to add Visual Studio 6 on my computer. Will a problem arise if I install it?

I downloaded a code that requires to compile it with version.lib.
// Remember: You must link version.lib to the project for this class to work !!
I am using VC++6. Can any body tell me how to do this?
Any help is greatly appreciated

a simple way (but not necessarily portable to non-MS systems (I only use VC++ versions) is to put a line like this in stdafx.cpp
#pragma comment(lib,"version.lib")
which will put a comment in the STDAFX.OBJ file to tell the linker to search that library.

Downloader and Install files from the WEB (Like the Windows Updates)
Hi everybody.
I'm trying to create a web application with C#.net or C++ like the (windows updates from Microsoft) to let the customer of our company download automatically our executables files from the web and also let the web app automatically the install those files on their computers.
If somebody has any idea of how to do it or any source code about it, I’d appreciate.
Thanks

I would suggest that you abandon the idea of doing it from your browser (the way that win update does). Just a few of the reasons that this is a bad idea are:
* Most network admins have disabled installation of the applet you would need for this.
* In order for the applet to install securely you would need to purchase a certificate from a certificate authority (a fairly expensive proposition considering the alternative is free)
* C++ is completely incapable of doing this unless you develop it using a plug-in (which is a very difficult way of doing such a simple thing). C# and Java are both too limited when ran as applets to make the possibly needed registry changes.
* Even if you got past all of this, it is still far more inconvienent for the user to go find your download section of the website than it is for them to select an option in the menu of the prog they are already using.
* An application can be setup to automaticaly check for newer versions without the user needing to bother with it.
The better way to handle this problem is by using either C# or C++ to write a seperate app that simply downloads the files into the correct directories and makes any registry changes needed.
This application will follow this basic program flow:
1. Check FTP server for newer version of the installation file. A good way to do this is to use a specific file naming convention and comparing that to a set of variables in the main app (in .NET apps this is already availible through the App object). These can be sent to the updater app via the command line, DDE or OLE (whatever you are most comfortable with).
2. If newer file is found, then download.
3. After download completes close any running instances of the main app and run the install app you just downloaded.
If you don't want the user to see an installation wizard each update...you could make your own installation routines that does the same things as an instalation wizard but this will be more difficult for you and only save the user a few occasional clicks. Technically, you should have it first uninstall the old version before installing the new but if you don't do that, it shouldn't cause too many problems as long as you don't register the prog each update. Depending on which installer you are using their should be some way to set that.

I have a program that needs some way of getting a generic resource and loading it as a normal file. I would prefare to work with io streams, but I don't have too. I know how to load an image or a cursor or an icon, but they just return HBITMAP or HCURSOR or HICON.
Thank you in advanced

Check out the FindResource(), LoadResource(), and LockResource() APIs, using those you can get the raw data of a resource.

Hi all:
I am still learning c++, so I will try to describe my problem and what I am try to do the best I can.
The basis of my program is to take data from the Serial I/O Port into a character array and analyze it and do all kinds of stuff with it. Right now what I am trying to do is take a byte (I am working with whole numbers, so my byte would = 2 characters) and compare it against a table of possible matches and if the byte matches, go to the function that corresponds with that byte.
I'll give an example here:
Lets say the whole number integer is 48. Now I want to take 48 and compare it against a list of commands (00 to 99) and if one matches go to the routine of that matching number. so when it compared 48 against 48 in the table it would then call the cmd48() function and go from there.
I hope I have been as clear as possible, so that you can understand what it is I am trying to do.
NOTE: I dont think a switch-Break statement would work since it only checks 1 character and obviously I am not working with only 1 character, so I dont know anything else to use.
Thanks

Your best bet would be to use function pointers in a lookup table. Assuming all the functions return void and take no parameters...
void (*functions[])() = { cmd0, cmd1, cmd2, cmd3 };
...
char string[3] = "48";
int number = atoi(string);
if (number >= 0 && number <= 3)
{
(*functions[number])();
}Just make sure that you never index your array out of bounds, or you'll have huge problems, and the errors probably won't make any sense. The first element in the array will be if a 0 is received, the second element for a 1 received etc.
Hope this helps
PS. Look up a textbook on function pointers if you're not sure how they work.

For starters, you can remove the C$ and ADMIN$ shares on that machine. You can also go into the LAN Properties dialog and uncheck File and Printer Sharing.

This is actually impossible. Net cards (or any other piece of hardware) do not have the ability to create files (yes drives can make files but this is actually because the OS tells them how to). Fortunately any OS that is capable of networking also includes programs to convert data sent over the network into files (this is called an abstraction layer) that makes it as simple to do as saving any other file. This means that to save a file in a shared network directory all you need to do is save it to a network path. The source directory must have read permissions and the destination directory must have write permissions and be shared on the network as such. Different OSes have different ways to set these options. After you have the permissions setup you can use any file operation you want to do this. For example, to copy the file C:\dat.txt to //sysb/inc/dat.txt you could use the API function CopyFile like so:
CopyFile("c:\dat.txt", "//sysB/inc/dat.txt", FALSE);
sysb would be the name of the other computer and inc would be the shared directory.

Dear All,
I am developing a Win32 Application in Windows API VC6.0, I need to use an MS Access 2000 Database to connect to. Reading some of the Articles on codeproject site, but could not decide what is the best to use:
ADO
COM
DAO
ODBC
My Appliction need to run smootly on Windows 9x, 2k and XP?
=======================
Just reading the Article: Express OLE DB Library: An ideal data access solution for C++ By Ghanshyam Naik, I decided to use ODBC for my project.
Any help is appreciate to connect to MS ACCESS using ODBC (NOT MFC) or using MFC Classes in Win32 and Win API Programming.

"Best" is a subjective term. It all depends on what you are after as to what technology you would use. How big is the database? How many connections are you expecting to support? Can the database be accessed by more than one connection at a time? How many transactions-per-second do you expect? Does the database need to be backed up while in use? This is not an all-inclusive list of questions.

You want to connect to an Access database without using MFC, but you want help with MFC. Is that correct?

Dear David Crow,
I would like to use ODBC, Win API in a Win32 Application, my Database is just a catalog. Select ProductID in listbox and then Show Other Information in a Static text windows.
I found this Interesting Article but it is MFC, I want the same thing in Win API.

I posted my code to the author, I will appreciate if you have a look at.
Thanks

Under the odbcsqlconnect.asp I copied this sample code, but it give me 9 Errors. Some others do not have samples. I get a lot of errors including any SQLxx.h files.
SQLHENV henv;
SQLHDBC hdbc;
SQLHSTMT hstmt;
SQLRETURN retcode;
/*Allocate environment handle */
retcode = SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv);
if (retcode == SQL_SUCCESS || retcode == SQL_SUCCESS_WITH_INFO) {
/* Set the ODBC version environment attribute */
retcode = SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0);
if (retcode == SQL_SUCCESS || retcode == SQL_SUCCESS_WITH_INFO) {
/* Allocate connection handle */
retcode = SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);
if (retcode == SQL_SUCCESS || retcode == SQL_SUCCESS_WITH_INFO) {
/* Set login timeout to 5 seconds. */
SQLSetConnectAttr(hdbc, (void*)SQL_LOGIN_TIMEOUT, 5, 0);
/* Connect to data source */
retcode = SQLConnect(hdbc, (SQLCHAR*) "TEST", SQL_NTS,

How are you using this code snippet? What other .h files have you included?
