UTF8 to Unicode conversion Sivaji13-Jul-04 23:25 Sivaji 13-Jul-04 23:25  Hi I am reading text from UTF8 text file. I want to convert text to unicode to display in textbox.Pls help anyone ASAP. Thanks My main .cpp file is getting too big sweep12313-Jul-04 22:58 sweep123 13-Jul-04 22:58  My main .cpp file is getting too big. I tried to create a new file to place all new functions to the main class, but then run into compiler errors. Are they a simple way of splitting up a large file into several smaller files and not running into the mess as to what headers to include. I thought that Visual Studio would have managed this when I add new funtions (via the IDE) but No! Typical error c:\My_Example\My_ExampleDlg.h(42): error C2065: 'IDD_MY_EXAMPLE_DIALOG' : undeclared identifier But when I place all the functions into a single file all is OK.

It also uses data structures from another project, so could be quite large. Question do you realy want to take this on? All I want to do is have the main Main.cpp file split into several smaller files - just to make it easy the edit/manage.

I have exactly the same problem! Any assistance greatly received Re: My main .cpp file is getting too big sweep12311-Oct-04 6:17 sweep123 11-Oct-04 6:17  I did manage to split my program into several files. I moved pocedures into another C++ file and included all the header files that the main program had (then started to remove what I could). All you need to do is Add New file to project then move the procedures that you want to place in this new file (No header file required). Then just place at the top of the file the #includes that the MAINDlg.H file has - may not need them all. No need to do anything else with the project. Hope this helps. C++ - A scenario - any recommendations please? Chua Wen Ching13-Jul-04 22:50 Chua Wen Ching 13-Jul-04 22:50  Hi there, I had a very tough scenario, and seriously i had no idea how to solve this. It will be long as i tried to explain in detail. I need a good solution based on those who coded c++ and writes dlls. Before this: There is a dll called by UtilityA.dll. It was called by a UtilityMain SDK. In UtilityA.dll, it actually calls a 3rd party dll called 3rdPartyv1.dll. The main reason of UtilityA.dll existence is to write a wrapper and simplies stuff. So the UtilityMain SDK can call it easier. No idea why it is done like that. Now: We had released a new hardware. The new hardwares uses the new 3rdPartyv2.dll. There are 19 functions inside the 3rdPartyv2.dll if compare to 3rdPartyv1.dll which only contains 15 functions. But the names are roughly the same, but in some functions, there are additional paremeters and return different data types. I need to write a wrapper for the 3rdPartyv2.dll that will called the new UtilityB.dll instead of UtilityA.dll with additional new 4 functions (19 - 15). So my SDK can called my UtilityB.dll. The problems now: 1) We had many SDKs, around 20 versions. On different companies and countries. 2) If we use a different wrappers name, we had to recompile the SDK. Which is kind of tough! 3) If we stick the same called UtilityA.dll, but just say in future, the hardware already more advanced and a different modal. We can't just use UtilityA.dll again and again. Real example: Reader - Utility435.dll which calls the MXM435.dll which MXM435 is a reader device. Now there is a new model called MXM467 reader. If i use back the same Utility435.dll, which is misleading, does not represent anything. No choice the previous coders, never think of this problem. 4) There are many applications already being developed in VB6. We can't ask all the clients to recompile their apps because the SDK had been modified. Very very tough deployment. How can we solve this scenario? Now is between the wrapper and the SDK. Is there anyway to write a plugin to the SDK. As what i know from C#, you can write a library that exposes some interfaces, so you can write a plugin to it. But now the SDK had existed, and it was badly done i suppose. I not even sure it can have plugin enabled. I was hoping to write something, that can add on to the SDK on run time or dynamically without recompiling any existing codes, and won't affect any parties. But of course I had to change the new 3rdPartyv2.dll and the new wrapper. Just don't want to recompile the SDK. 3rdPartyv1.dll and 3rdPartyv2.dll - C dlls. UtilityA.dll and UtilityB.dll -> C++ dlls. SDK - C++ Application layer - VB6, C++, ASP Any help please? Thanks.

However to find reasonable solution I think we need to clarify something. You said that you don't want to change SDK, but how do you expect users to access new function in 3rdPatry.dll? Unless of course those functions for Utility.dll use only and if this is a case then I don't see problem anymore. problem in movement of the group control maxsteel13-Jul-04 22:19 maxsteel 13-Jul-04 22:19  hi, i have a group control on a dialog box. this group control has two edit boxes. i have written code to resize the dialog box and all the controls along with it. the problem is that when i move the group control, the controls within it move twice, once with the group control and the next time individually. this is causing the movement of the edit boxes to be seen twice causing some kind of flickering? also can u tell me how i can move all the controls within the dialog box simultaneously. right now i move each of the controls along with the resizing of the dialog box but there is some time lag in the movement of each of the controls. can any one tell me a solution?
