Sorry, no idea. As I said above, I have done this myself without problems in the past. I can only assume that you tried opening one of the VC6 solutions in a later Visual Studio which converted or somehow corrupted one of the project files.
Use the best guess

The problem is obviously that you converted the old workspace into a new one (.dsw to .sln). After that you can't use it anymore with VS 6. Your best option is to revert to the files you had before conversion. If you don't have a backup you can either try to open the .dsw file (that contains the old workspace information for VS 6) or you may try to recreate all the projects, add the source files and hope that you get the project settings correctly.
I have installed VS 6 and some newer ones (up to VS 2010) in parallel on my machine. Usually this gives no problem. The key rule is: Always keep the projects separate, never open a project in anover VS version than it is intended for.

If the problem was so obvious I would not post it here.
Please read my OP and follow-up response.

In the C++ world, VS6 used different project and workspace files from subsequent VS versions. Here is a summary:
Project Workspace/Solution
File File
VS6 x.dsp x.dsw
VS.Net 2002 x.vcproj(?) x.sln
VS.Net 2003 x.vcproj x.sln
VS 2005 x.vcproj x.sln
VS2008 x.vcxproj(?) x.sln
VS2010 x.vcxproj x.sln
This is from memory - there may be errors.
VS6 also used x.sln files but they were for web projects (and maybe something else?). If you end up with a x.dsp and x.sln file with VS6 then something is confused. I am doubtful that it will work. You probably want to delete the x.sln file, go to VS6 and select "Start a new project" and add your existing x.dsp to it. This should create an x.dsw file for you. If it creates or tries to use the x.sln file then something is wrong...

Thanks,
unfortunately I just deleted the sln and it did not help.
I have no VS greater that 6 on my box, so everything works in VS 6.I may try adding VS 2008 again to test the CMAke.
Many thanks for your input, appreciate it.
This also partialy explains why I can start a new project from dsw file but I cannot add DSW into existing project - IDE complains.

Hi
I need help with the following knowledge base article
http://support.microsoft.com/kb/147578[^]
In a method of my main window I have the following code
CMainframe::Process()
{
HWND main_handle = (HWND) this;
In my worker thread
CWnd* windowptr = new CWnd;
windowptr->attach(main_handle);
windowptr->SendMessage(...
My question is this coding correct as the article says
When working between threads not to pass object pointers
Rather handles and attach the handles to the MFC object
Thanks

What exception is being thrown? Are you trying to send a UI-related message to the main thread from a worker thread?

The worker thread is communicating with Hercules
dos C program when I get information
From Hercules I do a readfile (named pipes)
And send the buffer ptr as a wparam
The buffer is allocated on the heap via new
So any thread can access it

Hello everyone.
I was wondering what advice can you give on how to create a data/business model in C++. I mean, when working with C# I usually have no problems, simply follow .NET's guidelines, but it seems there aren't guidelines in C++ on this regard. Is there any example you'd like to share?
I'm thinking common scenarios like a sales system (product, warehouse, pricing, purchase order) or a search inverted index (term, documents, posting, posting lists, dictionaries).
What are your thoughts?

Hi,
I have a dialog box and an Edit box control on that. I want to make this edit box accept only digits ( 0 - 9 ), no character or special characters.
I have changed its property "Number" to true in resource dialog but when I run the application, the screen blinks every time I press any character.
Or is there any way that I can manually change it to accept only digits.?
Any help will be appreciated.
Regards,
Mbatra

You could overwrite the OnChange Handler (I think it was EN_CHANGED or something like that) and manually get the text, check for any non-digit and remove it. Then set the corrected Text with SetWindowText(), or ReplaceSel().
There are however several pitfalls you need to avoid. First, setting the text programmatically also calls the event handler, and you need some status variable to prevent "recursive" calls.
Second, You need to take the cursor position into account. When you call SetWindowText(), usually the whole edit control content is selected. You could set the cursor position to the end with SetSel() (IIRC you need two calls, one to mark everything and at the same time set the cursor to the end, a second one to mark nothing and leave the cursor where it is.) Since the user may have entered something in the middle you may want to get the cursor position before changing anything (with GetSel()) and set it back to that position later.
I usually avoided these issues by letting the user enter the wrong values and checking them when the control lost focus, unless where was a strong argument against this approach.

How about sharing your solution here?

Hi,
Here is the solution:
I handled OnUpdate() function.
This will not allow user to enter characters or special characters.
void Position::OnUpdateEditRotate()
{
CString str;
(static_cast<cedit*>(GetDlgItem(IDC_EDIT_ROTATE)))->GetWindowTextW(str);
LPTSTR pBuff = str.GetBuffer( 10 );
bool bProblem = false;
for ( int indx = 0; indx < str.GetLength(); indx++ )
{
char nChar = pBuff[indx];
if ( ( ( nChar >= 'A' ) && ( nChar <= 'Z' ) ) ||
( ( nChar >= 'a' ) && ( nChar <= 'z' ) ) ||
( ( nChar >= 33 ) && ( nChar <= 47 ) ) ||
( ( nChar >= 58 ) && ( nChar <= 64 ) )||
( ( nChar >= 91 ) && ( nChar <= 96 ) )||
( ( nChar >= 123 ) && ( nChar <= 126 ) ))
{
MessageBox();
}
else
{
bProblem = true;
break;
}
}
str.ReleaseBuffer();
}

Thanks for sharing. It would probably work same if you check just for < numbers > range.

Yes Indeed, but in that case it will block some keys also (e:g: Del, space, etc ...).
I want to block only characters and special characters.

If using DoDataExchange and DDX_Text, then you also have access to DDV_MinMaxInt (And other DDV friends[^])

I am certainly not an expert but I am quite sure that the code that you posted is not C, C++ or MFC. At least it is no variant of C, C++ or MFC that I recognize. You sure you are in the right forum?
|
|
|
|
|
I'm not sure where should I post this but it's part of the code in Clips (C Language Integrated Production System ) environment which is software tool for building expert systems.
please let me know where should I post it?
|
|
|
|
|
I already gave you a link to the Clips page. You need to try there, as that is where you will find other people who understand that system.
Use the best guess

thanks,I have used that link but I think may be I could find my answer here.
thanks i'll try once more

If it were me looking to know about someone else's language or IDE, I would go to the source and ask them. For CLIPS, I would go here[^]

You've been told that this forum isn't suitable, yet have decided to post here again. No matter how may times you post CLIPS != c || c++, the c=part denotes it can be integrated with c-based systems. Additionally CLIPS is relatively specialised, rule based programming is different to the way c operates.
All this adds up to one thing: the advice I have seen here so far is spot-on: don't post this here as this isn't the correct forum and few people here will have an interest in CLIPS, your chances will be vastly improved by posting on a specialised CLIPS forum where everyone is there as they know about/are interested in it.
The defrule for Rule0 has an unbalanced number of brackets BTW my guess is there is one missing at the end of the "not" line, and the ? after tank-is-full looks suspicious. Of course I know next to nothing about CLIPS, which is why going to a CLIPS forum would be so handy.

yeah, I do that but I didn't get any answer so I post here.
yours help a lot because every time I check every thing else rather than brackets. I didn't pay attention to that at all, it was just frustrating to check sth again and again and don't know what to do.
my problems solved, THX
