Start here. Use RT_STRING instead of RT_RCDATA.

It would help to specify all of your requirements in your initial post. Roll eyes | :rolleyes:

i have to read some strings in run time from a .txt/.xls file...these files can be edited by user at any time with out altering the code.....

then, why reimporting them in your resources ?
why just not using those files (.txt/.xls) as external resources ?

but i think searching from .txt/.xls file for each string will take more time....and i have tons of strings to store...

and how do you work with your resource string tables ? Confused | :confused:

do the external files having always the same number of string (never new ones) ?
or is it possible that some strings can be added/removed ?

not really, but i was just curious, as it seemed to me that reading files directly could be more simple. but i may be wrong...

   You do not search at runtime, you bring them all into memory at startup. Even if you had 32767 strings with a length of 64 each, that would only require 2MB of memory - not a lot in today's world especially when it is only needs to be managed once at startup and once at shutdown.

If you design the file correctly, each string has a specific index, you store offsets into the file for each index, place the index at the start of the file, and you store the strings with their terminating NUL characters.

   So at startup, you memory-map the strings file, read the index to determine the start of each (indexed) string, and since it contains its terminating NUL, you can use normal string-handling code to copy the strings where needed for display just by starting the copy operation from its offset using the address of the view of the MM file.

   This would require a separate app to edit the strings file, but it would be worth it, IMHO.

   Peace!

   Then details of the indexing used (how you locate specific strings in the file), copy methods used (how you get the string from file to memory), and the flags used when you open the file (can you MMap on CE) would be helpful.

   Also, please define the performance you are looking for, and what you mean by "too slow". If it is taking 250ms to load and show a string, that may be OK for a CE device. Taking 5 seconds is not.

   Peace!

Hello,

I use C++ in Visual Studio 98, and I have a question about the behavior of the interface.
I don't understand why for some home C++ projects, the available methods are shown when I type the name of an object, and for others home C++ projects nothing is shown.

Here is an example of what i'm expecting :

Do you know how to enable this feature in VSC++98 ?

Thanks,

Fred

ahhh, the misteries of IntelliSense Big Grin | :-D

Ctrl+SpaceBar should solve your problem, unless your function is out of the current scope...

Delete the project's temporary files such as .ncb, .clw, .aps, .opt, .plg, etc. Open the project again and those that are necessary will get rebuilt.

Visual C++ 6.0 only processes files that are actually part of the project. The resulting IntelliSense information is placed in an .ncb file to save startup costs. In addition, VC uses a few pre-parsed .ncb files installed with Visual Studio (CRT.NCB, MFCATL.NCB, WIN32.NCB) for libraries supplied with it, and the Windows headers that came with VS6. The Windows IntelliSense information is now rather out of date.

I believe this problem continued in VS 2002 and 2003. VS2005 now actually processes included headers, so the information reflects the actual state of the source code.

Anyway, to get the methods of an object included, you need to include the corresponding header file in your project.

Visual Studio 6.0 also seems to have some threading gremlins which can cause the popup not to display, even though the status bar says 'Type the character following...' (or whatever the message is, I can't recall at the moment) as it normally does when the method picker is displayed.

Stability. What an interesting concept. -- Chris Maunder

hi all,

Is there any way to convert the existing code(Vc++) to a webbased program??

You could probably convert it to an ActiveX control.

My advice is to do it right, and (assuming you're writing a .Net 2.0 site) convert it manually to C#. If you're even halfway talented as a programmer, this shouldn't be a hard task.
