Depends on the context. If you want the console not to appear for a program you're launching from another with CreateProcess, then some of the parameters in the call allow for this.
If you're talking about a program of your own, I guess the simplest way is to change it to a Windows program --it is admissible although you don't do any GUI stuff, and no console will appear.

But is there any method by which inside the console based application only can we make the black window disappear.
Wating for reply....

Do you own the source code of the app for which you want the console not to appear?

CDialog is the usual way.

Read up on CPropertySheet. A wizard is a property sheet with some style bits set to make it a wizard.

help needed::win32 error 10106

hi everyone
I recently visited the site codeproject & went through the tutorial
on install shield. I have recently made an installation which installs
my application in VC++ & at the same time installs the InterBase Server
& console. To achieve this installation i make entries in registry & for
auto starting the interbase server i have made entry in
HKEY_LOCAL_MACHINE\Software\Microsoft\CurrentVersion\Run
as InterBaseGuardian REG_STR <root dir="">IBServer.exe -a.
The installation is done in install shield for Microsoft VC++6.
I m facing a whimiscal problem whenever i install my appliaction in a compaq
machine that already contains Interbase server as well as VC++6 installed
in it. I tested my installation in an assembled machine which already has
both the things installed, but there it doesn't show that error.
As soon as the appliation is run it first shows message box "cann't create
socket" and then it shows "XTG unable to establish connection to the host
unknown win 32 error 10106".
Is this error due to the istallation script or its related with the
application or interbase server.
Please help me out i ll be really grateful.
thanking you!
regards
a struggling software engineer

As the error text informs you, this is an error from the XTG component (the ODBC driver?). If you indeed were a "software engineer" you'd know that an error 10106 is a Winsock error (WSAEPROVIDERFAILEDINIT). Perhaps the ODBC DSN is wrong?

char* template parameter [edited]

Paul M Watt31-May-02 21:55

Does any one know how if it is possible, and how to derive from a templatized class that specializes with a specific text string. Here is an example:

template<char* str>
class X
{
void print()
{
cout << "Your initialized Template string is: " << str << endl;
}
};

class Y : public X<"display">
{
...
};

//then instantiate and use the class like so:
Y yDisplay<"display">;
yDisplay.print();

// and here is the output
Your initialized Template string is: display

I can perform this feat with a DWORD. And I can instantiate an X type object that specializes on a text string.

//This seems to work fine.
X xObject<"hello">;

But I cannot figure out if it is possible to derive from a class that has specialized on a particular text string as a template parameter.

Thanks in advance.

Thank you for the link, it has a lot of good information. However my problem is a little more difficult than that. I actually stumbled on the solution to get the string literal to work, however I still have the problem of deriving a class from a templatized class that contains a specific string literal.

Example:

Does any one know how if it is possible, and how to derive from a templatized class that specializes with a specific text string. Here is an example:

template<char* str>
class X
{
};

//Notice how this class is derived from a specialized version of X with a specific string literal.
char DISPLAY_STR[] = "display";
class Y : public X<DISPLAY_STR>
{
...
};

THis is the error that I receive as well.
'X' : template argument 'str' : invalid address of local variable 'str'

Thanks again

This is no string literal. "foo" is a string literal. You're trying to use a variable and that will (of course) fail miserably.

If your intention is to "hide" the real string used as a literal behind another name, your only option is to use a macro:
#define DISPLAY_STR "display"

Well, you have a point with my misuse of vocabulary on the problem.

However if I want to instnatiate class X with a string parameter, the method that you have suggested will not work. If you read the link that Mike Dunn posted above, you need to create a variable with external linkage in order for the template to be able to use it. Here is a summary.

#define FOO_DEFINE "foo"

X xObject1<"foo">; //will not work
X xObject2<foo_define> //will not work either, same as xObject<"foo">

char FOO_STR[] = "foo";
X xObject3<foo_str>; //THe correct way to do it.

Anyway my real problem is that I want to derive a class Y from a specialized version of X, like so:

class Y : public X<foo_str>
{

};

class Y is not a parameterized class, however it will use a special version of X.

Thanks again.

The error message is descriptive enough. What is the linkage of DISPLAY_STR? It has to be external for the template to work. The problem has nothing to do with deriving from X<DISPLAY_STR>: you should meet it also by simply instantiating a X<DISPLAY_STR>.

I typed up a simple version like the example that I showed you guys and got it to work, then I found tha tI had declared <const char*> instead of <char*> as the template parameter and now it works.

Thanks

I now know that it is possible and here is how it can be done:

#include "stdafx.h"
#include <iostream>
using std::cout;

char szHello[] = "Hello ";
char szWorld[] = "World!";

template<char* str>
class X
{
public:
	void print() 
	{
		cout << str;
	}
};

class Y : public X<szWorld>
{
public:
	int i;

	Y();
};


Y::Y () : X<szWorld>()
{
	
};


int main(int argc, char* argv[])
{
	X<szHello> xObject;
	xObject.print();

	Y yObject;
	yObject.print();


	return 0;
}

Thanks for all of your help.

export template class in DLL

31-May-02 18:02

Can anyone tell me how can I export template class from a DLL.

I have created a wrapper to wrap some STL containers (as STL can't export through DLL boundary), and wanna export the wrapper as accessor.

Say, I declared in "ListType.h"

<br />
#ifdef DLL_EXP<br />
  #define MY_EXP __declspec(dllexport)<br />
#else<br />
  #define MY_EXP __declspec(dllimport)<br />
#define<br />
<br />
template class MY_EXP CMapList<T><br />
{<br />
   void insert(long key, T* pd)<br />
   {<br />
     ....<br />
   }<br />
   bool next() { .... }<br />
   T* get() { .... }<br />
<br />
   ....<br />
};<br />
<br />
class CMyClass1;<br />
class CMyClass2;<br />
<br />
CMapList<CMyClass1>;<br />
CMapList<CMyClass2>;<br />

I tried to use the wrapper class in the App project, but I experienced Access Violation with subsequence next() and get() calls.

How can I make sure the DLL project is exporting the class CMapList<cmyclass1> and CMapList<cmyclass2> ?

How can I avoid that the App project will use the declaration in the DLL, not generated CMapList<cmyclass1>, CMapList<cmyclass2> from the header file directly ?

Thanks for help ^^

Re: export template class in DLL

31-May-02 18:10

Sorry, the code section before should be :

<br />
#ifdef DLL_EXP<br />
#define MY_EXP __declspec(dllexport)<br />
#else<br />
#define MY_EXP __declspec(dllimport)<br />
#define<br />
<br />
template class MY_EXP CMapList<T><br />
{<br />
void insert(long key, T* pd)<br />
{<br />
....<br />
}<br />
bool next() { .... }<br />
T* get() { .... }<br />
<br />
....<br />
};<br />
<br />
class CMyClass1;<br />
class CMyClass2;<br />
<br />
CMapList<CMyClass1><br />
CMapList<CMyClass2><br />
