Dynamicly putting checkboxes on a form HELP

Hi,

I'm making a windows form that dynamicly puts checkboxes in different FlowLayoutPanels. My problem is that when i dont turn on the AutoSize of a checkbox the text of CheckBox is wrapped. But when i turn on the AutoSize the loading of the form takes to long (about 5 seconds). Does someone knows if there is another way to auto size the text of a checkbox?

this is my code that puts the checkboxes on my form.
i have a array that contains the a string array that looks like this:
options[0] = Checbox nr
options[1] = Checkbox text
options[2] = the group index ther are 4 different groups

for(int i=0;i

DateTimePicker

What's wrong with the following line?
dtp_dob.Value = new DateTime(Convert.ToInt32(rrndata.Dob_Year), dtp_dob.Value.Month, dtp_dob.Value.Day);

If I show the datetimepicker value into a MessageBox it gives the correct date, but in the datetimepicker control today's date is shown Confused | :confused:

(I've also tried the Refresh method after setting the value)

This line works fine:
txtbox_dob.Text = rrndata.Dob_Day + "/" + dtp_dob.Value.Month + "/" + rrndata.Dob_Year;

tnx...

Coulda, woulda, shoulda doesn't matter if you don't.

That constructor of DateTime expects 3 integers - year, month & day.

You are only converting the first to an integer!

Look closely Smile | :)

. I take the month and day from the datetimepicker itself. I only change the year.
Secondly, the value of the datetimepicker is set correct, but shown wrongly.

Besides, if I would send a string to the constructor like that I would get an exception.

Maybe try giving a bit more info, especially what the value of rrndata.Dob_Year contains.

listen, I appreciate your help, but don't blame me if you didn't read the post correctly.

I clearly said in my original post that the value of the datetimepicker is set correctly, but in the GUI the datetimepicker shows today's date. I never overwrite the value later on either.

If you thought my post wasn't clear, my apologies. I thought it was clear and in any case don't loose your temper about such a thing, it isn't worth it Smile | :)

Im not mad about anything, but a quick "thanks for trying to help" would have sufficed.

I have nothing more to add, good luck solving your problem.

Thanks for trying to help, and I do mean it.

On second note: I just reread my second post and idd I could have been more friendly, I didn't mean to sound negative. You're reaction was overexagerated however.

Anyway, from my side no hard feelings and maybe another post will be more friendly towards one another.

hi V!

just want to ask an example value of the DateTimePicker and the Today's date?

i just asked because maybe, the format of your datetimepicker and Today's date is different...
You can set the datetimepicker format but the today's date format gets it on your regional settings.
try to look at this[^] if that's your problem

hope that helps! Smile | :)

hey tnx!
I was looking in that direction, because I noticed idd the format was different.
The second strange thing I saw was the following:

When I press my button, my value gets set, but today's date stays shown
When I than manually choose another date and than press the button, it works! Confused | :confused:

[EDIT]Damn, the solution that microsoft proposes will not work. The user is not allowed to change regional settings, but multilanguage support is still required Dead | X|

. I'm now searching for the short version (=property of dtp) or a masked textbox.[/EDIT]

i tried to test it but it works fine with me... perhaps i just misunderstood what you're trying to say?

actually, this was also my problem before so what i did to solve this was to create a custom control like the datetimepicker but not inheriting to it.

this[^] gave me an idea to create that control. Smile | :)

hope this also helps you! Smile | :)

It gives me some ideas tnx a lot... (although the links don't work anymore, but it gives me a search direction Wink | ;)

)

(And yes, the behaviour of my datetimepicker seems very, very ackward to me too. I've just set the initial Value in the properties (before compiling) to 1/1/1829. Yet at runtime, today's date is shown Confused | :confused:

.

I think I'm going to create some custom thing instead Smile | :)

GetForegroundWindow() not working as expected

hi all,

i am trying to get the active window asw a bitmap, an earlier post directed me to the GetForegroundWindow() function in user32.dll

this however (with the code below) is returning both my desktops as the bitmap not the active window.

can any please help?

internal static Bitmap GetForegroundWindowBitmap()
{
  IntPtr handle = GetForegroundWindow();

  //Get a device context from the desktop window
  IntPtr windowDC = GetWindowDC(handle);

  Bitmap windowImage = GetBitmap(windowDC);

  ReleaseDC(windowDC);

  return windowImage;
}


internal static Bitmap GetBitmap(IntPtr imagePtr)
{
  //Get a GDI handle to the image
  IntPtr hwnd = GetCurrentObject(imagePtr, 7);

  Bitmap desktopImage = Image.FromHbitmap(hwnd);

  return desktopImage;
}

the above code (GetBitmap) works fine to get 'a' desktop or all desktops if i pass in GetDC(GetDesktopWindow())

kind regards,
g00fy

Hello

first set your forms KeyPreview property to "true",
then on controls KeyPress event do your job like below code :

<br />
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)<br />
{<br />
  if (e.KeyChar == Keys.Enter)<br />
  {<br />
   ....<br />
  }<br />
}<br />

if this can not help you mail me please.
Bye Bye. Smile | :)

hi AnhTin! Smile | :)

so what you mean is when the user PRESS Control + Enter? Smile | :)

if your subclassing a control just override the OnKeyDown event

protected override void OnKeyDown(KeyEventArgs e)
{
   if (e.KeyData == (Keys.Control | Keys.Enter))
   {
     //do something here
   }
}

or if your just using the control... attach an event handler on the KeyDown event then do the same condition that i added in the onkeydown event.

hope that helps! Smile | :)
