are you sure it is not a declaration before a definition instead of a type ?! (in C++, it is like that...)

Thanks for the replies guys. The error line reads:
error C2061: syntax error : identifier 'cDataFile'
Where cDataFile is a class defined in another header file which I have included in this header file
The function definition (part of another class)
void Save(cDataFile*);
So I'm stumped

First, make sure that cDataFile is spelled correctly (including capitalization, I am suspicious of your lowercase 'c').
Second, when your function uses a pointer to a class, as you did, you only need to forward include the class in the header file. Then put the #include in the .cpp file (not the .h file)
i.e.
class cDataFile;
class CYourClass
{
void Save(cDataFile*);
};

Thanks for the continued help...I seem to be a bit confused though...the spelling is correct (I always use a lowercase c for classes)
Here is my file structure/layout:
Header1.h
---------
class cDataFile
{
...
};
----------
Header2.h
---------
#include "Header1.h"
class cSomeClass
{
public:
void SaveSomeFile(cDataFile*); <---- This is were I get the error
};
----------
Could you please explain what you said before in this semi-diagramatical way? Thanks.

hello, I was just wondering is it possible to include a dll in the resources of a exe and then when the exe starts maybe copy them in the exe's directory(programaticly) and use them from there(I mean so that the exe can load the required functions from these dlls).
Or can dll functions of dlls inclouded as resources be called from the exe, I don't think they can.
Thank you for your time.
please reply

You can include the DLL as resource, extract it at runtime and then do anything you like with the DLL, like LoadLibrary, GetProcAddress etc

You can do that, although it's somewhat of a pain. You simply add the DLL as a custom resource at build-time. At run-time, you get the binary data for that resource and save it to file, then you can LoadLibary on the DLL and run its functions.

Actually it's pretty easy. I'll share my code with you (isn't that the purpose of this forum?  )
<br />
UINT dll_size;<br />
void* dll = NULL;<br />
void* LoadDatFromResource(HINSTANCE hModule);<br />
dll = LoadDatFromResource(hInstance);<br />
<br />
void ExtractFile()<br />
{<br />
if(dll == NULL)<br />
{<br />
return;<br />
}<br />
<br />
FILE *outfile;<br />
if (outfile = fopen("file.dll", "wb"))<br />
{<br />
fwrite(dll, 1, dll_size, outfile);<br />
fclose(outfile);<br />
}<br />
}<br />
<br />
void* LoadDatFromResource(HINSTANCE hModule)<br />
{<br />
HRSRC hResInfo;<br />
HGLOBAL hRes;<br />
<br />
hResInfo = FindResource((HMODULE)hModule,MAKEINTRESOURCE(IDR_ID_DLL),"ID_DLL");<br />
if(hResInfo == 0)<br />
{<br />
return NULL;<br />
}<br />
<br />
hRes = LoadResource((HMODULE)hModule,hResInfo);<br />
if(hRes == 0)<br />
{<br />
return NULL;<br />
}<br />
<br />
LPVOID pDatabase = ::LockResource(hRes);<br />
if(pDatabase == 0)<br />
{<br />
return NULL;<br />
}<br />
<br />
dll_size = SizeofResource((HMODULE)hModule, hResInfo);<br />
<br />
return pDatabase;<br />
}
dammit, where are the tabs gone in the code?

Hi,
I want to add to my program something similar to the Microsoft Office paperclip guy and the popup balloon messages (hopefully in a way that is not as annoying . I'm not sure where to start looking. Is this a standard control? If yes, what is it and if not, how might I go about implementing one like what controls/classes might I need. I'm kinda lost.
Thanks for any input!

Thanks! I'll try not to be annoying in my program LOL

No, you don't. You will incur much wrath; look at the reaction the Office paperclip has gotten over the years.
Well ok, if you must do it, that character is called the Microsoft Agent.

Add the Microsoft Agent ActiveX Control to your project. In the resource editor, add the control to the dialog template, and assign it a member variable. Then use the following code:
m_AgentCharacters = m_agent.GetCharacters();
m_AgentCharacters.Load("Robby", _variant_t("robby.acs"));
m_AgentCharacter = m_AgentCharacters.Character("Robby");
m_AgentCharacter.Show(_variant_t());
m_AgentCharacter.Speak(_variant_t("My name is Robby"), _variant_t());Customize as needed!

Hi, I have some doubts about doing a non-standard interface application. I want to do an application like Winamp (with an image in the background). I know how to put this image at background of dialog (bmp image) but i want to erase the background color to make it transparent (for example, do white colour as transparency colour). Does somebody know how to do it easyly? I've found interested Skinnable applications in CodeProject, but I just want to do this in few lines.
Thanks.

Hi..I think this is the only way..
One thing you can do is load bitmap at runtime & create mask from that using program. Then that means what ever bitmap you provide it get looks like that..
OK! Good Bye

Thanks Sumit, I think you want to say that I have to apply a Region in my dialog with the form of my bitmap? or something else?
|
|
|
|
|
yes..Dear..
Just apply bitmap at runtime & create region at OnSize() & apply that region at OnPaint()...
this is only source I think..
OK! Good Bye..Keep trying success is just one step ahead..

I have 2 radio button groups within their own group box. The first radio controls in each group has its group property checked. OnInitialUpdate(), the first button in each group is checked by a call to CheckRadioButton as seen below.
CheckRadioButton(Group1Button1, Group1Button3, Group1Button1);
CheckRadioButton(Group2Button1, Group2Button3, Group2Button1);
All is fine and dandy when these buttons are not acting as controls. When they are it causes all sorts of problems. For example, when I click on the second button in either group, a modal dialog appears prompting input. When cancel is clicked, it defaults to the first button through a call to OnGroup1Button1(). Within that function lies CheckRadioButton(Group1Button1, Group1Button3, Group1Button1). When CheckRadioButton is called it clears all the other radio buttons in the other group as well. Another problem that arose was the fact the modal dialog box keeps reappearing when you leave and return to the application.
What could be causing CheckRadioButton to act this way? Any help would be much appreciated.

Are the IDs of each button contiguous? In other words, do you have something like:
#define GRP1BTN1 100
#define GRP1BTN2 101
#define GRP1BTN3 102
#define GRP2BTN1 200
#define GRP2BTN2 201
#define GRP2BTN3 202 Or are the numbers in some other "random" order?

That did it. At first I thought the tab order would handle it but I guess it didn't. Thanks a bunch David!

Methods and macros that rely on contiguous control and command ids lead to unmaintainable code and hard to find run-time errors. They don't pass our code reviews.
