I was using the connection string supplied in this site under the heading 'ado connection strings' and it works fine when using the CDatabase class. However the CDatabase class is very slow for what I want to do and I'd like to use the odbc api. I'm trying to make a connection like I did with the database object except using SQLConnect. I can't seem to get it to work, any suggestions would be very appreciated. Here's what I have so far:
"Driver={Microsoft dBASE Driver (*.dbf)};DriverID=533;Dbq=c:\dbasetables\;"
that's what the connection string looks like when it's finished.
I've used this same code in another project to connect to a datasource (sql server), but I can't get this to work. Thanks in advance!!;)
If it's broken, I probably did it

Verify that you have the driver name exactly right. I think it is dBase instead of dBASE. Also, shouldn't you be using double backslashes?

I changed the dBASE to dBase, and it still doesn't work. actual string is returned from CFileDialog as to where they wanna put the .dbf file at, so that's what it actually looks like after it's formatted already. I just put it in like that for clarity.

You're welcome, even though I did not provide you with any help. You seemed to have fixed it on your own accord.

I just now set up my odbc error handling and it's telling me that I specified an invalid string or buffer length. I had always used SQL_NTS before, and now I've tried 512 which is how big I specified the character arrays, and still no luck.

How about a small code snippet, that includes the call to SQLConnect()?

I don't know if this is only ofr Logitech, but I want to GET/SET the mouse direction settings, which can be calibrated using Windows's Mouse Config Panel (well, if you have WinXP, I guess you need Logitech's MouseWare).
Is that possible?

Hi all!
I'm trying to build a Visual C++ application (a dialog application in Release mode with a simple window that creates a new thread in CWindowDlg). It compiles but in link I get this error:
<br />
LINK : fatal error LNK1561: entry point must be defined<br />
NMAKE : fatal error U1077: 'link.exe' : return code '0x619'<br />
Does anybody know what it means and how I could eliminate it?
Thank you in advance!

IT sounds like you either don't have a CWinApp class defined (e.g., somewhere you need the line: CMyWinAppDerievdClass theApp;)
Or your your project settings are incorrect and you aren't set to run an MFC project or something.
Remember, even if you win the rat race, you're still a rat.

|
|
|
|
Well, I have in my code the line
CWindowApp theApp;
and I have "Use MFC in a shared DLL" so I don't know but I think they are not the problem...
Usually, I can compile and link with no problem, but when I try to create threads then I got this problems in link.
Any idea?
Thanks!

Are you using the /ENTRY option with the linker?

Where should I write down this option, please?
Thank you.

|
|

In the .mak file. I assume you have one since nmake was mentioned.

cliente and servidor are console applications. First I made these console applications because I needed to work with CORBA and I thought that it was the easiest way, but they didn't work quite well so I tried to build the same application with MFC (creating a new thread in the main window that actues as the servidor (server)) but I get that link error.
Here in the make file, servidorV is the equivalent MFC application as servidor (at least I think so).
Thank you for your help.

It looks like only 1 of the three "link" lines have the /ENTRY option.

ok, I understand...
My problem now is that I don't know which is the main procedure in the application... I'm working in Visual C++ and my app is called Window (I only wrote /ENTRY:WinMain so I could know if I had understood you).
Thank you.

Try changing the .mak file to the following in hopes of narrowing down which of the three modules is causing the problem:
todo: cliente.exe<br />
<br />
cliente.exe: cliente.obj imevoc.obj<br />
link.exe cliente.obj imevoc.obj TAO_Portableserver.lib TAO_RTEvent.lib TAO_CosNaming.lib TAO.lib ace.lib /libpath:"C:\corba\ACE_wrappers\LIB"<br />
<br />
cliente.obj: cliente.cpp imevoc.h <br />
CL cliente.CPP /MD /W3 /GX /O2 /I "C:\corba\ACE_wrappers" /I "C:\corba\ACE_wrappers\TAO" /I "C:\corba\ACE_wrappers\TAO\orbsvcs" /D "WIN32" /D "NDEBUG" /D "_WINDOWS" /D "_MBCS" /FD /c<br />
<br />
imevoc.obj: imevoc.cpp imevoc.h<br />
CL imevoC.CPP /MD /W3 /GX /O2 /I "C:\corba\ACE_wrappers" /I "C:\corba\ACE_wrappers\TAO" /I "C:\corba\ACE_wrappers\TAO\orbsvcs" /D "WIN32" /D "NDEBUG" /D "_WINDOWS" /D "_MBCS" /FD /c
If this works, do the same for servidor.exe, and then servidorv.exe.

And the nmake throws:<br />

Stop.<br />
when it ends compiling.
servidor and cliente are OK.
Which could be the problem?
Thanks!

Do any of the following modules contain a WinMain(), or equivalent, function:
ventana.cpp
ventanaDlg.cpp
imevoc.cpp
imevos.cpp
imevo_i.cpp
imevo.cpp

I think so since I've created the ventana.dsw project and in other projects I had no problems, but I don't really know which is the function that begins here
When I build my project in Visual C++ instead of DOS console with nmake, I get this different message error:
<br />
ventanaDlg.obj : error LNK2001: unresolved external symbol "protected: virtual void __thiscall CVentanaDlg::OnOK(void)" (?OnOK@CVentanaDlg@@MAEXXZ)<br />
Release/ventana.exe : fatal error LNK1120: 1 unresolved externals<br />
The error that I get in the DOS console is about the entry point as I told you... I can't see the relationship between these errors.
Waiting for your help and knowledge 
Thanks!

Why don't you open the ventana.dsw workspace, click on Project/Export Makefile. Compare this .mak file with the one you are currently using. Notice that it probably contains a lot more .cpp files.

Hello,
I need to control a webcam and analyze picture by picture (and pixel by pixel) but I do not really know where to to start. Do you have to have the manufacturers API or is there any windows standard interface that you may use? Can you use VC++ or VB classes? Do you poll frame by frame or do you get a continuous stream? What format would you expect to get on the pics/stream, complete pics or changes? etc etc.
Thanks for any help I may get.

There are lots of options that are set in project settings, things like INCLUDE paths, DEFINE-d symbols, and the like.
You say it doesn't do it, but you aren't giving any clues as to what errors you see.

now i am one step forward and only problem is the following
cl RegistryTools.cpp MyApplication.cpp -FeMyApplication2.exe
