App Express to generate OCX

Hi, Get message "Note: You will need the OCX Control Development Kit to build this application". Where do I get that? Also, compiling code gives following errors sc test_ocx.cpp -mn -C -WA -S -3 -a8 -c -gf -otest_ocx.obj sc test_ctl.cpp -mn -C -WA -S -3 -a8 -c -gf -otest_ctl.obj Error: I:\TEST_OCX\test_ctl.cpp(141): need explicit cast for function parameter 3 to get I:\TEST_OCX\test_ctl.cpp(141): from: char const * I:\TEST_OCX\test_ctl.cpp(141): to : unsigned short const * Error: I:\TEST_OCX\test_ctl.cpp(155): need explicit cast for function parameter 1 to get I:\TEST_OCX\test_ctl.cpp(155): from: char const * I:\TEST_OCX\test_ctl.cpp(155): to : unsigned short const * Lines Processed: 332672 Errors: 2 Warnings: 0 Build failed It doesn't help to relax type checking. Thanks. TC

1. Where is that message coming from? 2. I'm guessing, not seeing your source code, that you're passing a char string where a wchar_t string is expected. -Walter TC wrote in message <3b5aa0f5.16146510@news.digitalmars.com>... >Hi, > >Get message "Note: You will need the OCX Control Development Kit to build this application".

I guess this is because of _szLicString declared as "static const char" instead of "static const TCHAR" and _szLicFileName declared wrongly like that. I have manually changed it a couple of times. Once a complete run throught the IDDE has been done I guess this problem will be resolved... <Sorry> On the OCX Control Development Kit... Try to compile the project...

Hi, Got this after changing as suggested. sc test_ctl.cpp -cpp -Jm -p -J -mn -C -WA -S -3 -a8 -c -gf -otest_ctl.obj Error: I:\test_ocx\test_ctl.cpp(141): need explicit cast for function parameter 3 to get I:\test_ocx\test_ctl.cpp(141): from: char const * I:\test_ocx\test_ctl.cpp(141): to : unsigned short const * Error: I:\test_ocx\test_ctl.cpp(155): need explicit cast for function parameter 1 to get I:\test_ocx\test_ctl.cpp(155): from: char const * I:\test_ocx\test_ctl.cpp(155): to : unsigned short const * Lines Processed: 166485 Errors: 2 Warnings: 0 Build failed Again relaxing type checking and setting Char behaviour to unsigned doesn't help.

I think you might have to use WCHAR instead of TCHAR... sorry...

Relaxed type checkiing won't help you as a pointer to a 'byte' sized area is too different from a pointer to a 'word' sized area...
