Would you agree that bit of code should set the text color for each row in the report based on the return value of the COLORREF function?
Well..no! The SetTextColor() / SetBkColor() functions applies to the entire control, not just to an individual item within.
If you require individual control over the color and/or fonts used by row and column then have a look at Custom Drawing techniques. This[^] is a good starting article.

Just to prove to myself I wasn't going mad and that you CAN use settextcolor for individual entries in the list, I added a button which, when clicked, inserts an item into the list in green. It works fine (and the rest of the list stays in the color it was).
Beats me This should not happen, but see below:

I had the app open on one monitor while stepping through it on the other, and the list control only shows the items once they've all been added.
Makes sense as the drawing routine would not have been called while tracing through your code.
m_dale wrote:
In other words, setting the redraw flag to true should mean the list control updates each time something is inserted. Not so. It appears both of those statements are simply ignored.
Although I cannot be sure, I would guess that while you are in debugging mode, the usual process of pumping and processing the usual windows messages (that are responsible for your control window updates), are in stasis; therefore you cannot expect normal window actions to be performed while this is happening.

Only once have I been able to get it to do what I want, under very specific conditions. If:
* I call myList.SetColumnWidth(someCol, LVSCW_AUTOSIZE);
and
* The data width in someCol requires the column to be resized
THEN it will work.
Obviously this is useless, as it requires each entry in someCol to be longer than the last in order to get the desired effect.
As I said above, once the window has been allowed to process its usual messages, then you will get the results you expect, but while tracing through your frozen program, one line at a time, this is expected.

Ah, looks like i was being stupid.
When I drag another window over my funky multicolored list it redraws in the last color selected.
Custom drawing here I come...

Is it possible to detect if a mmodem is currently connected/ in use etc.
If so how?

Thanks for your prompt reply.
I'm not sure if that's what I want really.
What I really want my app to do, is watch the modem for a remote connection (company dialling in), then when it sees a connection, to disable the LAN.
Obviously when they disconnect to re-enable the LAN.
Thanks

Hello,
i try to put a working code snip from an mfc .exe project into a .dll project. In the code an EVENTSINKMAP is linked to an activex control in my "old" mfc exe. The .dll should start working when an event occures from this activex control:
BEGIN_EVENTSINK_MAP(CSavepmjxApp, CWinApp)
ON_EVENT(CSavepmjxApp, IDC_SCANCONTROL, 1 , OnScanReadyRealscan1, VTS_UNKNOWN)
END_EVENTSINK_MAP()
The compiler gives an error because IDC_SCANCONTROL is unknown in my .dll project.
I like to use this .dll later in VisualBasic where i have my activex control again. How can i make this work??
happy coding,
-mark

I have failed to set the bi-directional bit of the parallel port using the "inpout32.dll". Each time I write to the control port a value that would translate to setting the bi-directional bit to "1", the value that is ultimately written is one which does not set the bi-directional bit. E.g. writing "32" to the control register which would translate to the bi-directinal bit being set to "1", results in "192" being written to the control register. "192" is a value which when converted to binary results in the bi-directional bit not being set. Any idea to what the problem might be?
So help me God!

I'm building a treeview in a virtual CListCtrl, i've got almost everything working except for one thing:
When you click an item in a listview it gets selected on the mouse down.
When you click a node in a tree view it gets selected on the mouse up.
This means that when you drag an item from the listview you're always dragging the selected item.
But in a treeview you can drag an item that is not the current selected item. And when you're done dragging the selected item becomes active again.
So what i'm looking for is a way to disable the item select in a listview on the mouse down.
Can anyone help me?

In C++ language, is there a command to convert ASCII to HEXADECIMAL value? Like 'atoi', whereby this is a conversion from ascii to ingteer !!!! So, anyone pls know, pls reply. Thanks!

Have a look at
this[^] thread. You might also want to try searching previous post if this doesn't help.
If all else fails, clarify your question and we should be able to help further.

There's no such thing as converting ASCII to hexidecimal. One is not like the other. Perhaps you wanted to know how to convert from base 10 to base 16.

Hello Techies,
How can I retrieve the path from where the application is being executed? This path should be retrieved at the initialization process itself.
Thank you,

Use GetModuleFileName , passing NULL in for the hModule parameter.
|
|
|
|

Thank you Graham, But when I used the above function in the following way
GetModuleFileName(NULL,LPTSTR(path),1000);
It gave me an memory exception mentioning that it cann't read the memory.
path is a type of char pointer.
I had declared path as char* path;
|
|
|
|
|
It sounds as if you haven't allocated the memory - GetModuleFileName won't do that for you.
Try:
char path[1000];<br />
GetModuleFileName(NULL, path, 1000);
This statically allocates 1000 characters for the path variable.

Hi Graham,
Thank you for ur suggestion, its working, but its retrieving the file name also. I want to know only the path. For eg., If the application is present in C:\my document\Testing, then its displaying as C:\my document\testing\Test.exe
but i want to display only C:\my document\Testing. The application file should be displayed.
Bye
Thank you once again
Regards,

The easiest way to do this is to parse the returned string and find the last '\'. If you terminate the string there you will get just the path as you require.

You should process yourself. Just find the last \ and extract the left before that.

use _tSplitPath api,that may help you in above cause
and for removing '\' use CString::trimRight function
