Yes.
In the Main() method of your application you'll see a line like this:
Application.Run(new SomeFormClass()); Remove that line and the GUI won't get started.

 I should 've thought of that one; although in this case the other solution better fits my needs.
tnx!

I'm curious as to why you only want a GUI in debug mode. It sounds like you are using this as some sort of testing harness. If so, would it not be better to create some repeatable unit tests instead?

No, We have a core application here at work, where you can plug in other programs. The developers before me, just added an exe for each little Change request, creating a directory full of exe's. If you click one, without the core application started, it will start the application empty (that's not the idea)
I'm making some start to clean up things. One is that I only use 1 exe that will load the appropriate program (In time to be recompiled as dll's, I hope). If no arguments are passed to the exe the GUI will show with an explanation, but if the arguments passed are correct, the user just sees the little program executed, nothing else.
It was the cleanest solution I could think off for the moment  .

this worked for me in the OnLoad of a form;
this.ShowInTaskbar = false;<br />
this.Opacity = 0;

thanks I can use this one...

please send me a code in c# that allows some IDE tools to click and drag. e.g. textbox,listbox,combobox...etc...
thanks....

There's three events you need to handle to do this. It's called drag and drop, if you use that terminology, I'm sure google has the details.

hey howzit.
I am looking for a component that can extract information about fields in a PDF. e.g. their height, width, location etc.
PDF fields are used in electronic forms and are becoming quite popular.
I am looking for a component which is of reasonable price or freeware.

Hi,
I have a ListView control holding more than 3000 items (which means sorting can take a while). Therefore, I want to display a message saying "Sorting list" while the list is being sorted. The problem is I don't know how to tell when the sorting process has completed.
Any suggestions?
|

|

You might be able to create a thread to sort the items and once that thread has finished then you can say that sorting has finished. You may run into a few problems because I think that using multiple threads to update UIs is messy, your best bet might be to disable the ListView first thus ensuring that the user can't change anything inside it.

You can show the "Sorting List..." message before performing the sort, and then hide the message after the sort operation completes by doing something like this:
private void btnSortAsc_Click(object sender, System.EventArgs e)
{
this.statusBar1.Text = "Sorting List...";
this.listView1.Sorting = SortOrder.Ascending;
this.statusBar1.Text = "";
}
private void btnSortDesc_Click(object sender, System.EventArgs e)
{
this.statusBar1.Text = "Sorting List...";
this.listView1.Sorting = SortOrder.Descending;
this.statusBar1.Text = "";
}

Hi all i have a small problem
I am creating a new blank bitmap in a program, then using the lock bitmap i edit pixels. the Purpose iss to build a spectograph.
Now my problem is that when i create the bitmap
Bitmap pane = new Bitmap(800, 800);
then edit it using pointers the image remains blank
the only work around i could find is initialiazing the bitmap with setpixels one by one.
This is obviously very slow and ive been trying to find a faster way :/
any suggetions ??

If you posted some code, we could perhaps suggest where it was broken. Obviously, the answer is to lock bits and edit the pixels, so you're doing something wrong. My image processing articles have lots of examples on how to do this, they are on this site, just search for graus and you'll find them

Sure
i Create the bitmap here
Bitmap pane = new Bitmap(800, 800);
then i had to init the bitmap with a colour to get it working
<br />
for (int i = 0; i < pane.Height; i++)<br />
{<br />
for (int j = 0; j < pane.Width; j++)<br />
{<br />
pane.SetPixel(j, i, Color.Black); <br />
<br />
}<br />
<br />
}
basically i have to get rid of the code above
then i use unsafe mode to set colours to individual pixels
public Bitmap backup(Bitmap pane)<br />
{ <br />
BitmapData panedata = pane.LockBits(new Rectangle(0, 0, pane.Width, pane.Height),<br />
ImageLockMode.ReadWrite, pane.PixelFormat);<br />
<br />
int stride = panedata.Stride;
IntPtr Scan0 = panedata.Scan0;<br />
<br />
unsafe<br />
{ <br />
byte* p = (byte*)(void*)Scan0; <br />
<br />
int nOffset = stride - pane.Height *3 ;<br />
int nWidth = pane.Width * 3;<br />
<br />
for (int y = 0; y < pane.Height; ++y)<br />
{<br />
for (int x = 0; x < pane.Width; ++x)<br />
{ <br />
*(p + 0) = (byte)255;<br />
*(p + 1) = (byte)0;<br />
*(p + 2) = (byte)0;<br />
p += 4;<br />
} <br />
}<br />
}<br />
pane.UnlockBits(panedata);<br />
return pane; <br />
}
like that it works but its takes ages to start

Is there any particular reason you are using pointers to do this? It could be accomplished whithout them. You could tie your bitmap to a graphics object...
Graphics g=Graphics.FromImage(myBmp);
...
then you could fill the image (much faster than indexing)
g.Clear(Color.Black);
Next, I take it you are setting the RGB value of each pixel in your for loop, but you are setting them all to Red as it looks, so why not just use....
g.Clear(Color.Red);
This will work very fast. If this isnt the solution you are needing, let me know,

i pasted only part of the code, the g.clear to fill the bitmap worked nicely just what i needed
and basically im trying to build a spectograph so not every pixel is being drawn and everypixel i draw has a different weight thats why im going tthrough it pixel by pixel.
the program is still in the early stages though thats why it may look a bit raw.
Thanks a lot for your help !

I think you are not seeing any changes because you don't set the alpha value and when it is left to 0 you won't see anything (everything is transparent). Adjust the contents of your inner loop:
*(p + 0) = (byte)255;
*(p + 1) = (byte)0;
*(p + 2) = (byte)0;
*(p + 3) = (byte)255;
p += 4;

erm yes that was it ! forgot about the alpha component :/ silly me 
|
|
|
|
|
Having read the thread, I can't believe you need to set alpha. I've never, ever had to set the fourth value, and it's not actually used for alpha by windows, unless the Bitmap object uses it.
int nOffset = stride - pane.Height *3 ;
This is wrong, you mean pane.Width. However, as you're using a 32 bit image, you don't need an offset, anyhow.

Is it possible to set ip address and computer name remotely or through MAC address?
lmyo
|
|

|

Yes, if you write a DHCP server which can assign IP addresses based on MAC addresses.
dhcpd on Linux can do this.

Well, you're looking for a POP component for reading Mail. Here's one I found on Code Project.
