Hi everyone,
I'm developing a c++ multithread app create a thread in a separated class:
I've also used _beginthread in the main function of the program without any problems, here my code looks liks this:
_beginthread(StartTCPService,0, NULL );
In my second class (tmpClient) I tried to do the same with this code:
<br />
void ClientThread (void *socket)<br />
{<br />
SOCKET sd = (SOCKET) socket;<br />
}<br />
and to create a thread:
_beginthread(SocketClientThread,0, NULL);
But my compiler complains that:
error C2664: '_beginthread' : cannot convert parameter 1 from 'void (void *)' to 'void (__cdecl *)(void)'
I tried to convert the thread func to a static one, but with any luck.
What's wrong with this code, why can't I create a thread ?
Regards,
Niels Bergsma
Note: I'm developing with VisualStudio .Net 2003

0x00010000, // 64K
0x00020000, // 128K
0x00040000, // 256K
0x00080000, // 512K
0x00100000, // 1024K
0x00200000, // 2048K
0x00400000, // 4096K

Hai, I want to use the Dialog Interface for my database applications.
According to the Teach Your Self C++ Book Chapter 15 "The Subject on Database Applications Using ADO. I need to manage the Classes on my Own if I choose Dialog instead of MDI or SDI.
I'am unable to add these classes especially the View Classes. It says I must add a resource file manually.
Just how do I do this.
I would appreciate if you started from the beggining to the end.
regards.
Lk.

The easist way is to start your application with an MDI or SDI. Since your code is dialog-based, you should not have many porting problem.

Hi,
I am able to wrapp all the class method in unmanaged c++ into managed c++ but i
could't able to wrapp Friend function. Please let me know if you have any idea.
Here is an example
Class UnManaged{
int i;
public:
UnManaged(int k){ i =k;}
friend int getInt(){return i};
friend bool operator < (Unmanaged *U1, Unmanaged *U2)
{return (U1->i <u2->i);}
}
How can wrapp These two function in my wrapper class called Mangaed.
public __gc class Managed {
Unmanaged __nogc *unmanagedObject
public:
Managed(){unManagedObject = new Unmanaged(10);
}
Thanks in Advance.

I have a database program. I am using accses databese with Microsoft.JET.4 Engine. Can i create a database with jet. If no, then i want to my own program create own database inplented in my project. How can i do this in "Less painful" way.

hi Saksida Bojan!
The most unpainful way is to create XML files because .NET provides very comprehensive namespace for xml called System::Xml just use this and it will be even easier if you use serialization to deal with your XML files which can be found in System::Xml::Serialization. I have done it in VB and it worked fine for me, provided if you are not going to use very huge data processing.
Hope it helps.

I don't use xml file, but Access database throu Microsoft.Jet.4

You can easily create a Jet database using ADOX.
Here's an example in C#.

After you create the catalog you can add tables, then columns. I use this technique in one of my products.
Hope this helps.

Hi,
do any of you know how to open microsoft word in C++? i need to pass strings out to a template word document to fill in.
(john.parr@logicacmg.com)
I know the VB script method:
'Used to open word and populate CD label values in a word template'
Dim oWordApp
Dim oWordDoc
Set oWordApp = CreateObject("Word.Application")
If oWordApp Is Nothing Then
MsgBox "Couldn't start Word."
Else
oWordApp.visible =true
Set oDoc = oWordApp.Documents.Add("C:\cdtemplate.dot")
with oDoc
.bookmarks("mainTitle1").Range.text="HELLO"
.bookmarks("subTitle1").Range.text="TEST_DATA, PLAN_TEST - 393"
End If

This is the Visual C++ .NET forum.
The .NET way Interops the Word COM Dll, by converting it into a .NET assembly with TlbImp.exe and creating Runtime Callable Wrappers; (this makes it REALLY easy to manipulate the Word application object).
You probably want to ask this question at either the COM or Visual C++ forum.

Much thanks, I will ask in the said forum.
Thanks again

I need to develop a system to monitor operations performed on files/folders.
Such as
1. open,
2. read,
3. write,
4. close,
5. copy,
6 rename,and
7. move
I have stumbled upon one solution.
Having a "File System Filter Driver" which monitors every atomic operation performed on the file system. But the information available out of the driver is too huge to classify into a single user operation.
For example
(*) IRP_MJ_WRITE is the Major function getting initiated when a user tries to write a file.
(*) However more than one IRP_MJ_WRITE happens for a single write.
(*) when user saves the document twice,it is difficult for me to group the IRP_MJ_WRITE's into TWO user writes.
Someone help me on how to proceed on this, or may be any other solution to this problem.

Google has plenty of hits, but it seems odd to me that you'd ask for something so complex, but want a complete source listing, rather than some references on how it works ?

Hello Everyone:
This is my problem:
I have C# project compiled as a DLL. The C# class is defined as:
public Cs_Class
{
String name;
public Cs_Class(String n)
{ name = n; }
....
}
I have another MC++ project that uses the DLL. The MC++ class is defined as:
public Cpp_Class
{
....
void Test(String* testStr)
{
//Create the c# class
//
Cs_Class* c = new Cs_Class(testStr);
}
}
The compilation/linking was fine. I then encountered a run-time exception:
System.MissingMethodException: Method not found: Cs_Class..ctor(System.String)...
Strangly enough, if I took out the String parameter in Cs_Class constructor and not pass in String* in MC++ class when constructing the Cs_Class object, then everything was fine.
Why??
Thanks in advance.

Does anyone know where I can find pen-and-ink filter source code to transform images to pen-and-ink style?
Cheers

No, and I've looked around for sources on image filters a lot. However, I'd imagine that some sort of edge detection would be a good starting point.

Hi all,
I've got to add multi-language functionality to an application and don't really know where to start.
I need to be able to add new language files with the least amount of change. The language files are to be stored in a directory which the application will read. The language files are to be stored in DLLs. I'm wondering if anyone knows if it's possible to be able to add a file to the directory without having the project rebuilt. i.e. the app will pick up any new language files and add them/include them in the language options.
I was looking into using resource files and culture info for this project. Would this be a good way to go and could I get my required functionality by using this method?
All help gratefully recieved by a desperado. ![Smile | :)](https://codeproject.freetls.fastly.net/script/Forums/Images/smiley_smile.gif)
