Hi,
I am creating a deployment project. Everything works well except the uninstall of the previous version. if I look in the Programs and Features window in Windows 7 the new version is updated in the version column, but the application still picks up the old version. When I run the msi again it asks for repair or uninstall. I uninstall, run it again, install and then it works.
Can anyone maybe help.
Thank you

if your app is a WinForms app and all of your code is running on the main thread, then Thread.Sleep(1000) will stall the GUI, which is not really acceptable; you should either use a timer to create a period of inactivity (a Windows.Forms.Timer keeps you on that main thread); or better yet, delegate the slow operations to another thread, have a look at BackgroundWorker.

Dear friends,
Small clarification.
Can some one tell me which one will be faster?
int a =100000;
string b = a.tostring();
string c = convert.tostring(a);
string d =""+a;

I think in release mode B and C have the same result. But for the purpose a.ToString() is the best one.
The D case is a coding horror for me.

Short answer: test it
I took a little look with the Reflector and I'm willing to hazard a guess: the first one. Because: the first one just calls Number.Format(something) which is an extern function, the second one calls int.ToString(some stuff) so basically it just adds a method call (which could be inlined by the JIT engine) and the last one also does some string appending, to which JIT magic may also happen, it might have an "if (first.Length == 0) return Second" and then the optimizer in the JIT compiler might decide that since the string is a constant, its Length is also constant, and then it might optimize that test away and skip the string appending completely.
That is very optimistic.
So, still test it..
Who knows, maybe it's even possible to write a faster IntToString method? I would look into it. Especially if a lot is known about the input (probability distribution etc). I wouldn't count on it, but you don't know until you try..

I don't know exactly. Test it!
However if you use a lot of int to string and then something like "string total = a+b+c+.... "
where a,b,c are strings obtained from ints than StringBuilder is the fastest and less
memory hungry.

Sounds like you're looking for an "Explorer Band"[^]

Google for "Windows 7 Taskbar .NET Integration" and you'll find an SDK you can use that might supply what you need.

You need to use the data adapters delete command to delete a row

In the user interface designer you can change the banner bitmap property to your own image.

hi,
Can I change the buttons labels from the setup ?
I mean: a button label "NEXT" to this "->", or a button label "CANCEL" to "EXIT SETUP"

Not in the Visual Studio designer, though I believe you can control that if you use WIX[^] or some other installer designer to create your installer package.

It's not easy, but you can add custom dialogs to Visual Studio setups: link.

Thanks,
I found that, however there is another issue, the size of the logo.
I made it 500px/70px, bud still it takes all the space on the welcome text section. I even made it smaller then 500/70 px, it still does not fit into the wizard

Hello, I have a routine that loops through all the controls on my form.
The purpose is to set the Edit Mode or Read Only mode.
To find textboxes and buttons inside a TabPage or GroupBox the routine runs recursive.
To convert a Windows.Forms.Control in to a Texbox I validate and use ..
if (c is TextBox)
{
ToggleTextBox((c as TextBox), flgEditMode);
}
So Far So Good.
If I do the same for a ToolStripButton I get the message:
Cannot convert type 'System.Windows.Forms.Control' to 'System.Windows.Forms.ToolStripButton'
Please can you help me with a work around?
Kind regards Arjen

Hello,
The ToolStripButton class doesn't Inherit from Control.
Inheritance Hierarchy:
System.Object
System.MarshalByRefObject
System.ComponentModel.Component
System.Windows.Forms.ToolStripItem
System.Windows.Forms.ToolStripButton
So you have to look for the ToolStrip class (which inherits from Control) an than iterate over the Items property.
Like this:
foreach (Control c in this.Controls)
{
if (c is ToolStrip)
{
ToolStrip ts = c as ToolStrip;
foreach (ToolStripItem tsi in ts.Items)
{
ToolStripButton tsb = tsi as ToolStripButton;
if(tsb != null)
{
...
}
}
}
}
Hope it helps!
All the best,
Martin
