You need a modal dialog, try calling ShowDialog() instead.
var wdApp = new ActiveXObject("DiscussInterface.Class1");
wdApp.ShowDialog();

DiscussInterface.Class1 has no method "ShowDialog()".
and
when I change the f.Show() to f.ShowDialog(),it disappears immediately,too.

Sorry, I missed the fact that you were embedding a Form within Class1. Why don't you change your code around so that it is inheriting from System.Windows.Forms.Form? That way your not wrapping all the method the Form is providing you. ShowDialog() works for me.

Greetings all,
Comming from a unix/C background here I'm attempting to get the length of a string entered from the user. Here is some code...
namespace _250_question_1
{
class HowEasy
{
public int pointVal(string input)
{
int word_count = 0;
for(int x = 0; x <= strlen(input); x++)
if(input[x] == " ") word_count++;
if(word_count <= 3) return 250;
if((word_count == 4) ||
(word_count == 5)) return 500;
if(word_count >= 6) return 1000;
}
static void Main(string[] args)
{
string user_input;
Console.WriteLine("Please enter a string:");
Console.ReadLine(user_input);
pointVal(user_input);
}
}
}
The algorithm is how I would do it in C, However in C# I can't compare an array element (string[x]) for equality. Not only that, I would normally use strlen() in for() and apparently the standard C library isn't used. Could anyone rewrite this in C# so I can see what's going on, or at least give me some hints?
Thanks all!!

Use a regular expression, or even better, Split and count your array.
To get the string length, just use the Length property.

How about using some of the methods and properties of the String class. An example:
string s = "Nick Parker";
int len = s.Length;
Console.WriteLine("string:{0} length:{1}", s, len);

public int pointVal(string input)
{
int count = input.Split(new char[] {' '}).Length - 1;
if (count <= 3) return 250;
if (4 ==count || 5 == count) return 500;
if (count >= 6) return 1000;
}

 Hello I have a technical question:
I am working in a project.my code is in a seperate DLL ,separate class.The point is it works correctly on most of the inputs.However on some inputsit gives the following alert box message:
An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll
Additional information: Index was out of range. Must be non-negative and less than the size of the collection.
I know this type of exception,but the problem is when i place a breakpoint (anywhere in the class,even in the constructor)to start debugging,in the debug mode itwould give the following message:
There is no source code available for the current location.
SHow dissassembly automatically
and ofcourse the cursor wont be standing on any line,to allow me to start debugging.
Does this mean that the first exception occured in another class or DLL which is not related to my code?
Thanks a million

hi,
your Wrote :'System.ArgumentOutOfRangeException' and 'ndex was out of range. Must be non-negative and less than the size of the collection' - > Please check your collection , whether you are not trying to access which is not there in the list.
You Wrote :Does this mean that the first exception occured in another class or DLL which is not related to my code?
Here you are assumption may correct. Try to use proper error handling methods in your .dlls. Otherwise try to throw exception to your base.
//code in dll file.
public void add()
try
{
//something
}
catch(Exception Ex)
{
throw Ex;
}
//code in your application.
try
{
dll_instance.Add();
}
catch(Exception Ex)
{
Messagebox.show(Ex.StachTrace.ToSting());
}
//Here you will get information from where error occures.

You may be able to step into the code of the separate DLL if the debug symbols are available for it.
Is the dll raising the exception written in managed code (C#, VB.Net etc)? If so, compile it in debug mode and reset the reference in the calling application. You should be able to then either set a breakpoint immediately before the call raising the exception and "step into" the code that's having trouble, or just set the debug feature to break into the debugger on all exceptions.
The previous poster was correct, however, the error you're seeing is because somewhere you've got code indexing past the end of an array/collection. This commonly happens for a couple of reasons:
1. Developer forgets that arrays are 0-based (so the index of the last element is Array.Length - 1)
2. The collection is being shortened (items are being removed) within the code while an iterative loop moves from lowest to highest index (e.g. 0-10). Since each removal essentially re-indexes the collection, eventually an index will be selected that is past the end of the array.
Hope this helps

Hi!
I'm looking for two controls, one to do Gantt diagrams and another one to implement an Calendar in wich I could post dates (like outlook for example). Does anyone know any free control implementing one (or both) of this funcitonalities?
I'm developping a Windows Forms application.
Thank you!
Jordi
PS - If I don't find it I will try to develop them. If I do it i'll post them in this fabulous website!

You are looking for some thing like 'Planner'. Microsoft Project Planner ?

Yes, something like that but I don't look for a program, I look for a control to be added to my .NET application. Do you know any free control like this? I don't need an espectacular control, a simple one implementing Gantt diagrams or a calendar would be perfect.
Thanks!

I look for a Calendar in wich i could implement and Scheduler. I would like to be able to insert some text in a specific date. It is not possible in MonthCalendar, isn't it? I look for something like Outlook.
Thanks anyway!

Hello,
What is the CultureInfo format string for a decimal that I want to show with no trailing zeros?
1.000 is formatted as 1
1.100 is formatted as 1.1
1.010 is formatted as 1.01
1.001 is formatted as 1.001
Thanks in advance,

If you call the ToString method of your decimal the trailing zeros are automatically trimmed. To ensure the decimal separator is always a point provide a CultureInfo that uses this decimal separator, e.g.
CultureInfo culture = new CultureInfo("en-US");
decimal x = new decimal(1.010);
MessageBox.Show(x.ToString(culture));

Thanks for your reply, but that didn't solve my problem.
I have a DataGrid control, to which I assign a DataGridTableStyle. One of its DataGridTextBoxColumns is supposed to display a quantity of the product sold. In most cases, you only can get products in multiples of 1 (bottles of water) but in rare cases (oil for example, the app is for a car wash) it can be sold in fractions.
The data field from the MSDE database is a decimal with scale 4, so the DataGrid always displays the value with 4 decimals. I'm trying to set the DataGridTextBoxColumn's Format property so it trims trailing zeros, but I can't find how. I've set it successfully for other columns (currency) but not for this one.
Any more ideas?

I'm trying to do something like this:
OpenFileDialog xOpenFileDlg = new OpenFileDialog();
xOpenFileDlg.Filter = "All Images|*.png,*.bmp,*.jpg,*.gif,*.tif";
xOpenFileDlg.ShowDialog();
(i.e. make it show all the png, bmp, jpg, gif and tif files, but not anything else) - but I can't work out the proper syntax for the wildcard
can anyone help?
