Well, this is a definite no-no from worker threads.
Never touch the GUI from a worker thread, it may cause a deadlock.
Read Joe Newcomer's article on the subject to get a better understanding of how to do worker threads here[^].

Just opened the readme to VseDebug it says it works with
Visual studio.net 2002 2003 Anyone know if you can build it With Visual Express 2005

The following code on a linux gcc compiler gave me an error message:
error - SO C++ forbids declaration of "vector" with no type
apparently,
vector <double> dd; is okay because double is a known type
How can I make g++ recognize t_vertice as a valid type?
Or how can I switch off the ISO compatibilty on the g++ compiler?

Can modify your code with ignore html tags option ? So that it can be readable, understandable.

I've never worked on linux.
But, just a suggestion. Can you try, moving this typedef outside the class ?

no go, still same error message

I've never used gcc but searching on the error message it seems the likely culprit is
"vector" is not defined, usually because of a missing header or a namespace problem.
If you have the right header(s) included, maybe "std::vector" will work.
std::vector <t_vertice> puntos;
or
using std::vector;
...
vector <t_vertice> puntos;

AttachThreadInput() and set window by SetFocus().
sample:
<br />
BOOL SetWindowActive(HWND hActivedApp)<br />
{<br />
HWND hWnd = NULL;<br />
hWnd = GetForegroundWindow();<br />
DWORD FormThreadID = GetCurrentThreadId();<br />
DWORD CWndThreadID = GetWindowThreadProcessId(hWnd, NULL);<br />
if(FormThreadID != CWndThreadID )<br />
{<br />
AttachThreadInput(CWndThreadID, FormThreadID, true);<br />
}<br />
<br />
if( ::IsWindow(hActivedApp) )<br />
{<br />
SetFocus(hActivedApp);<br />
return TRUE;<br />
}<br />
<br />
if(FormThreadID != CWndThreadID )<br />
{<br />
AttachThreadInput(CWndThreadID, FormThreadID, false); <br />
}<br />
return FALSE;<br />
}<br />

Do I call this function on the oninitdialog function or other events?
thanks for the code....

any time except in hook proc.

App a is running in focus painting the Window Banner with progress counts, when an email notice pops
up...after that the running app doesn't paint the window anymore even though it runs to completion...same thing happens when you minimize the running apps window...is there an easy gracefull way to solve this... I've tried 'invalidating ' stuff but its jerky and seems very inefficient...thanks in advance.

Are you drawing in response to WM_PAINT?
Are you preventing the UI thread from processing WM_PAINT messages?

Hmm... I'm actually letting the virtual onpaint do the painting....how can I detect if I am preventing the UI thraed from receiving the msg....this whole thing seems like it ought to be trivial....i just want the original window to repaint after having been overwritten/minimized....how do other apps do this...thanks.

OnPaint is virtual? I thought there needed to be a message map entry for WM_PAINT for the window
class.
Anyway, if your painting works fine when you don't do any lengthy processes in the background, but
when you have something going on in the background it stops painting then that probably means
your message loop is tied up.
Possible ways to correct this are:
1) do lengthy operations on a separate thread
2) Periodically pump all messages from the message queue while doing a lengthy process on the UI
thread.
3) Use Invalidate()/UpdateWindow() to force an instant WM_PAINT message (bypassing the queue)
(this doesn't really help in your case because you don't know when you need to repaint).
It should be trivial, yes, but not if you're UI thread is off doing something else

Hello everybody im getting an error that says LPENUM_SERVICE_STATUS pess = malloc(cbBytesNeeded); cannot be converted from void * to LPENUM_SERVICE_STATUS. This code is very old and I know 100% it worked with my old C compiler. Any help would be appreciated. Using VC++ 7 and windows XP. Thanks in advance
|
|
|
|
|
Try this:
LPENUM_SERVICE_STATUS pess = static_cast<LPENUM_SERVICE_STATUS>(malloc(cbBytesNeeded));

Hi All,
I would like to find out if there any way to change the path for the swap(pagefile.sys) file. In particular i want to be able to change the partition in which the pagefile resides.
Is there a sample code, blogs, article or function can I see?
Thanks,
|
|
|
|
|
Programmatically? Maybe using WMI (see the Win32_PageFileSetting[^] class).

I have dialog in MDI with a simple text box that i want to change and update the text when a button is clicked. I I can't remember how to update the text box. I have the following code for the button press.
void CNeuralNetTwoView::OnBnClickedButton1()<br />
{<br />
<br />
UpdateData(true);<br />
ScottsTextBox = "JERNIE CORPORATIONS";<br />
<br />
ScottsTestBoxCtrl.UpdateData(true);<br />
<br />
UpdateData(true);
<br />
UpdateData(FALSE);
<br />
}<br />

Assuming ScottsTextBox is a CString associated with the control (using DDX)...
void CNeuralNetTwoView::OnBnClickedButton1()
{
ScottsTextBox = "JERNIE CORPORATIONS";
UpdateData(FALSE); // Transfer data from variables to controls
}
or maybe ...
ScottsTestBoxCtrl.SetWindowText("JERNIE CORPORATIONS");

You've posted this to every board I have visited. Please don't. If you're using VB, what will you do with an answer in C+ ?
