Hi there,
I am trying to save an Image from a database to a file but it only save the following to the file
"System.Byte[]".
fileWriter.Write(dsExportDataTypes.Tables[0].Rows[i]["ATTACHMENT"]);
fileWriter is an object of StreamWriter Class.

You're using the wrong class. StreamWriter is used for writing character data to streams. To save an image to a file, you need to use a class that will handle a binary stream of data. FileStream[^] is the most appropriate class to use. Your code would look like:
myFileStream.Write((byte[])dsExportDataTypes.Tables[0].Rows[i]["ATTACHMENT"]);

Hai All,
How can we open only one instance of a form at a time from a MDIparent form in C#.net
Thanks & Regards
|
|
|
|
|
this condition on Form1 would ensure that there's only one copy in the existence
if(obj == null || obj.IsDisposed)
{
obj = new Form2();
obj.Show();
}

You can do that by having a "manager" class that manage the child form.
1. Caller call a method in the manager, given the type of the form that you want to open.
2. Manager check MdiChildren of that type, if it finds it, return the form object back to caller.
3. If manager not able to find it, then create a new instance via reflection, then return back to caller.
4. Caller receive the form, do necessary action on the form (pass object, show, etc)
You can mix it up a bit by having some form can only be opened as 1 instance, while other form can be opened multiple time, by adding customattribute to the form class or adding an "AllowMultiple" via subclassing Form.
This is by no means the only way.

Any idea on mouseover outside the form?
eg:the form is not on focus and when i mouseover a text from another program an action will trigger.
|
|
|
|
|
i think you can not do that because you will be out of the scope of the event,
but try to google for background processes something like that to capture the mouse.
|

|

thanks but, may i know how is actually API SPY 2.7 work? when we use mouse to mouseover others windows form object, it will show the object handle, text, class and so on. it zit related to as what you hav mentioned background processes?

This isn't how the site works. People don't do your work for free.
What research have you undertaken to solve your problem? What code have you already tried to write?

static public void ToFile<t>(T[] vec, string name) where T : IEnumerable<t>
{
using (StreamWriter sw = new StreamWriter(name))
{
foreach (T v in vec)
sw.WriteLine("{0}", v);
}
}
Now to call that function with:
double[] vec = { ...some numbers ... };
ToFile.(vec, "filename.txt"); <---- error double[] sould be IEnumerable

You can't do that. You've constrained T to be enumerable, but T in your example is double and not an array of doubles.
