Hi Christian,

I would love to get that ID3V2 class you spoke of! I always use V2, so V1 won't work for me. I don't plan on selling (or widely distributing) this application.

Thanks!!!

CEdit Box -- select all contents

JennyP5-Aug-02 6:05

Hello,

When clicking on a CEdit box, I would like the entire contents of the box to be selected (so that the user can simply overwrite existing text instead of manually backspacing over the existing contents). I have searched and didn't find anything on MSDN help. When a user tabs to the CEdit box, the entire contents are selected--the exact behavior I want for a user mouse-click. Any suggestions?

Thanks!

override OnSetFocus (handle EN_SETFOCUS) for your edit control, and then call m_myEdit.SetSel(0,-1);

Hi Chris,

I've done just that, and no dice. I verified that it gets called with TRACE but the edit box still puts the insert cursor where the mouse was when I clicked on it. Do I need to call more items from the function? Here's the function....

void CDiagGoalSched::OnSetfocusEditDue() <br />
{<br />
     // This doesn't seem to work...  I want a mouse click to select entire contents.<br />
     TRACE0("SET FOCUS...");<br />
     m_CtrlEditDue.SetSel(0, -1);<br />
}

Thanks!

try this:

::PostMessage(m_edit.m_hWnd, EM_SETSEL, 0, -1);

Bingo! Why does this work and not the first one? Is it the order of window messages in the queue? (I.e., the m_EditCtrl.SetSel() was before the Edit's translation from mouse position to cursor position?)

Thanks!

yep, i think you explained it. by posting the message (instead of Sending as SetSel does), you give Windows a chance to finish the Focus Change message (which probably ends with the edit control clearing the selection) before you change the selection manually.

Chat Server

Hi !!
I am designing a chat server these days. The server is designed in a manner to scale upto thousands of connections.

But i want one advice. The message from one client to another is protocol specific. Server decodes the message and find out information regarding target connection. Here lies the problem. What information i include in the message so that server easily find the target socket???

Infact whenever new connection established, i keep its pointer in std::vector data structure and send the position of that socket in vector to all other authorized buddies. But this is not a good approach. If one buddy disconnects, the position of others in vector is disturbed. So i want advice in this regard.

std::map with GUID as a key?

Hi,

I'm trying to use MSFlexGrid On ATL Composite Control but it's giving me error. If I use this control in MFC based application it works fine but crashes in ATL. Do U've any idea how to use an ActiveX control on ATL Composite Control?

Which kind of error? Can you see your flex grid window if you test with ActiveX Control Test
container?

I have:

_variant_t *tempkeyValue = new _variant_t[60];

that executes fine on WinXP but crashes on Win2K. Any ideas why? And how to get around it?

Thanks,

Somewhere earlier in your program you have trashed the memory and thus the allocation is failing.

Hello, the codegurus around the world.;)

I guess that you misunderstand how you get the vaule with VARIANT type.
Generally speaking, we have some helper function convering from VARIANT to
string.
Check DAO sample in MSDN to find the helper function.

Please, don't send me your email about your questions directly.
Have a nice day!

hi all, do you know how to get one cell of Excel file?
I need to format exiting excel file such as pagesetup, margins, and set the print area.
sometime, the file contains 300 pages but 50 pages are empty. So how can i get rid of those 50 empty pages programmatically?

thanks.

Tomasz Sowinski5-Aug-02 3:41

You'll probably have to use Automation. Check the COMEXCEL sample (comes with VC++).

yes.. i'm using automation.. I got everything i needed except for deleting those empty pages...
I don't want to print all the empty pagess while i print the file. Normally (not programmatically) I just have to select the area that i want to be printed, then go to next area which contains information, select it again and right click add to print area.. but how can i do the same action promatically???

Tomasz Sowinski5-Aug-02 4:46

Well, try to record the VBA macro which does the thing you want. Conversion to VC should be quite easy - it should give you a good start.

huuu... but there is no way (that i know of) to write the macro that delete or get those empty 50 pages out from the 300 pages.
Is it clear to you? I have exiting excel file. I open with excel.application. get its worksheets, then sheets, and then sheet. for every single sheet I format it like its font size, page margins, set landscape, set print quality 300 dpi.. and so on.. then I printpreview, in programmatical way. The problem is when you print preview, you will see page number 34 is empty, 55 is empty, 78 - 90 is emtpy, 276-280 is emtpy. nothing to be printed, it's blank page.

How can i get rid off those empty pages???? Please help me.

By deleting the rows? I can't give you any detailed info - it's been a while (about 3 years) since I've been working with automation.

Try to achieve your goal in VBA first. Start macro recording, select and delete row of cells - this should give you a way to remove empty spaces.
