Re: how to close the form after specific time??

5-Aug-04 22:55

Create a Timer on the form and set the interval to 10 seconds. Create an event handler that will close the form when the timer's event fires.

"If a man empties his purse into his head, no man can take it away from him, for an investment in knowledge pays the best interest." -- Joseph E. O'Donnell

Can't manage to P/Invoke that Win32 API in .NET? Why not do interop the wiki way!

Just don't forget to enable the timer, it defaults to disabled.
I spent a while trying to figure out why my timer event's were not firing the first time i used one!
DOH!! Laugh | :laugh:

Maybe someone else is. Maybe someone with a similar problem read your query this morning and thought "That sounds like the problem I'm having. I'll have a look again later and see if anyone else replied." So, now that person is disappointed because you know the answer but didn't tell anyone.

Good etiquette would dictate that you should tell the rest of us the answer to help educate us all - even those who were not seeking the answer to your question may find something useful after all.

Now, what's is the answer to the question, o' great wise one? Big Grin | :-D

That's funny - thinking that someone would actually try searching this forum before posting a question for the "umpteenth" time. Smile | :)

That is very commendable, however that was not the reason for my post. The reason for my post was that you announced to the world that you knew the answer, but you did not tell the world the answer. You kept the answer to yourself. CodeProject is for sharing information.

It is good manners, if you find the answer to the question you asked, to tell everyone that (1) you found it [which you did] and (2) what the answer is [which you did not].

So, I repeat: What is the answer to your original question?

Who is going to draw ?

Tabcontrol have a properties called DrawMode. This will set or get the value that whether user or system will paint the caption.By default it is normal. Means system(OS) will paint the caption for you. If you(parent form) want to draw the caption you have to set the value of the property to OwnerDrawFixed.

You can mention DrawMode on design time or runtime like below mentioned code.

this.tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed;

Now you mention who is going to draw the caption.

Next thing is how is going draw ?

Tab control have an event called DrawItem event which will occure when ever an area need to be painted.

eg:

this.tabControl1.DrawItem += new DrawItemEventHandler(this.tabControl1_DrawItem);

private void tabControl1_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
{

Font f;
Brush backBrush;
Brush foreBrush;

if(e.Index == this.tabControl1.SelectedIndex)
{
f = new Font(e.Font, FontStyle.Bold | FontStyle.Bold);
backBrush = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.Blue, Color.Gold, System.Drawing.Drawing2D.LinearGradientMode.Vertical);

foreBrush = Brushes.White;
}

else
{
f = e.Font;
backBrush = new SolidBrush(e.BackColor);
foreBrush = new SolidBrush(e.ForeColor);
}

string tabName = this.tabControl1.TabPages[e.Index].Text;
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Center;
e.Graphics.FillRectangle(backBrush, e.Bounds);
Rectangle r = e.Bounds;
r = new Rectangle(r.X, r.Y + 3, r.Width, r.Height - 3);
e.Graphics.DrawString(tabName, f, foreBrush, r, sf);
sf.Dispose();
if(e.Index == this.tabControl1.SelectedIndex)
{
f.Dispose();
backBrush.Dispose();
}
else
{
backBrush.Dispose();
foreBrush.Dispose();
}
}
}

Hi,

I have a c# console app that periodically look at one directory to see if any new folders have been uploaded there. If it finds a new folder it should move this folder to a different folder. This works fine my problem is that it moves this folder with the old permissions. Is there any way that I can change the owner of this folder to be set to its new parent folder? I have had a look at activeDs but I just can't seem to delete the existing permissions I can however add new permissions.

Any help would be greatly appreciated.

Thanks in advance.

See http://weblogs.asp.net/cumpsd/archive/2004/02/08/69403.aspx[^] and follow the link to the GotDotNet sample, which is written by Microsoft and will be included (in some form) in the upcoming .NET 2.0 release.

Also keep in mind that you must have (or rather, your application) the right permissions to make changes you requested, otherwise what would be the point of file security?

Reflection Question

Hello everyone.

I've been trying to find a way of figuring out how to know which method called another method.

For now I'm using the ~~MethodInfo~~ MethodBase Object and passing it as a parameter to the called method but is there a better way of doing it? I know that you can find out who the calling assembly is, but how do I find out the name of the method that made the call?

Thanks for any help.

Look at my post regarding exactly how to do this, a few posts down (i think yesterday or the day before), on how to use StackTrace. From there u can get the MethodBase just as you want it, but be warned, it will likely be much slower than passing MethodBase.Current. Anyways, I dont find anything wrong with your approach as long as you keep those ugly ones private! Poke tongue | ;-P

Thanks for your reply, I'll look into your suggestion.

I don't see anything wrong with it either other than I'm lazy and don't want to have to create the methodbase object from each of the methods that calls that particular method, I'd rather have the called method figure it out.

Again, thanks for your help.

Statically linking dependency assemblies

Hi Friends

I have a console application that produce assembly in .EXE. This app has some dependency assemblies which it reference in the project.

Now i want to give my client only the .EXE file. So i want to statically link the dependency assemblies in this .EXE .

The Assembly Linker tool(al.exe) only links the modules or the resource files.

Any pointer and idea is most welcome.

Thanx a lot

Static linking is not supported by the .NET framework. True, you can combined a few assemblies, but its purely a hack, not static linking in the true sense. .NET is designed around dynamic assemblies that are self-describing.

I am curious. Why? What is wrong with distributing a few assemblies? If this was really an important requirement why didn't you build it as one exe in the first place?

Hi you are right at your place.

But right now my concern is to link the dependent assembly into the main assembly file.

Hope any body would be having the idea for this
