The .net runtime is redistributable free of charge with your app. other main interest is that large part of .net is open standard and supported on other platforms also. And .net runtime will comes with the OS, now-a-days or in near future......I guess so.

Ya, I also think so, but the point is WIN98 is 7 years old OS, and technology changes every day. I am talking about future releases of MS OS.

My apps are tested on Windows NT 4.0 to Windows Server 2003, provided I distribute mfc*.dll and msvcrt.dll with the app, as Mr. David says. Or you link MFC as static library in the project options.

I don't rely upon it, but it is very handy when it does work.

I need to insert text to Listbox with tab
Exemple
Text1 "TAB" Text2 "TAB" Text3
How can I do that?
|
|
|
|
|
Check the 'Use Tabstops' checkbox in the style tab of the list box properties.
Then give the text as "Text1\tText2\Text3"

I use ATL Com AppWizard(in embedded Visual C++) to create a signature capturing DLL, i successfully let user to sign on a given rectangle square box.
However,
i have a big problem when coming to capture the signature inside the rectangle and save it to bmp (or jpg) file. i get the following attached code and trying to compile it inside embedded Visual C++ 4.0, and it comes out this error:
"GetDIBits: undeclared identifier" ...
it seems like eVC++(or Pocket PC 2003 SDK) doesn't have this library or doesn't support this function...
is there anyway i can do it ? this problem has been struggling me for few days ...
thanks

Hi,
I have to convert a string which is representating a hex number (e.g. "FE34") into a string which displays the decimal number ("65076"). Because the length of number may be upto 1000 (byte array) I cannot use a sscanf/sprintf methods.
Any ideas how I can solve the problem?
Best Regards
Heiko

char *s = "FE34", ch;
double dwNUM = 0;
while(*s != NULL)
{
ch = (char)*s;
dwNUM *= 16;
switch(ch) {
case '0':
dwNUM += 0;
break;
case '1':
dwNUM += 1;
break;
case '2':
dwNUM += 2;
break;
case '3':
dwNUM += 3;
break;
case '4':
dwNUM += 4;
break;
case '5':
dwNUM += 5;
break;
case '6':
dwNUM += 6;
break;
case '7':
dwNUM += 7;
break;
case '8':
dwNUM += 8;
break;
case '9':
dwNUM += 9;
break;
case 'A':
dwNUM += 10;
break;
case 'B':
dwNUM += 11;
break;
case 'C':
dwNUM += 12;
break;
case 'D':
dwNUM += 13;
break;
case 'E':
dwNUM += 14;
break;
case 'F':
dwNUM += 15;
break;
default:
break;
}
s++;
}

Don't forget to uppercase the string or check for lowercase 'a' to 'f'

You don't need the large switch statement.
char *s = "FE34", ch;
double dwNUM = 0;
while (*s != NULL) {
ch = (char) *s;
dwNUM *= 16;
if ((ch > '0') && (ch <= '9'))
dwNum += (ch - '0');
else {
ch = tolower (ch);
if ((ch > 'a') && (ch <= 'f'))
dwNum += (ch - 'a' + 10);
}
s++;
}

yes, you are right, but I just made a small demo to show how to do, what he wants. Like your demo, which says:
if ((ch > 'a') && (ch <= 'f'))
instead of
if ((ch ><code>=</code> 'a') && (ch <= 'f'))
 ;)

Thanks for your suggestion. But for very long hex strings (e.g. "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA") the floating point value is truncated. So if I want to switch vom DEC to HEX and vica versa I get other values. Am I right?
