- MFC >> Tooltip causes an ASSERT() in a child dialog boxHello experts,
I already posted about my problem a couple of days ago, but it's not
solved yet and I have some more details about it.
Using MS VC 6.0 and Vista.
I create a CTabCtrl control in a dialog box. For each tab, a child
dialog box contains a bunch of controls (CEdit, CComboBox...). I can
display tooltips for each control, no problem.
The problem is that when the cursor (I mean the mouse) leaves a
control, if it enters the tooltip area, I get an ASSERT() warning:
In WinCore.cpp
void CWnd::AssertValid() const
{
...
// should be a normal window
ASSERT(::IsWindow(m_hWnd));
...
}
This occurs only when the dialog boxes displayed in the tabs are CHILD
dialog boxes. If I choose "Overlapped" or "Popup", it works (but I
need a child dialog box).
What should I do to avoid this problem?
TXS

- Visual Basic [VB] >> Using VB 6.0 Interface in vb.net causes a problemHi,
I have an interface in vb 6.0. It has a property set member, which takes a
parameter by reference. When I try to implement this interface in my vb.net
project it gives me an error saying that "cannot implement property set
because there is no matching property on interface". I think .NET does not
allow parameter to be passed ByRef in property statements.
here is my property set statement in vb 6.0 interface called IName
Property Set Name(ByRef objName as object)
End Property
VB.NET code looks like this
Public WriteOnly Property Name() as System.IntPtr implements IName.Name
Set (ByVal value as System.IntPtr)
end set
End Property
There is an underline below IName.Name. When I put my mouse over it then it
says "Cannot implement IName.Name because there is no matching property on
Interface IName". I tried changing the System.IntPtr to System.Object but it
gives the same result. I cannot change vb 6.0 interface to accept parameter
ByVal instead of ByRef because then, I have to change all other existing
components that already are implementing this interface.
Your help is appreciated.
Thanks

- MFC >> Message which is called everytime a CFormView is createdHallo,
I have a program with a CSplitterWnd which divides 2 CFormViews.
See link: http://wwwstud.fh-zwickau.de/~pafe/geb/1.jpg
When I start the program the ListBox (CListView) on the right side
gets filled in the method OnInitialUpdate().
When I navigate through the tree then the views on the right side are
replaced.
When I come back to the element, that displays the form with the
List-Box, my ListBox is not filled with the data I provide in
OnInitialUpdate.
See link: http://wwwstud.fh-zwickau.de/~pafe/geb/2.jpg
Now my question is:
Where do I have to put the code (what message do I have to catch) to
get the ListBox filled everytime I select the corresponding
tree-element.
Thx 4 ur help

- MFC >> Multithreading, Converting a Byte Array to a Hex String, Simultaneously..So.. my problema: I'm reading in a massive amount of data into a BYTE
array buffer (size 64096 bytes, and about 1MB every 5 seconds) and
writing to a file. I want to grab the info, translate it into hex, and
spit it back out on the screen to display what I am receiving. So far
I have a thread doing the receiving and writing to file, and another
thread which is supposed to be translating and spitting out to a
multiline edit box.
This is probably not a good way to do it, and I was wondering if anyone
knew a better way?

- VB Scripts >> Variables from one script to anotherHi...
I posted this before, but probably didn't explain my self well...
I need to have a script that declares and sets a value for some vb
variables, and want to have the value in these variables available in other
script...
Here is what I do :
I have a master script that calls other scripts...
1st script called from master script, it declares and sets values for some
variables ...
ex : Public appver1
appver1 = "V9_4_2"
2nd script called from master script would use the variables set in 1st
script to do execute actions with it...
ex : WshEnv("Var1") = appver1
How can this be done ...
The value is "appver1" is not necessary outside of the vb environment...
Reason is that 1st script will be modified by a lot of people, but don't
want them to modify other script...
Thanks very much !!!

