I would like to register a set of hotkeys for my TextBox
For example, when I press Ctrl+0 or Ctrl+N, the Text property of TextBox will be set to "<null>" string.
Any suggestion?

I have a tiff file that I need to dispay on a form. The picture box class apparently does not support tiff. I can convert the file to Bitonal but the image loses a lot.
Being fairly new to C# can someone recommend a way to accomplish my task of opening a tiff file into a windows form? (picturebox or whatever?)
thanks.

You are right. I was surprised the designer doesnt support it. Try it this way:
pictureBox1.Image = new Bitmap("C:\\test.tif");

Is there any other way to calculate network utilzation except using PerformanceCounter ??

I am wondering if there is way to keep the nice method descriptions, available at programming time, if you compile the class to .dll. Will be nice for fellow programmers when using my classes.

Yes. Use XML documentation (3 forward slashes), and go into your project properties and enable XML documentation file. Name the xml documentation file <yourdllname>.xml
When other developers go to use your dll, IDEs such as Visual Studio will realize there is a documentation file available, and will use that to populate intellisense.

Go take a look at NDOC.
http://ndoc.sourceforge.net
it is free and allows you to document your classes from inside your code and build a MSDN type class reference file that can be used within or outside of your assembly.

After you have enabled the xml docs ,then :
In commenting claases and methods just use before them
///<summary>
///Summary description for Your class or Method.
///</summary>
If you want to comment a parameter then use:
/// <summary>
///
/// </summary>
/// <param name="Your Second parameter name"></param>
/// <param name="Your First parameter name"></param>
as < summary >s stands to the method description and param to the parameters ,and you can use any number of parameters.

1 :When you reply just click on the message and then there is a link called reply just click on it ,instead of launching a new thread.
2 : Create a database and then any table in it called USERS for example ,and add fields called username and password ,etc... .
And then try to ckek it by using a datareader to check if it's in the database or otherwise.

I am trying to create a main table from a dataset that may have mutiple tables all with the same structure any clues. I need to end up with one table at the end where am i going wrong as i get the error table1 already belongs.
here is my code
//get all table into one ready to show and print
DataTable tblNew;
tblNew = dst.Tables[0].Copy(); //get the sructure and data
for(int i = 1;i
|
|
|
|
|
Do you mean you want to add all the tables in this dataset to that table ?after each other ?
|
|
|
|
|
the user suplies me with say 5 tables all schemas are identical, I want to take all the rows from the 5 tables and crew a new single table containg all the rows from the 5 tables so as i end up with one single table(then not interested in what happens to the original 5 tables) As I need to end up with dst.writexml with only one table being printed and not 5 as i can use that in my crystal report.
|
|
|
|
|
lets say that they are in an array :
DataTable[] tbls = new DataTable[5];
DataTable final = new DataTable("All");
for(int i=0;i<5;i++)
{
foreach(DataRow r in tbls[i].Rows)
{
this.final.Rows.Add(r);
}
}
Hope that helps.

I want to create an Access database on my PocketPC (WinCE4.2, PocketPC 2003 OS). Then using C# to populate tables, query tables, ...
From a simple search on Google.com I find that I must use ADOCE.NET but I didn't succeed to download it and also didn't see any control that I can use from Visual Studio 2003 (I created a project for Smart Mobile Device).
Is there any one has experiences doing such kind of work?
Best regards,

Hi,
In a interface i am using private access specifier , will compling will it give error or not, if it give error then what is that error.
thanks
|

|
|
NO! its not allowed to put any access modifier behind function defination in interface, be it private, public, protected or internal.

Using a private in an interface is illogical.
The private specifier is telling the compliler that the method/property/field is accessible to ONLY other members of this specific class. As interfaces have no implementation nothing could ever use something declared as private within an interface.
As a general note: Interfaces are definitions for part of an exposed parts of a class so that other code can see that a class implements an interface and therefore know that it can call certain methods or properties even if it knows nothing else about the class.

Hi,
if two methods having same signature but different return type then also we can say that is overloading?
Example:=
int sum(int x,int y)
{
//some code
}
string sum(int x,int y)
{
//some code here
}
Plz tell me, thanks
|
|

In my views, yes we can say this 'Overloading'
