How can I get a pointer to a CDC inside a Form's paint method?
- A programmer's national anthem; "AAAAAHHHHH!!!!"

In the OnPaint method:
if (IsIconic())<br />
{<br />
}<br />
else<br />
{<br />
CPaintDC dc(this);
CDialog::OnPaint();<br />
}
this is this.

Hi,
I am currently working on a project where I would like to have an embed chat window. Since I would like it to be embedded within an SDI application, that means that I don't want multiple chat windows to be able to communicate with different ppl.
I would like to have some sort of control where I can switch between list box controls (what I am using as the 'chat message pad') using tabs. I know that there is already a tab control, but it doesnt really have everything I need.
I would like to have tabs on the left side, with horizontal text. I would also like each tab to have a close button [x], and for tabs (and new pages with list controls) to be able to be added programmatically during runtime.
Does anyone have such a control or can recommend a good place to research?
Any suggestions will be greatly appreciated,

given a string containing hex,is there any function that checks if teh given string holds a valid hex value?
cheerz!
|
|

|

Not directly. It's fairly easy to write one though. Just check that there is nothing other than 0-9 or A-F in the string.

Given the nature of the original question, I chose not to make any assumptions.
We actually had production code similar to the following (greatly paraphrased)...
<br />
if( cChar > 'a' && cChar < 'z' ){<br />
... blah blah blah...<br />
}<br />
I suppose you can already see what is wrong with that, even if they were only looking for lower case characters...

AFAIK, there is no way to check a whole string for valid hexadecial values, but you can make a loop and check each character one by one.
Have a look at one of the isxdigit functions.

Long story short: I have files that are on a windows network that went through another OS initially and have invalid windows filenames. this process of copying the file (unfortunately) does not cause an error leaving the windows machine with files it cannot open or really do anything with.
i am trying to find a way to rename these files and have hit major snags. the file system supports the file name (NTFS) but winxp does not so functions such as MoveFile fail. even the CRT function rename() fails and rightfully so, the name was invalid. this whole thing is pretty stupid considering the FindFile family of functions will return the invalid file name anyways even though the rest of the API doesn't support it.
i dont have the old DOS option but i was wondering if anyone could offer any insight on this issue. the lower level NtOpenFile() and other accompanying functions seem as though they might offer a solution but I cannot find enough documentation (hell, there is almost none) on this to know how they work, go figure.
maybe i need to be at a driver level?
at any rate, it can be done. i've seen programs that claim they are able to do it (making my own is more fun) and even windows will rename the invalid file through the context menu so something in the OS can do this. function hooks aren't telling me anything useful from the Nt funcs so hopefully someone else can.
cheers.

Try seeing if GetShortPathName() works. If it does, you can use the file's short name to rename it.

i apologize for the long delay in following this up. GetShortPathName() doesn't work and fails a second requirement of a network file (seems to return NULL)
thanks for the suggestion.

I have used Winsock2 for my application to communicate with the device over
TCPIP socket.I get the following sequence of events .
1. The Application that runs the Client socket is alive.But after about 24
hrs. the network connectivity for the Machine is disabled.
2. On further investigation of the issue I found that in the Event viewer
the event has been noted as Event ID -2019 and the note alongside is
"The server was unable to allocate from the system nonpaged pool because the
pool was empty."
On further investigation of my code I find that the WSARECV() call that I make to receive the data bytes from the server socket is causing the memory leak of non paged bytes.
Do help out with this issue.

CComboboxEx::FindString is not supported.
Do I have to do the search manually?
|
|
|
|

Sorry for my first reply, didn't scroll down far enough in docs. I guess you'll have to either brute force it or maintain a searchable array separate from the combobox itself. Since it's ownerdrawn, don't you have to maintain the array yourself anyway? If not, why not try it that way?
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

so, I think I should use GetItem, and compare with each cbi.pszText.
|
|
|
|

Call GetComboBoxCtrl() to get the CComboBox object and then call FindString() on that.

Does calling FindStringExact() work on that combo box?

I also doesn't work.
I've done it by comparing item by item.
Thank you all the same.

It should. ComboBoxEx controls definitely forward the CB_FINDSTRINGEXACT message to their child ComboBox control (see here[^])
