Hi ,
As anyone encountered an error message stating that the form that was specified as the MDI Parent is not an MDIContainer. I can understand that this would arise when the form has not had the IsMDiContainer property to true however i have set this property and the application was running fine until yesterday evening any ideas. i am about to unistall framework and VS2003 and reload.
Can anyone help?
Cheers

I use managed C++ and use Application::Exit() to terminate my program. The GUI was gone after call the function. However, the process is still in my Windows Task Manager. How can I kill the process when I exit the program?
My code starts at:
int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
System::Threading::Thread::CurrentThread->ApartmentState = System::Threading::ApartmentState::STA;
Application::Run(new MainForm());
return 0;
}
and end with:
MainForm::Close();
Application::ExitThread();
Application::Exit();
Anything missing here? Your help will be greatly appreciated.

your thread is still runnig probabliy because you didn't do a good cleaning (you leted some objects that couldn't be closed opened)
I sugest you close the program by simply by calling Application::Exit(); this closes the window opened for message loop end exits the application.
if you are not satisfied by this mthod you colud always abort a thread (cause an imediatly close and resource freeing process) like this (for the curent thread) System::Threading::Thread::CurrentThread->Abort();
I hope you understand...

Good day all…
I am interested in adding the fading color (similar to the Windows Media Player version 10) scheme to my Main Menu. Does anyone have an object type or maybe guide to a location where I can complete this solution?
Thanks in advance for your assistance.
Have a great coding day.
Regards,

I have the following code, but I cannot seem to get the changes in the dataset to be commited to the database. All I get is a 0 rowcount:
Private editQry As String = "select idc,nomiko,Eponymo,Onoma,Tel from Persons where idc=1"
Private adoCEDataAdapter As SqlCeDataAdapter
Private CustEditDataSet As DataSet
Private cb As SqlCeCommandBuilder
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub
Private Sub frmCustEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
adoCEDataAdapter = New SqlCeDataAdapter(editQry, frmConnect.adocon)
cb = New SqlCeCommandBuilder(adoCEDataAdapter)
CustEditDataSet = New DataSet
adoCEDataAdapter.Fill(CustEditDataSet)
txtSurname.DataBindings.Add(New Binding("Text", CustEditDataSet.Tables(0), "Eponymo"))
txtName.DataBindings.Add(New Binding("Text", CustEditDataSet.Tables(0), "Onoma"))
txtTel.DataBindings.Add(New Binding("Text", CustEditDataSet.Tables(0), "Tel"))
cbLegal.DataBindings.Add(New Binding("SelectedIndex", CustEditDataSet.Tables(0), "nomiko"))
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MsgBox(adoCEDataAdapter.Update(CustEditDataSet).ToString())
Me.Close()
End Sub
I have tried to create the Update query with:
adoCEDataAdapter.UpdateCommand=cb.GetUpdateCommand
and it returns a query, but again nothing happens on the adoCEDataAdapter.Update(CustEditDataSet)
Help....

Hi all,
I've created a new windows form application (C++) project,
and I can't see the form's events - not under the Properties window and not in the bar that is above my code editor. Do I have to add anything to support this?
thanks.

You can do many things to get .NET installed on the target machine. InstallShield has .NET built in and will create an installer or if you have Visual Shtudio 2003 then you can use the PluginInstaller[^] from Microsoft and then just create a setup project and .NET will be included for you.

I am using Visual Studio 2002 Framework 1.0. How do I use the installshield? Again this is my first deployment so any examples would be great.
Thanks

Installshield is a separate app that you would have to purchase. You would be in better shape to just use the deployment projects that are built into VS 2002.

How do I do that? I need to figure out how to check if the computer has framework 1.0 and if it doesn't install it.
It tells me that Dotnetfx.exe can be redistributed with your setup. How do you do this?
Thanks

Hi !
I've got an binary executable from Internet, which firstly checks if .Net is installed on the computer. If not , it executes dotnetfx.exe to install .NET. After installed .NET, it automatically launchs the deployment of your windows application.
This binary executable works with a configuration file. Here is the content of this file named settings.ini
[Bootstrap]
Msi=<DeployingApplication.msi>
FxInstallerPath=<D:\dotnetfx.exe>
where
<DeployingApplication.msi> is the path to your windows application installer .
<D:\dotNetFramework> , is the path to dotnetfx.exe
Then save the modifications.
But I don't know how to send you the binary file that automatically install .NET
Could you help me ?

Hi
Am I creating a new file called settings.ini or am I modifying an existing one?
What is the file called that automatically installs .Net? If you know where it is just send me an email and attach it to the email (timothy at myactv dot com). Or if you can remember the link from where you got it, you can send me that too.
Thanks

Here is a link to the .NET Downloads[^]. This link has all versions of .NET and the service packs too.

I have downloaded the framework 1.0 sp2 and installed it. How do I use it in my deployment project?
Is there something I am missing here?

Microsoft made is simple to add the framework to your setup programs for the VS 2003. I am not sure if the same thing works on 2002 or not. I am thinking that it would not. InstallShield was one of the simplest ways to put it in, but that is a separate purchase. The NSIS[^] installer has samples of getting the framework from Microsoft's website during the install. For 1.0 there was not a really good way that I know of to make sure that it was installed besides a 3rd party installer. That is one reason that I upgraded to VS 2003.

 I have a Form with a ListView and two buttons(Move_Up & Move_Down). I want to reoder the ListView by moving an item up or down by clicking either the button Up / button Down. I get the selected listView item's Index, then use Index + 1 or Index -1 to move the item up / down. The code of move up with Index-1 works. But the code of move down with Index+1 does not work. I don't know why, please help! Thanks! The code is as follows:
// this move up works (Index-1)
private void btnUp_Click(object sender, System.EventArgs e){
if(listView1.Items.Count != 0){
ListViewItem item = listView1.FocusedItem;
if(item != null){
int index = item.Index -1
ListViewItem insert = (ListViewItem) listView1.Items.Insert(index, insert);
listView1.Items.Remove(item);
}
}
}
// this move down does NOT work (Index +1)
private void btnDown_Click(object sender, System.EventArgs e){
if(listView1.Items.Count != 0){
ListViewItem item = listView1.FocusedItem;
if(item != null){
int index = item.Index + 1
ListViewItem insert = (ListViewItem) listView1.Items.Insert(index, insert);
listView1.Items.Remove(item);
}
}
}

It doesn't work becuase.... oh, i'll just show you
The list:
Item1="1"
Item2="2"
Item3="3"
OK?
now lets say you want to move the item at index 2 one step down, your
code does two things, add a new item, and removes the old one, right?
lest do these two steps-
Step 1 - add new item
Item1="1"
Item2="2"
Item3="2"
Item4="3"
Now if we remove item at index 2+1 (item3 now) what do you think will happen?
what you need to do is switchi between the item(index) and item (index+1)
the same thing will work with moving an item upwards - switch item(index) with item(index-1)
it will be a lot faster then using the insert/b> method, trust me

First, i know this isn't the best place to post this article but i felt this has something to do with the frameworks...
I have a really big application running on vb6, it will take months to port it to .net
in the meanwhile i need to use some GDI+ capabilities (and some threading).
I wrote some DLLs that will do the job for the big applications, but i don't know how to export them to VB6,
When i'm trying to add the reference to the DLL, it gives me an error message that it cannot use that kind of DLL.
I thought of using OCXs instead, but i don't seem to find a way to create an OCX in VB.Net (i know i can do in c++/# but i have tons of code already written in VB.net and i'm on a tight schedule)
Can anyone help me out?
