    - VCCodeFunction adding override keyword We are using the visual studio automation from an external application to write classes with functions in them in .cpp and .h files. With the VCCodeFunction I can see no way to add the override keyword after the funtion. Can anybody please point me to a way to do this. (Using the VCCodeFunction we can set access rights parameters, whether it is virtual etc.) Thanks Tiaan Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - wide character (unicode) and multi-byte character Thanks Saravanan ! Previously, I think multibyte character is a specific encoding (codepage). But after discussion with you, I think I am wrong. Multibyte character on Windows is a general term which is used for representing character which could be stored in more than one byte. And several encoding (codepage), like UTF-8, ANSI, ... could be called as multibyte character. Is my understanding correct If my understanding is correct, I am wondering the differences between multi-byte and wide character I think they are both characters which are represented by more than one bytes. Why on Windows they are distinguished regards, George Saravanan V V wrote: Hi Please check the link . If not the content is placed below. Like any application, DI needs to know which "codepage" to use when processing data. Codepages are character encoding tables. Codepages are necessary because ultimately, all software operates with sequences of bytes, not the actual letters or numbers that you see on a computer screen. Operating systems and other software applications use codepages to map sequences of bytes to specific characters. Those characters can be single-byte characters such as English or French or multi-byte characters such as Korean or Chinese. Do not assume each language has it's own codepage. Codepages provide a mapping for a specific set of characters, and in the case of codepage MS1252, many languages such as English, French, German, and Swahili all use the same codepage. This is possible because they share many characters such as "a", "b", "c", etc... MS949, on the other hand, only maps to Korean. Some codepages, such as UTF-8, UTF-16 and UTF-32, map to a standard generally known as Unicode. This is very useful because Unicode is the character set which includes almost all known characters in the world today. When processing both multi-byte and single-byte data, a Unicode codepage is recommended, which in the case of DI is equivalent to UTF-8 Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - This code snippet makes no sense... I at least was not too far off by suspecting that code. When I compile the code shown below using VC 6 I get " error C2059: syntax error : '&' " for the line " someClass *someFunction(&blah); ". When I compile using VC 2005, I get " warning C4189: 'someFunction' : local variable is initialized but not referenced". class someClass { }; someClass someFunction(someClass xx) { return xx; } int main(int argc, char* argv[]) { (void)argc, argv; someClass blah; someClass *someFunction(&blah); return 0; } Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

The dsw can be upgraded to a solution (and I am not sure, but I believe all its .dsps will be converted to corresponding .vcproj files).

    - Binary files question Hi, I need to convert a binary file to ascii format. I have a program which was written in Pascal many years ago and it creates config files which are in binary format(Or some sort of format that I dont understand - there are a lot of 'NULL's 'STX's and 'SOH's whenever I open it in Notepad++ etc.) I do not have the source code so I dont really know what kind of format the files are in. Does anyone know where I should start on this If I understood what the STX and SOH meant then at least I could maybe work out the format of the files. Thanks for any help anyone can give me on this.

    - WYSIWYG HTM editing within VS 2005? I'm looking for an easy convenient way to add HTML documentation to our projects. In the past, we have used FrontPage to create the following types of project related documents: Project Specifications User Documentation Developer Notes etc. Of course this had to be done outside of the IDE. I'm hoping this type of functionality is provided from within VS 2005 IDE. It would be nice to keep the project documentation accessible somehow from within the Solutions pane. I tried adding a "Web Site" project to the solution, but find that WYSIWYG editing functionality a bit cumbersome for the type of documentation I am concerned with. Is there any type of "SharePoint Designer" integration with VS 2005 Thanks Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - Limiters /Delimiters, Managed C++ The String::Split function is very usefull, but I've got an ever increasing number of delimiters to use with it, including characters from UTF-8, like those pesky curly quotation marks that Word puts on everything and look like foriegn lettters when opened in anything else. Is there a method that will specify what you don't want delimited instead i.e, if it isn't an ASCII upper or lower case letter or number then it is a delimiter.

    - Problem in Image Retrieving Thanks for your reply. Actually I have created the Dll with image creation inside of the dll function. When I invoke the Dll from java and displaying that image in screen. At that time image retrieving takes 50 more seconds to display. So that is my problem. I need to send that full byte array data to the Java function and write image file in java. In Dll, the callback function calls repeteadly still full image capture. Each time retrieve 1024bytes from SDK library. So I need to append the data in memory stream of each time. Then only I send the full image data to the java function. Can we write the data through the file only why not in memory stream Please give your kind of suggestion. Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - Periodic TimeSetEvent Interval not triggering properly The periodic TimeSetEvent call to a delay greater than 429496 does not trigger properly. Is there a fix for this problem The delay values that are being utilized are well within the min and max returned by the timeGetDevCaps function. The winmm.dll is dated 08/04/2004 and the winmm.lib is dated 02/18/2005. Code: delayTime = 600,000; timerID = timeSetEvent(delayTime, 1000, CallBackFunction, (DWORD)serial_ptr, (TIME_PERIODIC | TIME_KILL_SYNCHRONOUS)); The CallBackFunction should be called every 10 minutes instead it appears to be ocurring at approx 2.8 minutes.