- Visual Studio C++ >> Seeking opinions of best practice on splitter windowsHello
When having a splitter window, i.e. a window that is about 5 pixels wide and
goes between the left-hand treeview and the right hand control, be it mdi
client window or listview or whatever, is it generally preferred practice to
have the left and right windows resize as the user is dragging the splitter
window, or to wait until the splitter window is dropped.
I notice that most Microsoft applications (e.g. Windows Explorer, Outlook
Express) go for the former, however it seems Visual Studio .NET adopts the
latter strategy.
I've coded my application so that it works like Visual Studio .NET. However
I can't make the splitter window adopt that transparent-gray crosshatch
pattern when it is being dragged, anybody know off-hand what the background
needs setting to to make it like that?
And also, which is the 'best-practice' method, or doesn't it generally
matter either way?

Only the source files are required (cpp). they'll include the headers
anyway.

You generally don't need to do anything, because the default is to include all the files
in your project.

- Visual Basic [VB] >> xlSheet.get_range not thereI'm trying to use the get_range method on an Excel sheet, but when I type

Dim xlSheet As Excel.Worksheet = CType(workbook.ActiveSheet, Excel.Worksheet)
xlSheet.get_Range(.......) 'I CAN'T DO THIS

According to documentation it should be available for VB as well. I don't
know what I'm doing wrong.

- Visual Studio C++ >> good code to return const reference to function local object?Hello everyone,
1. Returning non-const reference to function local object is not correct.
But is it correct to return const reference to function local object?
2. If in (1), it is correct to return const reference to function local
object, the process is a new temporary object is created (based on the
function local object) and the const reference is binded to the temporary
object, and the life time of the temporary object is extended to the life
time of const reference?
Or no need to create such a temporary object, just let the const reference
binded to the function local object itself?
thanks in advance,
George

- Visual Basic >> Storing/Loading queriesHi all,
In my VB application, I have some listviews and some
comboboxes. The code forms a query based on the values
selected in these components and queries a database.
Now, I want to give the user the facility of saving and
loading queries, that is, when a user selects a stored
query the corresponding values should be shown selected in
the list boxes and comboboxes.
Could anyone give me an idea about how to go about it, as
to how should I store these queries (in files or in the
databse itself) and how to populate the components based
on these queries, when they are loaded? Or where could I
find a sample of code doing similar stuff.

- Visual Basic [VB] >> binarywriter.write loop is causing 100% cpuHi all!
I have some files that are basically a TIF with an ASCII header.
I wrote an app that reads in the file, pulls some values from the
header and writes out everything after the header as a new file.
I'm using binaryreader and binarywriter.
Everything functions fine, but the following loop causes 100% CPU
usage and I can't figure out how to get around this.
Here is a code sample that lists the declarations and the loop that's
causing the high CPU usage:
----------------------
Dim fsIn As FileStream = New FileStream(filename,
FileMode.OpenOrCreate)
Dim fsOut As FileStream = New FileStream(fsIn.Name & ".tif",
FileMode.Create)
Dim binWriter As BinaryWriter
Dim binReader As BinaryReader = New BinaryReader(fsIn)
binWriter = New BinaryWriter(fsOut)
Do While binReader.BaseStream.Position <
binReader.BaseStream.Length
binWriter.Write(binReader.ReadByte)
Loop
binWriter.Flush()
binWriter.Close()
binReader.Close()
binReader = Nothing
fsIn.Close()
fsIn = Nothing
fsOut.Close()
fsOut = Nothing
----------------------
Obviously I left some stuff out, but that's the part that's using the
CPU.
The binReader.BaseStream.Position picks up where the loop to find the
end of the header left off.
If anyone has any suggestions or tips as to what's going on and / or
how I can get around it I'd really appreciate it!
Thanks!

- VB Scripts >> getting remote time from vbscriptHi all.
I would like to get the time on a remote Windows host from vbscript.
I would prefer, if possible, to avoid using the NET TIME command.
I tried the LocalDateTime method provided by WMI, but that requires
administrative rights on the remote host, which is not an option for
me.
Does anyone know another way to retrieve the time remotely without
running another executable like net.exe?
Thanks,
John
