What is it that you want to save? Where do you get the data from? In what form?

thank you for your reply!
sorry! i'm just kidding! (where do i begin....<= "Love Story") Wink | ;)

I mean that:
-you can save anything from your floopy, usb, or other devices to current harddisk.
-but, you can't not save files which have extensions of files type look like
*.mp3, *.exe, *.bat...etc.

Of course! i'm using Windows
Thank you in advance! Rose | [Rose]

Do you mean copying files? What is keeping you from copying certain files, then?

In C# how do I put an updating time string into the statusbar? I am just starting to learn C# and though I know how to do this in MFC, I am not sure how to do it in C#. In serting a string I can do, but how do I get the time to update?

Smile | :)

Isn't there a special status bar panel for this?

Hi,

I have a dataset which fills my datagrid.

this.oracleDataAdapter1.Fill(this.DataSet1);
this.DataGrid1.DataBind();

Now I want to set up couple of Filter options.
Since I already have all the data I don't want to send another sql to database.

How do I send Sql to data set and recreate the same datagrod with filtered data?

Thanks

Can I somehow convert an array to mimic a variable arglist?

dpmIris31-Mar-06 3:15

OK, my problem is I am using an unmanaged function similiar to the printf function, in that you can pass a variable number of arguments of any type.

If I knew the number of objects I am getting I can simply call the function like

//3 items :

print("%s%d%f", obj1, obj2, obj3);

If I don't know the number of objects I am getting how can I convert them/add them to the argument list ? - printf(format, objects ??)

If I just pass an array the unmanaged function doesn't work. Its like the unmanaged code should be getting several arguments but I imagine its only getting the one, a pointer to my managed array ?

So basically I don't want to pass one argument(which is an array). I want to send the elements of my array as seperate arguments mimicing passing several arguments.

Define the amount of parameters you need in the DllImport definition.

The C++ definition is say
printf(const char* format, ...)
My DLLImport is

[DllImport("xxx.dll", EntryPoint = "printf")]<br />
public static extern bool Print(String format, __arglist )

In my C# function I am getting an array of objects of varying lengths.

void func(Object[] objArr)<br />
{<br />
 // Now I will construct the format string based on the type of objects I am passed.<br />
 String format = "%s%d%lf"; etc....<br />
 ..<br />
 // Then I want to call the Print function passing the elements of the array as the  arguments to match the format string.<br />
 <br />
 Print(format, ??!?!? );<br />
}

Hi,

Is there a way of locking a forms position (i.e., without removing its border, which makes it look bad!)?

Thanks.

Yes. Override your form's WndProc() method and handle the WM_MOVING[^] message. Specifically, return the form's current pos and size to Windows. This will cause the form to be immovable.

Hello,

I wan't to duplicate a toolstripmenuitem. The problem is that I don't have found a solution to duplicate an event. All other properties which I need I can access. I want to duplicate the event, because in that part of the code I don't know which eventhander is registerd.
Is there any way to do that?

How to create a window like mIRC's status window?

alexjstubbs31-Mar-06 2:14

31-Mar-06 2:14

I need to create a window like mIRC's status window, in which can display text (with fonts and colors) as well as when you select the text, it automaticly copies it to the clipboard but does not stay selected.

I need to do this in win forms. I would also like to extend it to display images... i know his is a custom drawn window... how could i do this same thing in winforms? any ideas?

One way that you could do this is to set up the status window as a panel and create your own Paint events. You would then use the graphics object for the control to do the drawing you need done. Changing font characteristics and doing g.DrawString will handle the multi-colored text. g.DrawImage would handle graphics at some point. The last piece would be more difficult with a panel, but there is probably a windows API you could hook into for that.

Yeah, I had that idea and its kind of what i've been doing in a way. But i really cant find any ideas on how to copy drawn text, except for going through all the trouble of cursur position and position of the string displayed on the panel, and creating some sort of my own draw code to look like its selecting text, and copied (and actually copy it)... etc.

But thats just way too hard =P

Hello

I have a usercontrol with a number of childcontrols. One of these control's got a 'EnabledSpecial' property. I would like for this to be set instead of the controls 'Enabled' property when the usercontrols 'Enabled' property is changed.

How do I go about achieving this?

/regards Magnus

EDIT: Fixed, used OnEnableChange on usercontrol and looped through all childcontrols.

Reverse Name Assignment

Shadow Sprite31-Mar-06 0:32

Shadow Sprite

31-Mar-06 0:32

Hello,
I am new to this site and new to programming. I am stuck. My assignment states the following: We need to write a program that will read in a string of any length and then display the reverse of the original string, the original string in all Caps and in all Lowercase letters. When reversing the string, the letters should be reversed with the appropriate capitalization applied to all letters.

Sample output in bold.

What string would you like to convert? John Smith
Reversed String: htimS nhoJ
All Uppercase: JOHN SMITH
All Lowercase: john smith

I figured out Uppercase and Lowercase but not reverse or even how to tie it in to the rest. We are using the console applications in Microsoft Visual Studio .NET 2003. Any Help would be greatly appreciated. Thank You!

You are lucky that I had this code lying on my computer becouse I usually don't do other people's homework;)

class Program
{
	static void Main(string[] args)
	{
		Console.WriteLine("Input a string:");
		string inputString = Console.ReadLine();

		Console.WriteLine("All lowercase: " + inputString.ToLower());
		Console.WriteLine("All uppercase: " + inputString.ToUpper());

		Console.Write("Reveresed string: ");
		for (int i = inputString.Length - 1; i >= 0; i--)
			Console.Write(inputString[i].ToString());

		Console.ReadLine();
	}
}
