That is excellent, thanks so much for your help in this matter, you make it seem so easy after I've been trying so hard for so long.

I will certainly give this a try, I'm sure it will work fine for me.

Thanks again,

Craig

One way would be to trick it. Set the hyperlink in question to some value that has meaning to you. THen override the OnBeforeNavigate method of the web browser control. Parse the URL and redirect it to open a dlg.

a href="opendlg" (would be nice to have

 tag support)

OnBeforeNavigate(LPCTSTR lpszURL, ...)
{
    if( !strcmp(lpszURL, "opendlg" )
        dgl.DoModal()
}

I've used this type of trick before. It might not be the best but it gets you there without having to implement IDocHostHandler and such. You could also do this with script on the page itself.

Is there a "easy" or "best" way to insert a value into the registry using a MFC Dialog type application.. What I would like to do is..

Have a dialog type app, with a button that allows me to add a value\key to the registry this value would be pre-defined in the source code.. then whith a second button read\verify the registry key exists..

any ideas?

Look at RegCreateKey and the other related function.

Debug v. Release

Hmm, I'm not sure if this is a common problem. I have a .dll that when compiled under Debug mode in VC++ 6.0, runs perfectly. But when I compile a Release version, the .dll can't correctly access the registry, redraw the window (I'm using InvalidateRect()), and will even throw an error when on exit.

So, I'm quite confused as to why this is happening. I don't really understand the difference between Debug and Release, I guess. Does anyone know what sort of compile options could be causing the problems I'm having?

thanks!

I have the same problem, and I don't know what to do about it. Accessing the registry, that is. Are you using the OpenRegKeyEx or the function(I forgot its name)?

I'm using CRegKey...

After reading the article recommended in the second reply, I'm betting my problems is my frequent use of the

assert(someFunction() == someVal);

programming no-no. Hope that helps!

ASSERT is ignored in Release versions so it doesn't matter if they're there or not.

CDynamicAccessor

Good day,

Has anyone used CDynamicAccessor with OLEDB? If so, I need help inserting data into the recordset using SetData(...). I want to set the value for one column on the specific row. I am using CTable with CDynamicAccessor. I have all the properties needed (IRowsetUpdate/Change, etc.) but everytime I call SetData I get DB_E_ERRORSOCCURRED. Any examples, help is greatly appreciated. Thanks.

I tried deriving a class and adding that support but still no go. I am using an ODBC driver because for some reason the Jet drivers don't support the options I need.

Maybe ODBC over Jet doesn't support these options either. Anyway, you need to reduce your problem to some simple case: can you SetData on simple table with 1 integer column? Are you sure you're calling SetStatus for each field in accessor?

It might not be the same problem but I ran into this error yesterday. It turned out I had an identity column in the column map. It would return this error when calling setdata.

(How do I) Set EOF to ofstream obj

6-Aug-01 6:18

I wish to use ofstream::seekp() to point and set
there the new EOF, but...

I tried:
{
ofstream o("blah.txt", ios::in | ios::out);

o.seekp(-30L, ios::end);
//set the ptr 30 bytes back from EOF.
//I want to set (the new) EOF HERE!
}
10x.

I think you're better off telling us what you're trying to accomplish. I'm sure there's another way to solve the problem. Trying to set the EOF yourself is a losing proposition.

Re: (How do I) Set EOF to ofstream obj

6-Aug-01 10:53

In another words, I wish to shorten the file, in 'n' bytes.
I wish to delete a stream of a known size and position,
from the end of the file.
Thanks again!

Two Q's : Executable name & Centering ?

6-Aug-01 4:53

I'm coding in Borland C++ Builder 5...

I want to change what the executable name is when my project compiles.

Also I want to be able to have my program centered on screen when it's
compiled, so when people use it with different resolutions and what not, it's still starts in the center of the screen.

Any help would be much appreciated.

Thanks,

Aaron
