unless you're converting that long to text when you output, then yes, the file has to be binary. otherwise, you will end up with a bunch of unprintable characters.

I have a question about debugging in VC6.
When the IDE breaks at a location and you look at the variables window for the "Value" of a class if the class is descendent of a CObject you'll see the class name ex: {CMyObject} but for a CString, CRect, CPoint, etc. you'll see the value(s) of the most important member(s) of the class, CString - the actual string, CPoint - the X and Y coordinate.
So my question is: Is there a way to control the text in the value column or the variable window of the IDE for a class or is it the IDE that decides what to display? 
For example if I created a CMyString class that's a descendent of a CObject class. When I debug in the "Value" column I only see {CMyString}, I always have to click on the "+" sign to see the value of the CMyString class. I would be very useful to have control on what the IDE would display for a value of a class.
But if the IDE decides what members is displayed for certain class, then I guess I would kind of be impossible to do...
Thanks...

You have to edit this file:
(wherever you installed Visual)\Common\MsDev98\Bin\Autoexp.dat
Add a line like this:
CMyString=<membervariable>
Fortunately, there are (should be) some instructions within this file that explain exactly what you can do. I'd recommend closing down Visual before editing this file.
No generalization is 100% true.
Not even this one.

I'm writing this code to control a mechincal syring and I keep getting this error when I try to build it.
header file: int pl32ComClose(void);
call fn in .cpp: pl32ComClose();
error recieved: myc32.obj : error LNK2019: unresolved external symbol "int __cdecl pl32ComClose(void)" (pl32ComClose@@YAHXZ) referenced in function _main
How do I go about fixing this? I'm using a predefined .lib and .dll file for the functions. Am I not linking correctly to the files? Am I calling it incorrectly?? Any help would be greatly appreciated.

Try including the header in your .cpp like this:
extern "C"{
#include "lpr32.h"
}

That is still not working. I include the header #include "Test32C.h" originally. I tried it this new way and the same error came up. Thanks for trying though. any other suggestions???

It's hard to say without further info:- Does it work if you link the DLL in a C-only project?
- Could it be the DLL was built for a different version of VC++ than you're using?

Hello all,
I've been lurking here for quite a while and have run into a problem that I can't seem to find an answer to, so I thought I'd give you guys (and gals) a shot.
I'm trying to create a MAPI preprocessor using a minimal Transport Provider as described in the MAPI SDK. This Preprocessor is to be used in conjunction with Microsoft Exchange. According to the SDK, the Preprocessor method is *supposed* to be called from the MAPI spooler. In my case, it is not being called at all. There are a statements buried within the SDK documentation about the case of a tightly coupled Transport Provider and Message Store bypassing the MAPI spooler entirely.
"This implies that the individual parts within the combined service provider should interact with each other in a way that simulates the interaction they would normally have with the parts of the MAPI subsystem that are not being used." - directly from the Microsoft SDK.
What I suspect is that the Exchange provider is a tightly coupled Message Store and Transport, thus bypassing the spooler and not internally duplicating the spooler's behavior by calling other registered preprocessors.
Can anyone out there confirm, deny or perhaps point me somewhere to find out if this is in fact the case?
To answer the first wave of "Have you tried..." questions, here goes:
No, I can't use Hook providers as they only get called after a message is sent, I need to modify a message before it is sent.
No, I can't use Outlook Automation, it only works within the outlook client app, I need to grap ALL messages, not just those sent from within Outlook (besides, the Outlook automation is grossly incomplete and buggy).
Yes, my Transport Provider is being loaded, and logged into properly when a MAPI client (including Outlook) is used.
Thanks in advance for any light or dark that you might be able to shed on this...
PS. You guys (and gals) are pretty funny to sit back and watch.

I have a little problem with WinForms.
I've created a Managed C++ app. Then I wanted to add a WinForm but I couldn't find the appropriate function. So I decided to see the samples.
I find the solution but I still cannot use the designer as in C# or VB.Net.
Does anybody know how to add a WinForm to VC++.Net which can be modified in the designer.
Thanks in advance

When calling GetOpenFileName w/ multi-select enabled, is there a way to determine the buffer space required by the lpstrFile pointer ?
|
|
|
|
|
I don't think so.
GetOpenFileName() returns FALSE if you specify a buffer that's too small. I ran into this annoying problem some time ago, and now always allocate a generous (64K) buffer when I call the multiselect version of GetOpenFileName().

Are you linking with one of the multi-threaded CRT libraries?
LIBCMT.LIB or MSVCRT.LIB

I'm not sure at all, but I would have checked the Project Settings. Project menu -> Settings... -> C/C++ tab -> Category: 'Code Generation' -> Use run-time library: 'Multithreaded' (or 'Debug multithreaded' for debug mode)

Does anybody know how to give a service parameters at startup???
|
|
|
|
|
When you popup the property page for a given service, there is an edit box at the bottom that allows you to specify start parameters. This can only be done if the service is stopped.
