listView1->Dock = DockStyle::Fill;
listView1->View = View::Details;
listView1->FullRowSelect = true;
listView1->Columns->Add("Col1", 100);
listView1->Columns->Add("Col2", 100);
ListViewItem ^lvItem = gcnew ListViewItem();
ListViewItem::ListViewSubItem ^lvSub1 = gcnew ListViewItem::ListViewSubItem();
lvItem->Text = "Cell1";
lvSub1->Text = "Cell2";
lvItem->SubItems->Add(lvSub1);
listView1->Items->Add(lvItem);
ListView::ColumnHeaderCollection ^test = listView1->Columns;
Int32 test1 = test->IndexOfKey("ID");
MessageBox::Show(test1.ToString());
And it is still same. I get -1

Because your columns are called "Col1" and "Col2" not "ID"
System.IO.Path.IsPathRooted() does not behave as I would expect
|
|
|
|
|
Did you tried example?
In that example i made typo, but even if i change "ID" to "Col2", the result is same.

Nope, dont have time to do that today
Do the columns appear on the screen?

Yes everything was ok, except i cant get Index key for specific column.
|
|
|
|

Found a workaround this problem:
MessageBox::Show(listView1->Columns[1]->Text);
If i used it in the for loop, i coud get index ot the columns

Guys,
I'm trying a little test app in C++. I added a button and an event handler for this button.
I'm creating a test app that has to call some dll functions in late binding. Although I have done this before I tried to do a simple AfxMessageBox just to get the hang of it again. And it fails (yes this line: AfxMessageBox("Test"); fails. Even CString test = "My test here."; fails.)
so what did I forget? (I made a MFC app via the wizard, it gave me an error when adding the control variable for the button, but the rest it did just fine). MSDN says I have to do it like this. (and my memory, pray to God it didn't fail me, says so too;P)
the error message I get is :
Error 1 error C2440: 'initializing' : cannot convert from 'const char [9]' to 'ATL::CSimpleStringT<BaseType>' d:\projects\projects c++\loaddlltest\loaddlltest\loaddlltestdlg.cpp 92
tnx...

AfxMessageBox(_T("Test"));
CString test = _T("My test here.");

works idd, I'll have to look up why some day  .
tnx

I think it is just because the default project settings in VS2005 is UNICODE.

BOOL WriteFile(
HANDLE hFile, // handle to file to write to
LPCVOID lpBuffer, // pointer to data to write to file
DWORD nNumberOfBytesToWrite, // number of bytes to write
LPDWORD lpNumberOfBytesWritten, // pointer to number of bytes written
LPOVERLAPPED lpOverlapped // pointer to structure for overlapped I/O
);
When using this function and it's return false (failed) can i rely on lpNumberOfBytesWritten value?
(no answer in MSDN)

Really? In the documentation [^]it says:
Return Value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

I asking something else, Can i rely on LPDWORD lpNumberOfBytesWritten,
parameter in case of failure

g_sasha wrote: in case of failure
don't you think that might depend on what the error from GetLastError is?  Why have you not posted the Error information?
led mike

There is no error (yet), i dont think it's depend on GetLastError, i think it's should be just yes/no answer.
Can you think of example where it may be depend on error ?

Probably a bad idea. And you're asking in the wrong forum

Hi all,
I am writing a console app which will in turn run a windows application then simulate sending keyboard command to the application.
I have been able to run the app and get it's handle and all that - every thing here is fine.
To issue keyboard command I will have to use the
SendKeys::SendWait("%F");
The '%F' simulates the Alt-F to access the menu.
Seeing that SendKeys is a member of the System::Windows::Form namespace I have to include this in my code, which I have done like this:
<br />
#using "System.Windows.Forms.dll"<br />
using namespace System::Windows::Forms;<br />
When I then compile the code, I get the following errors:
: error C3083: 'Windows': the symbol to the left of a '::' must be a type
: error C2039: 'Forms' : is not a member of 'System'
: error C2871: 'Forms' : a namespace with this name does not exist
: error C3083: 'Windows': the symbol to the left of a '::' must be a type
: error C3083: 'Forms': the symbol to the left of a '::' must be a type
: error C3083: 'SendKeys': the symbol to the left of a '::' must be a type
: error C2039: 'SendWait' : is not a member of 'System'
: error C3861: 'SendWait': identifier not found
So, what have I done wrong and how is this rectified ??

you don't need to use #using "System.Windows.Forms.dll"
yust by adding namespace, you aotomaticly add references

Dou you men like this:
menu1->Text = "&File"; // ALT-F
menu2->Text = "&Edit"; // ALT-E
menu3->Text = "E&xit"; // ALT-X

Ok..... I have now taken out the line:
<br />
#using "System.Windows.Forms.dll"<br />
And now just using:
<br />
using namespace System::Windows::Forms;<br />
But still when compiling I get the following errors:
<br />
: error C3083: 'Windows': the symbol to the left of a '::' must be a type<br />
: error C2039: 'Forms' : is not a member of 'System'<br />
: error C2871: 'Forms' : a namespace with this name does not exist<br />

Have you added a reference to the "System.Windows.Forms.dll" ?
If not, reference this dll in your project and then try compiling the code.
Hope this might help you.

G'Day Girish,
Yea, I had that in my original code:
<br />
#using <System.Windows.Forms.dll><br />
and also had:
<br />
using namespace System::Windows::Forms;<br />
But I was told to take the top line out as the namespace will reference the DLL.
But when I compile either way I still get that same error code.

go to menu:
Project->(Your Project Name) Properties->Common Properties
On the right you will see references And you can click Add Reference.
Other oproblem coud be: Under General, look if you have Common Language Runtime Support. As long as you have with /clr
Third possible. You can have problem with a code. If so then try to add a comment to all includes.
If you have a problem with client, yust to be same make an test project. But this namespace would automaticly be in use

G'Day bsaksida,
Have a look at my reply to Girish......
Thanks for the hand on this.

Hi Pete,
I am not sure whether you got my query correctly.
Try this ,
Right click on the Project and Choose References. Then Add reference to "System.Windows.Forms.dll".
Try to compile your code after you have added this line
using namespace System::Windows::Forms;
Compile and check if it works.
If this does not work, then please post your code snippet..
Thanks & Regards,
Girish K
