When you expand which column? All the way to the right of what?
We can't see your screen, or read your mind. Please be more specific.
In general, the listctrl handles scrolling very well, so what you're describing is very strange. What customizations have you made to the listctrl?

The exception being the paint problems when using LVS_EX_GRIDLINES, with grid lines sporadically disappearing.

There is a well-known fix for this.

I haven't seen this problem at all on Win 7, so I hope Microsoft finally got around to fixing it.
The fix you found is basically what I have been doing on XP systems. If you use customdraw, there are a few other tricks you can use. For example, the function GetSubItemRect() is always incorrect for subitem 0; fixing this solves some problems.
I have also found that the cell rect is sometimes one pixel too tall. I'm not sure what the necessary conditions are for this to happen, but a fairly trivial fix is to reduce the drawing rect in the WM_CUSTOMDRAW handler.

Thanks for the info. Do you need to check the OS version before adjusting the drawing rectangles, or does your fix work on Win7 as is?
|
|
|
|

I don't check the OS version. I'm not sure what that would mean, since you can set the compatibility mode of an app to a different OS; haven't checked for this.

Hans,
It happens when I drag the resize bar on any columns. For example, if I expand the 12th column, it pushes the rest of the columns to the right of the view.
In window explorer, the horizontal scrollbar on the bottom would adjust dynamically so I can see the all the columns to the right of the 12th column.
In my list view, the scrollbar doesn't adjust at all, so column 13, 14, and 15 get pushed out of the list view.
I have these styles setup for the listctrl:
LVS_REPORT | LVS_SINGLESEL | LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES |LVS_EX_SUBITEMIMAGES
I hope I'm explaining a little bit more clear this time. Thank you very much for replying.

Without seeing your code, I would guess that you're not setting the columns correctly when you initialize the listctrl. In particular, look at the column widths you specify.
|
|
|
|

I probably did or didn't do something which caused the scrollbar to stop working in my listview.
I wrote the following workaround in OnHdnItemchanged and it sort of fixed the problem except that
if I push the last column all the way passes the right edge of my listview, the scrollbar thumb track
does not adjust or the view does not expand to include the last column.
int iTotalWidth=0;
for(int i=0; i < 16; i++)
{
int iWidth = GetListCtrl().GetColumnWidth(i);
iTotalWidth += iWidth;
}
GetListCtrl().SetScrollRange(SB_HORZ, 0, iTotalWidth,0);
Invalidate();
If anyone has any idea, please help!
Thanks!!

I have declared a variable
CADORecordset* m_Rpipe; in class
CPipeLineView
I call a method
bool DetectSeque(int pipeID) in class
CPipeLineView
In function
bool CPipeLineView::DetectSeque(int pipeID )
like follows
<br />
bool CPipeLineView::DetectSeque(int pipeID)<br />
{<br />
m_Rpipe=CPipeDAL::GetPipeByID(pipeID);
<br />
m_Rpipe->->MoveFirst();<br />
<br />
bool flag=false;<br />
<br />
<br />
<br />
<br />
while(!m_Rpipe->IsEOF()&&!m_Rpipe->IsBof())<br />
{<br />
<br />
if()
{<br />
.....<br />
}<br />
m_Rpipe->MoveNext();<br />
}<br />
return flag;<br />
}<br />
<br />,
as what is list above, errors accur while running at
m_Rpipe->MoveNext() .But when I put
m_Rpipe->MoveNext();
before
if sentence,it runs normally!
Please lend me a hand!
|

what errors do you get?
Additionally, I don't think you've pasted that code correctly - the second MoveNext() is out of the while loop and superfluous
How many rows are you expecting to fetch in this rowset?
|
|
|
|
|
I am sorry to make such a mistake.m_Rpipe->MoveNext() is in while loop
A dialog box pops up,which says "First-change exception in PipeLine.exe(KERNEL32.DLL):0xE06D7363:Mircosoft C++ Exception".
Thanks in advance.Do me a favor.

We need to know what exception you're getting ...
I would *guess* that the problem exists in your if(...) clause, and it seems to work when you put the MoveNext before it, because you're getting the second row of your rowset, which doesn't fulfill your if(...) test
Just guessing mind, there's not an awful lot to go on there 
|
|
|
|
|
I just want to scan all objects in recordset m_Rpipe while it fulfills certain condition.
There are no questions in if clause.
|

you need to run this under the debugger to find out what's going wrong
|
|
|
|
|
Ok,I'll debug carefully to find out the errors.Thank you again.

Process A launches process B with re-directed out, and err.
Process B must write to the console only - no re-direction (as the output will obviously be routed back to Process A).
I have tried a number of ways; including _cputs() etc. But I need a method where the output is rendered faithfully - where extended ASCII chars are written correctly. None of the 'console only' output functions seem to support this.
Any suggestions? Third party libraries I might look at?
Thanks in advance.

Hi Hans.
Thank you for the suggestion but all of the variations of printf, cout etc .. all write to an (re-directable) output stream. I need to write the console only.
|
|
|
|
|
You might try CreateFile() with device name "CON" and dwDesiredAccess = GENERIC_WRITE.
|
|
|
|
|
Thanks Hans ..
I am going to try that!
Cheers.

Hans.
Thanks a lot for the CreateFile() suggestion. It works perfectly .. I am delighted. You should create a short post about CONS only output. There is lots out there about re-direction etc .. but nothing that I could find about faithful rendering of console only output. Again .. cheers.
Best regards.
James.

Thanks for letting me know.
For my own curiosity, can you say why you want to disallow redirection?
|

Hi Hans.
I have been writing an application for a few years now .. www.tenfiftytwo.co.uk/pipelines
It's basically a multi-stream pipelines (textual manipulation) app that will allow you to chain together pipelines to transform text/data.
I am developing a TRACE option that allows interactive user input to inspect i/o records and in order to do this each called process must share the same console. So, console prompts must be just that - no redirection back to the calling process. They need to be console only. Only the called process output should be captured by re-directed streams.
Best regards.
James.
PS. Cannot believe that I did not think of CreateFile() .. thanks again.