    - Help! DLL errors when I exited my program Lejing wrote: Unhandled exception at 0x023b69f9 in CAMPARd.exe: 0xC0000005: Access violation reading location 0x023b69f9. That appears to be an error message. There appears to be a problem you need to fix. Unfortunately it might be difficult to find the error. Your program is probably doing something it is not supposed to do, such as use a pointer or index or subscript that has an incorrect value. The easiest way to diganose the problem often is to look at your program closely, but that takes time. Often however there is no other diagnostic method that is easier. It is difficult or impossible for anyone else to help, except to possibly suggest how to attempt to diagnose the problem. For now, the best thing to do is to attempt to look at your program to find problems. One thing to look for is anywhere that a return valud could be returned by a function that indicates an error but your program does not check for errors. If your program then uses a value that the bad function call should have provided then that could cause an error that is more serious such as your program has encountered. There are many other possibilities and as I said it is difficult for us to guess at the cause. Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - Create a Wrapper DLL to access C++ lib classes in C# I need to access classes from a C++ project in a C# project. After a bit of research, it looks like the solution is to create a wrapper around the C++ library, create a DLL, then use it in the new C# project. All the examples I have seen reference just small static functions. What can I do, or where can I go, to get a good example of what I'm trying to accomplish Thank you, Ryan Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - C++, COM+, SQL Server Hi, Our company is beginning to use some old technologies: COM+, C++ to connect SQL. I start my career from C#. So I would like to find some resources to learn these technologies. Can anyone provide any information, such as any hyperlinks or books I would like to know how to use C++ to call some stored procedure and update/insert/retrieve data on SQL server database. They look using small pointer to do that. If these sources have some examples, it is great. Thanks in advaced. Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - fatal error C1083: Cannot open include file: 'stream.h': No such file or directory I guess you are using command line to compile this source code. Make sure that you set Environment variable "lib" of command prompt window correctly. When you type the command "set lib", you should see something like this "lib=c:\program files\Microsoft visual studio 8\vc\lib;....." which is the path compiler tries to locate the libraries. You should be able to find libcmtd.lib in one of these paths. If you are using the Command prompt window provided by Visual studio, the environment should be set correctly for you. Otherwise, you have to set all the enviroment variable yourself. Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - Debugging moved source files Hi all We have a small problem regarding debugging code after it has been moved. Example: We have a code project at e:\source\project\4.1.2\src. When the project is built, the binaries will be placed in e:\source\project\4.1.2\bin\. During some test, the entire directory might be moved to another location, e.g. c:\project\4.1.2\. What we would like to be able to now, is to run the application, start debugging (attach the debugger to the running program) and be able to step through the code. Can anyone help us figure out how to explain that the sourcefiles have been moved all together, and no longer reside at e:\source\project\4.1.2\. That is the path that is written in the debug files. Either that, being able to tell once that all the files have moved, or even better... Can someone tell us how to build a debug version of our software, in which the path to the source files is relative based on some root path In the example that could be e:\source. I hope someone has been here before, and can help us with an answer. /Anders Tag: Visual C++ General Getting MS Access Updated/Inserted rows Visual C++

    - Multithreading and DoEvents. Saania wrote: Second, my main thread ( that creates the two threads) terminates before the two threads return. I have tried using AutoResetEvent (or ManualResetEvent) to wait for the trigger from the threads, but all the help I see on the net relates to creating a ThreadPool for the threads. And I dont know how to use the ThreadPool and pass the LPVOID parameter ( as you do with CreateThread function to pass the class object in the dll). The object state passed in a threadpool is used to trigger SET (OR RESET) function of the AutoResetEvent, so how can I pass my object to a ThreadPool AutoResetEvent and ManualResetEvent are part of the CLR or something such as that. I don't know if that is in or out of scope for this forum but I can't help with the CLR or whatever it is that includes AutoResetEvent and ManualResetEvent.

I am working on an alarm application that has to be more or less real time. In case of an event, a new record is inserted into an Access database in a table named "Events". I need a way to either "detect" this insertion of a new row, or getting this row automatically in a recordSet sent to my VC++ application. Please advice on how to implement this or anyother alternative...

Thank you

Sahir Shah

You can use the FileSystemWatcher class to monitor the mdb file and notify your application of any changes to the file. Once you receive notification of a change you can query the table to identify changes. You need to have an "AutoNumber" field in the table so you can know if a new row was added when you query the table.

Simple Samples

The answer depends on the database server/system. If it is SQL Server you will get better answers in the SQL Server forum. It has been a while since I researched something such as this but a SQL Server specialist might tell you to look at triggers. I am not sure if that would help, but I don't know what database you are using.
