I compile my projects using this platform. When i give exe-files, compiled by it, to my friend application doesn't find all dll it needs, because friens don't have this platform. But when i had seen what dll it wants, i realized that it wants dll related to netframework, which i don't use in my applications. And i don't know how to exclude it from using.

Are you sure you're not using any managed extensions? Try using SPY++ to see which modules your app calls.

I ran across a document a while back about this issue. (This is why I have not used my .NET that I paid over $1K for!). The article stated that any program that you compile with Visual Studio .NET requires the .NET Framework to be installed on the client machine running that program.
The article stated that future versions of Windows will be shipped with the framework, but as of now you have to download and install it from the Microsoft web site. (This is primarily why I've not developed anything with it, because I was nervous that the people running my program would have to spend hours downloading the framework in order for a simple utility to run).
I may be entirely wrong, someone please correct me if I am (I'll be installing 5 minutes after your message!). But I did read a document that stated that.

That is incorrect. You can still write C/C++ apps that are completely native.

...Installing VS .NET right now!!!! I've had the program for almost a year now without using because of this fear!!!
Thanks for your post!

Heh, it is a VERY common mistake. Microsoft hyped .NET so much that many people think that VS.NET only produces .NET programs.

If you sure that you can write application without loading unnecessary DLLs.
Could you help me how to prevent their loading.I use Win API.

What is the name of the DLLs? The usual problem is that someone tries to ship the debug build which links to debug DLLs.

Hello
Below is my code about List Iterator. It is ok when
i compile it. But when i try to build it. the following
errors come up.
"DoubleOrderedLinkedList.obj : error LNK2019: unresolved external symbol "public: int __thiscall ListIterator::getNext(void)" (?getNext@?$ListIterator@H@@QAEHXZ) referenced in function _main"
Could any body here help me solve this problem?
Thanks,
Andre

that message is given when in the header file you wrote a function that in the cpp file is not used
Written by: Rafael Fernández López.
void life ( bool me, bool her )
{
if ( her )
{
me = true ;
}
else
{
me = false ;
}
}
|
|

|

You must have the implementation of your template class in the header file. Just copy all the functions from the .cpp file into the header file and it'll work.
And while you are at it, pick up a book on C++ and read very carefully in the chapter which handles templates.

Is anyone aware if it is possible to pass a db handle between two seperate applications? And if so how is this accomplished... do you utilize the command line of the CreateProcess command. And if so, how would you pass it (not sure how you would convert it to a string etc). What i am trying to accomplish is not to have to open the same DB on new instances of programs designed to perform certain task. This is an ODBC connection as well. Any insight is appreciated

By applications (and the mention of CreateProcess()), do you mean EXEs? If so, information sent to the spawned application is on the command-line. I'm not sure a handle would be valid across a process boundary.

Behavior varies from one database to another, from driver, etc etc etc.
With Oracle sqlnet api handle may be can passed btw processes, also not supported.
SqlLib handle, sqllib api can be passed safely cross boundary and I think is supported.
ODBC drivers do NOT support such behavior, it may or may not work with next update of oracle or vendor driver.
Proper solution would be to build out of process STA com object, that performs access to database.

Handles are most often bound to the process in which it was acquired. ODBC handles fall into that category!
The post above this one mentions building an out-proc COM server for doing the actual database acces. This may or may not suit your needs. Is it necessary to share the actual connection between the processes? If not, then you can just pass the source DSN to the other processes. Otherwise, the COM server is your best shot.

How about trimming the code snippet down to just the relevant pieces? What line of what file is firing the assertion?
One thing that looks suspicious is that COperationRecordset's constructor needs to assign the value 2 to m_nFields.

The error message is
Debug assertion failed !
Progam : c:\FinalYearProject\work\debug\main.exe
File : dbcore.cpp
Line : 3282
For information on how your program cause an assertion failure, see the VC++ document on asserts.

Anson Tong

The statement at line 3282 is:
ASSERT(m_nFields != 0);
My suspicion was right!

I'm writing a dll and I want a .lib file to be produced. Problem is the file isn't being created. I have unchecked the "Doesn't produce .LIB" option under the Link tab in the project settings like I'm supposed to, but for some reason it still isn't producing the .lib and I don't remember how to fix this.
So what do I need to do? I'm using VC++ 6.0
Thanks!

That checkbox never worked for me....
I would modify .dsp to:
LIB32=link.exe -lib
# ADD BASE LIB32 /nologo
# ADD LIB32 /nologo
TargetPath=.\Release\My.lib
from
LINK32=link.exe
# ADD BASE LINK32 /nologo /subsystem:windows /dll /machine:I386
# ADD LINK32 /nologo /subsystem:windows /dll /machine:I386

When I use the MAPISendMail command with the MAPI_DIALOG flag it brings up the dialog in Outlook (loading mapi32.dll library) and Outlook Express (loading msoe.dll library). If the mail client is closed, the message will send in Outlook Express, but will sit in the outbox of Outlook until the program is opened and the send/receive button is pressed.
How can I change this behavior?
I can't create a new process of outlook.exe because I do not know if the mail has been sent before killing the process...
Help please, last time I submitted this question I only got one response (which unfortunately did not work out). Thank you in advance...

Can you provide a code snippet of how you are using the mail API?
