Hello everybody.
I have a problem.I'm working with VS2005 and my project is a C# windows application. I define an array of buttons but I don't know how to make EventHandler for this array;
Thanks for all.

for (i=0; i < ...) {
btnArr[i].Click += new System.EventHandler(NameOfYourClickHandler);
btnArr[i].Tag = i;
}
Then declare a function called NameOfYourClickHandler:
public void NameOfYourClickHandler(object sender, System.EventArgs e) {
MessageBox.Show(((System.Windows.Button)sender).Tag.ToString());
}

Hi all,
Is there a way to say Process.Start("THEFile") and say with what program to open it in?

Process oProcess = new Process();
oProcess.StartInfo.Arguments = "D:\\Temp\\MyFile.txt";
oProcess.StartInfo.FileName = "notepad.exe";
oProcess.Start();

Hi, Thank you... I will try your way in a moment.
I have come across this... Process.Start("excel.exe", Convert.ToString(Path) + "\\" + Convert.ToString(FileName) + ".xml")
I get an error saying 'c:\program.xls' not found....
BUT the file i want to open is a xml file....
i think it reads the path up to the first space and then continues...
The Variables Values are:
Path = @"c:\Program files\Reports"
FileName = "CL"
Please help

char cQuote = Convert.ToChar(34);
Process.Start("excel.exe", cQuote + Path + "\\" + FileName + ".xml" + cQuote);

I've created Resource.resx, which has some images. The resources are named as Res1, Res2, Res3 etc.
I'm dynamically creating some PictureBoxes, using this function:
public PictureBox AddNewPicBox(int n)
{
Create a new instance of the PictureBox class.
PictureBox picBoxLine = new PictureBox();
this.Controls.Add(picBoxLine);
picBoxLine.Width = 25;
picBoxLine.Left = (n-1) * 25;
picBoxLine.Top = 1;
picBoxLine.Tag = n;
}
In this function, I want to set the Image property of the newly created PictureBox depending on parameter n.
For eg. if n = 1, I want
picBoxLine.Image = ResourcesImages.Res1;
When n=2,
I want
picBoxLine.Image = ResourcesImages.Res2;
Any idea how to do this?

ResourceManager res = new ResourceManager("MyResourceProject.Properties.Resources", Assembly.GetExecutingAssembly());
picBoxLine.Image = (System.Drawing.Image) res.GetObject("Res" + n.ToString());

Hi
I am using static binding i.e the use of dll of MS OUTLOOK 2003 in my Windows application to extract FROM,TO,CC,BCC,MESSAGE email addresses and their names etc. and store it into an MS ACCESS database. The module is working fine in my machine and also in client machines, but some of the clients are complaining that they are getting the error at the time of running the module. They are also using MS Office Outlook 2003. They are getting the error when try to run the application.
The error is like this:
System.IO.FileNotFoundException: The specified module could not be found.
I think sometimes CLR fails to load unmanaged dll of OUTLOOK. I have tried by using most of things but till now there is no success. All the dlls are present in applications root folder.
Is there any idea?
regards

Elena,
Try the utility FUSLOGVW.exe. Enable tracing and try again. It should tell you in which directories the module was looked for and what happened. It may help you in diagnosing the problem.

Thanks for your reply.
I am using FUSLOGVW.exe and getting the log below but still it is unsolved. Please give some suggestions.

Well, this log is not related to Outlook but to the assembly "TestApp.resoures"...

Thanks again for reply.
Can you give any idea how to fix the bug.

Dear friends, consider the following 'dirty' html code:
<P> </P> <P> </P> <P>[BodyStart]</P> <P>Soccer is our national game</P> <P>[BodyEnd]</P> <TABLE cellSpacing=1 cellPadding=1 width="100%" border=1> <TBODY> <TR> <TD>[PT_FName]</TD> <TD></TD> <TD></TD></TR> <TR> <TD></TD> <TD></TD> <T
In the above html code, there is a special tag [BodyStart] and [BodyEnd]. I want to extract this tag from the html. Moreover, i also want to extract the text written inside this tag. How can i do so in C#

Look for the regular expressions subject, there are few snippets that will extract exacly what you need.

Hello,
I'm programming my own application in C#, and I need to know the type of an object in execution time. I need to do a dynamic cast.
In C++ there is dynamic_cast<>, but I don't know how to do this in C#. I expect that you can help me.
Bye!
|

Type t = myVar.GetType() will give you the type.
For dynamic conversion, you might also do something like this:
public bool compare(object a, object b)
{
if ((a is int) && (b is int))
return (int)a < (int)b;
...
}
regards

It has been a while since I did any C++, if the following doesn't help can you remind me of the properties of a dynamic_cast.
There are two casting operators in C#
SomeClass castedReference = (SomeClass)objectReference;
SomeClass castedReference = objectReference as SomeClass;
The first will cast an object and raise an exception if the cast fails. You can cast to a the base, or if you have a base reference already you an cast to a more specific derived version.
The second will cast an object and return null if the cast is invalid. Again you can cast to any valid point on the inheritance tree for that object.
There is also the is operator which you can use to tell if an object is some particular type. e.g.
bool isSomeObject = objectReference is SomeClass;
The result will be true if the referenced object is at a valid point on the inheritance hierarchy for given type.
Does this help?

Of course. This helps me very much. What a great explaination!
Thank you!

Don't use is when your casting because first you must find its type and then make the apropriate cast. The as statement is a much better choice as it does both type checking and casting in one operation. Using the is way forces you to check the types type twice because you must first check the type using is and then cast which also checks the type. The as will return null if it not compatible with that type.
SomeObject sobj = new SomeObject();
ADifferentObject diffObj = sobj as SomeObject();

So, if you don't want to do two checks, what do you do if the reference you are casting may be null in the first place? How do you determine whether the null after the cast was because of an invalid cast, or because the reference was null in the first place?
