How do I get a HANDLE of the other app?
Is WaitForInputIdle((HANDLE)wnd,INFINTE) legal?
This did not solve my problems, but you might take a look at my comment "Just found strange behavior" I hope you understand it, my English is not very good 
thanks

No, you can't just use HWND as a process handle. For that you'll need to use ShellExecuteEx or get the handle with a call to GetWindowThreadProcessId/OpenProcess.

BTW: you'll have to change FindWindow to EnumWindows. That's because your app may be started twice, and it may launch two (or more?) apps with ShellExecute. FindWindow will find first HWND with given class/caption - this criteria is too weak if you can have more than one app launched with ShellExecute.

It looks like synchronization problem. Your 2nd FindWindow call finds the main window launched by 1st ShellExecute call, then sends the message. Message is processed OK and item is selected.
It seems that launched app needs some time before it can accept messages - WaitInputIdle ensures that. Use ShellExecuteEx to avoid problems with mutliple target windows - you'll get the process handle. You'll also have to abandon FindWindow - if two apps were launched, the find criteria are too weak. EnumWindows and GetWindowThreadProcessId are the way to go.

I need to handle a 2D Array whose first subscript is known to me only at runtime.The Array is an array of strings.The second subscript is the max size of a string.But I want to use only character arrays but not CString to represent a string.
Hence,if I declare an array,like
#define MAX_STRING_SZ 10
char MyArray[][MAX_STRING_SZ+1];
...
and I want to use the above array in a function F1.
F1 will return such arrays , n numbers,to function F2,where The arrays's members are shown in a list view.
But,the array declaration is not allowed in Microsoft Visual C++ to have empty braces[] as well as with any variable,whose value I would supply as and when I get.
I am in urgent need of this.
Thanking you ,The Experts,in advance!!!

Can't you use CStringArray, CStringList or std::vector<std::string> ?

First of all, I'd recommend forgetting about 2D arrays and going to something more high-level like, for instance, a std::vector of std::strings. Anyway, if you can't afford it, the syntax you must follow is like this:
void F2(char array[][MAX_STRING_SZ+1],int len); Here len is needed to inform about the first dimension of the 2D array. To define a variable capable of holding 2D arrays of unspecified (i.e. determined at run-time) first dimension, the syntax is:
char (* MyArray)[MAX_STRING_SZ+1]; which is also the return type of your F1 function. Remember, the first dimension must be passed along somehow. And please allow me to recommend you again that you use STL containers to make your life easier.

Why RichEdit20A scroll the contents of the CRichEditCtrl in view ?
For example, I wrote handler for ON_WM_VSCROLL():
[ccode]
void CRichSyntaxView::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
// TODO: Add your message handler code here and/or call default
CRichEditView::OnVScroll(nSBCode, nPos, pScrollBar); //call std handler
CRichEditCtrl& r = GetRichEditCtrl();
CHARFORMAT2A cf;
CHARRANGE ccr;
memset(&cf,0,sizeof(cf)); // clear
r.SetRedraw(false); // don'n redraw
r.HideSelection(true, true); //don't show the selection
r.GetSel(ccr); //save old selection
r.SetSel(iMin, iMax); //set new selection
...
r.SetSel(ccr); //restore selection
r.HideSelection(false, true); //show the selection
r.SetRedraw(true); //redraw=on
Invalidate(false); // refresh view
}
[/ccode]
In Richedit 1.0 all ok. Why?
=== MSDN98 ===:
SetSel(..)
The caret is placed at the end of the selection indicated by the greater
of the start (cpMin or nStartChar) and end (cpMax or nEndChar) indices.
This function does not scroll the contents of the CRichEditCtrl
so that the caret is visible.
RichEdit20A - glucked..
Please help me!
thank you..

I´m creating a new app that needs to export some data to excel. It´ll be a WEB app, the user will click on a link that will activate an ISAPI Extension written in VC++ that will send the data as an xls file. My question is: do I need a copy of Excel installed on my server to export the data or there is some other way ?

If you export your data as a CSV (which excel knows how to read), you will not need excel.
(2b || !2b)

Depends that you need, If you want, you can make csv files, with coma separated or you can make excel files, using ole automation, for this you need the excel installed on your sever...
Also if you want, you can write excel file knowing the Excel format, for this you can see it here

One more question. Let´s assume that I create my program exporting to excel even if the user doesn´t have Excel installed. Question: Is it legal ? Can I use the file format of a MS program ?

Really, I don't Know, I believe that your application need a license for use xls format, I think that you need to comunicate with the people of M$ support. I belive that the licensse must be cheap...
May be if the server have a excel installed and you work through OleAutomation, you have the problem solved quickly, (the format and the licensse). Anyway I has problems with oleAutomation, sometimes I got the error "The server is busy...." but with a loop you can solve that...
Best Regards!!!!

This response may be too late, but you could always create a comma or tab delimited file with the file extension .csv . This format is read natively by Excel.
Best Regards.

Hi,
I want to communicate with parallel port(bi-directional).
Please suggest me a method. if possible give me the code.
thanks ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Use CreateFile("LPT1",...) and then regular ReadFile and WriteFile on the handle obtained. Check Parallel Port Central for further info.

how can i initialize a indirect bass class using constructor?
example
class A{
public:
int i1
A(int i){i1=i;};
};
class B:public A{
public:
int i2
B(int i){i2=i;}
};
class C:public B{
public:
int i3
C(int i){i3=i;}
};
main(){
C* p = new C(1) // how to initialize A::i1 and B::i2 here?
}
|
|
|
|
|
C and B have to provide the means to initialize base classes B and A, respectively. You can write constructors like this:
class B:public A{
public:
B(int i,int j):A(j){i2=i;}
...
};
class C:public B{
public:
C(int i,int j,int k):B(j,k){i3=i;}
...
};
...
main(){
C* p = new C(1,2,3);
}Hope you get the idea.

It there no direct way to initialize multi-inherit base class?
I get your point, but i guess such a mature language like c++ should have more effect way to do that.
thank u after all.

|

|

No, the only way to initialize base class(es) of a given class is by using the constructors provided by the class1. This has some motivation, though: it is the responsibilty of a class to maintain internal consistency among its members and base classes, so it is wise to let this class restrain construction of base classes (and even access, for that matter) to implement the particular logic suitable for the context in which these subobjects are used.
1When defining a ctor for a class, under certain special circumnstances (namely virtual derivation) you can directly call constructors from classes that are not direct bases but rather lie farther up the hierarchy. This is a rather messy subject, though, and often it doesn't work as first expected.
