Thanks Guffa,
I think your reply makes senses. Int only has max and min value, no infinite value, but float has, right?

Hi
iam in windows application using c#.
my database is "FireBird Database".
Database path is :
string dsRelativePath = "database\\absolutemedia.fdb";
string dsAbsolutePath = Path.GetFullPath(dsRelativePath);
string ConnectionString = "ServerType=1;User=SYSDBA;Password=masterkey;Database=" +dsAbsolutePath;
//Code for upload image
OpenFileDialog opn = new OpenFileDialog();
opn.Filter = "JPEG|*.jpg|GIF|*.gif";
opn.ShowDialog();
if (opn.FileName.Length > 0)
{
this.IMG = Image.FromFile(opn.FileName);
browsetext.Text = opn.FileName;
this.resizeHeight = 240;
this.resizeWidth = 320;
IMG = this.resizeImage(IMG, new Size(resizeWidth, resizeHeight));
imagebox.Image = IMG;
}
This path is working fine upto now..
but in my application, i have an option to upload images from local drives..iam browisng an image thru "OpenFileDialog".. after selecting an image .when iam going to save ,

Use a Timer.
But remember the timer elapsed events get triggered on a different thread, so you'll need to do an Invoke call if you want to work with any GUI objects.

I was wondering...
There's a SendKeys function to send keys...
What about a SendClick(x, y); function?
Does one exist, that I just don't know about?
(I'm trying to avoid messy DllImports  )
|
|
|
|
|
Not sure if it's exactly what you want, but my guess is you wanna click a particular button. Is myButton.PerformClick(); what you're looking for?

Oh Cool!
Was more looking for MouseClick(x, y); for automation purposes, but WOW! That's useful!!!
Just wondering why it works in normal windows forms, but not with ASP.NET Buttons :p

are you looking on form.show()?
|
|
|
|
|
Exually what i have are 6 forms,
and 6 buttons
what i'm looking for is :
button 1 > form 2 + backbutton
button 2 > form 3 + backbutton
button 3 > form 4 + backbutton
button 4 > form 5 + backbutton
button 5 > form 6 + backbutton
button 6 > form 7 + backbutton
button 1 when pressed opens form 2 ect.
that works with form.hide(); ? and form.show(); ?
|
|
|
|
|
I tryed to use
Form.ActiveForm.Hide();
Form2.ActiveForm.Show();
but that trows System.NullReferenceException was unhandled
|
|
|
|
|
You need to create an instance of the form you wish to show/hide, that's the exception you're seeing.

hope this help you

Alternatively you could create user controls, one for each form you need, and populate them with the components that you need for each form and then use just one form in which you show one of the user controls and then switch it for another. This way the user controls works like different views in the same form.

For a project which I soon have to be involved in, we are looking to implement a graphic intensive application, but balk at using either MDX 1.1 or XNA to access the DirectX libraries. However, the development platform has to be C#. Is there any way to get to the DirectX libraries (and how on earth do use them) directly, through unmanaged calls?

You could do, but then you'd only be doing what MDX does anyway.
Unless you are an expert at unmanged DirectX don't use it; it'll take you longer to write, be less managable, and won't really be much quicker. From personal experience it took me getting on for 100 lines of code to get keyboard input in unmanaged DirectX and 3 in managed.
On a final note, the extra cost of development will more than offset the cost of a new graphics card for the whole company if it's of any real complexity.

How to get the user Telephone Inputs into our C# application...??
Regards

Look into Interactive Voice Response applictions and maybe the Microsoft Speech SDK. They have ways to detect DTMF signals as input. You should also look into learning VXML as most of the IVR systems use that for the call flow.
