But the compiler says there is no window??hmmm...
The dialog is already created so why this error message??
It's true that the C++ object of the dialog is created but not the window. The window will be created when you call something like dlg.DoModal();
As for the 2 dialog issue, you can save the pointers of the first dialog in the 2nd one and thus once the 2nd on is displayed, you have the access to all of the controls in the first one.

CDialogOneDlg dlg;
dlg.btn.SetWindowText("TEST");
there you create a new CDialogOneDlg. You must get a pointer to you'r previous CDialogOneDlg, (CDialogOneDlg* dlg) and for this you will have to do something like
CDialogOneDlg* p_dlg;
p_dlg = (CDialogOneDlg*)this->GetParent();
p_dlg->btn.SetWindowText("TEST");

this might help
COleVariant ov;
...
ov.ChangeType(VT_BSTR);
char ansiFilename[MAX_PATH + 1];
if (WideCharToMultiByte(CP_ACP, 0, ov.bstrVal, -1, ansiFilename, MAX_PATH, NULL, NULL))
{
ansiFilename[MAX_PATH]=0;
...
}
else
{ error }
#define O 0.05
#define I(c) putchar(c)
main(){int I(int);double l[6];char lO[5];for(*(lO+1)=0;*(lO+1)<'2';I(0x0A),(*(l+5))=-25*O+((*(lO+1)
)++)*O)for((*(lO+2))=0;(*(lO+2))<'2';(*(l+4))=-40.*O+((*(lO+2))++)*O){for((*(l))=(*(l+1))=0,
*(lO)=1;++*(lO)&&(((*(l+2))=((*(l))*(*(l))))+((*(l+3))=((*(l+1))*(*(l+1))))<4.);(*(l+1))=(*(
l))*(*(l+1))+(*(l+5))+(*(l+1))*(*(l)),(*(l))=((*(l+2))-(*(l+3)))+(*(l+4)));I((*(lO)?42:0x20));}}

I've always used V_BSTR or V_BSTRT macros.
COleVariant ov;
CString x;
ov = ...;
x = V_BSTRT( &ov );

I've modified the "IDR_MAINFRAME" and the "IDR_MYAPPTYPE" Icon but the modification are not show at run-time... I always see the MFC Icon dans the default Document one. Why?

Each icon ID consists of two icons- a 32x32 and a small 16x16. Theres a combo box in the icon editor to select between them. Chances are you've only changed the large one, but its actually the small one that is used in most situations. Edit those and rebuild.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

Hi, I`m just starting to develop some TWAIN compatibility in my program for scanners etc. but I haven't got a clue where to start, can anyone give me some good links to the information I would need to successfully implement TWAIN? I would obviously prefer somewhere that offered it for free.
Many Thanks,
Alan.

EZTWAIN (http://www.dosadi.com/eztwain1.htm) is free. you might give that a look.
-c
#define O 0.05
#define I(c) putchar(c)
main(){int I(int);double l[6];char lO[5];for(*(lO+1)=0;*(lO+1)<'2';I(0x0A),(*(l+5))=-25*O+((*(lO+1)
)++)*O)for((*(lO+2))=0;(*(lO+2))<'2';(*(l+4))=-40.*O+((*(lO+2))++)*O){for((*(l))=(*(l+1))=0,
*(lO)=1;++*(lO)&&(((*(l+2))=((*(l))*(*(l))))+((*(l+3))=((*(l+1))*(*(l+1))))<4.);(*(l+1))=(*(

Thanks Chris, its just what i need. I have, since asking the question, also managed to find a TWAIN wrapper on this very site, for anyone wanting an alternative.
Many Thanks Chris,
Alan.

Your signature seems to be the DeCSS source, right?

Sorry, don`t know what you mean by "DeCSS source", so i`ll have to say no and let someone else claim credit.

I am having problems adding a dialog to a static library.
I have created a static library with MFC support, and then went to the menu and selected insert/resource which gave me a dialog to work with. However I want to assign a class to the dialog and do things with it, but The class Wizard option is unselectable. any ideas please??
cheers

Hi
What's the easiest way to start an application and wait until it has finished?
Should I use ShellExecute or CreateProcess?
And should I use a timer to check if the app has finished or is there a better way?
regards
|
|
|
|
|
Use WaitForSingleObject with a handle returned by CreateProcess. ShellExecute doesn't return the handle, but you can use ShellExecuteEx.
Your thread will be stopped until the spawned process runs.

I'm a bit confused about the use of ADO and the use of SQL. I have an application that uses a database, which database depends on the users configuration but almost always it's either MSAccess or MSSQL or Oracle SQL server. I have up till now used a sql string to create a recordset but now I'm beginning to wonder if this is the way ADO is meant to be used.
If someone would explain the pro and cons of using SQL contra 'ADO internal' I would appreciate it!

Is this a bug?
I tried this function overloading with Turbo C++ 3 & VC++ 6 and both produced the same error of ambigous call:
float Op (float X, float Y, float Z)
{
...
}
int Op (int X, int Y, int Z)
{
...
}
1) Op (3.0, 6.0, 9.0);
2) Op (3, 6, 9);
The compiler said that the (1) function call is ambigous despite the fact that the parameters have decimals. I tried this:
3) Op (3.1, 6.1, 9.1);
with the same result. But by specifying even the first element's type, the compiler did not complained (and called the correct function):
Op ((float) 3.0, 6.0, 9.0);
How come the compiler does not recognize the decimals of the parameter as float? Also after placing decimal values > 0 (as in the (3) function), the compiler still would not consider the parameters as float.
Is this a BUG?
