Can't create a DLL dialog box object

Hi
I created a Dialog box class within a MFC share Regular DLL. I use the Resource Wizard to create the Dialog and Class Wizard to define the derived class. I'm exporting the class with the _declspec(dllexport) storage class type specifier.

When I try to create an object of that derived Dialog box class in the client application... the object pointer is NULL. I get no errors. The DLL is loaded at load-time, the DLL Library is included in the linker. Do you know what step(s) I might be leaving out ??

One person suggested adding the AFX_MANAGE_STATE macro... but, none of the CDialog base functions are being re-defined. So, I'm exporting the Dialog Box functions indirectly... adding the AFX_MANAGE_STATE macro at the begain of the exported functions is not feasible. Besides, I create a Regular MFC DLL function that used a device context pointer and CBrush class... and I did not include the AFX_MANAGE_STATE macro.

Thx,
King

Hi
I try adding that code to the client app and hRes is a NULL HINSTANCE pointer.

also, I'm not sure where the problem lies, in the DLL or the Client ??

UDP-protcol in C

Hi!

Somebody that have programmed an UDP-protocol in C or C++? I need to do so but I am not sure how to. I have been reading a lot about how UDP works and how it looks like, but still to make C-code is little bit complicate..

Anyone that can help me? Is there any open-source that I can look at? I can´t use win-sockets because I use a laborationsboard that don´t have any common OS. So I need to write it in C?

ASCII Sort routine

I need to do some sorting in a C-Scripting environment.

I have an array of string; e.g. "Fread2", "RobertThree", so just need a routine that will determine if string1 > string2.

I know I could write my own, but I bet it would be slow and I am sure that it has been done many times before.

Sweep.

PS The scripting environment has no Sort routines!

CFileDialog in windows service

douglas_kei23-Jun-04 4:44

23-Jun-04 4:44

I am using a windows service program to open a CFileDialog. The file dialog box can be displayed and working.

However, when the choosing the Desktop folder, it goes to the "C:\Documents and Settings\All Users\Desktop" instead of the Desktop folder of the logged on user. When choosing the My Documents folder, it goes to the "C:\Documents and Settings\Default User\My Documents" folder instead of the logged on user's My Documents folder.

When clicking the New Folder icon, the newly created folder does not displayed unless F5 is pressed. When renaming/deleting folder, the displays update only after press F5.

When i use the same code to call CFileDialog in a non-service application, it works perfectly.

Can anyone help me to solve the problem?
Thx!!

Most of services are running udner SYSYTEM account, but not under logged user account. This account has no "user folder", so it drops you to default user folder.

Yes, i know about this. But the question is, how can I set the service process environment so that CFileDialog works as if it is called by logged on user. Thx!

No trick, just use InsertString().

Class inheritance problems

Hi!

I can't derive my CBaseRenderer class from CD3DBase, here's my code:

#pragma once

class CD3DBase;

class CBaseRenderer : public CD3DBase
{
public:
	CBaseRenderer(void);
	~CBaseRenderer(void);

public:
	void OnLostDevice();
	void OnResetDevice();
	void OnFrameMove();
	void OnRender();
	void OnInitVolatileResources();
	void OnFreeVolatileResources();
};

and these are the errors:

------ Build started: Project: DXProject, Configuration: Release Win32 ------<br />
<br />
Compiling...<br />
CBaseRenderer.cpp<br />
e:\C++\DXProject\CBaseRenderer.h(7) : error C2504: 'CD3DBase' : base class undefined<br />

What's wrong with this code? Frown | :(

You must include the header for the definition of CD3DBase. If you are deriving from a class then it is not enough just to have a forward reference, you need the full class available.

Ok thanks, but if I include the header, I get even more errors, since CBaseRenderer and CD3DBase include each other, because CD3DBase needs to create an object of CBaseRenderer

You could put a forward declaration of CBaseRenderer into CD3DBase.h

You're missing #include "BaseRenderer.h" or you can make gRenderer a pointer.
