I knew there had to be a better way and it would present itself eventually.
I've just never had need of the Path class before (or didn't know I did).
The FileInfo class really ought to have this member as well.

instead for using the split function you can directly use the Path class of IO
sample code is

System.IO.Path.GetFileNameWithoutExtension (@"C:\CCCRM\CCCRM\bin\release\cccrmNeeded.dll");

and this will return the cccrmNeeded.

If it's not on disk it's not a file. Big Grin | :-D

Once written to disk you can use Process.Start to "open" it with its associated application. That's what I do.

Hi All,

This is my first post in this forum that is full of excellent information I'm so glad I found it.

I have a c# program I'm working on it opens an excell file and displayes the results in a DataGrid at the moment I have it selecting the cell with the code below.

//Set excel sheet range
exr.SheetRange = "A1:C5";

What I'm trying to make it do is select the data from cells M3, M4, E5, G5, H5, R5 then go to cell G7 and read till the last empty cell to the right of G7 then read down from G7 to the last empty cell.

Any one know how to do this?

Hello

Not much to say but the idea is: your problem can be solved with 2 loops (on rows and columns)

try it and reply if not succeeded.

Hope u be happy.

KeyCode to char NumPad problem [modified]

DaveyM6929-Jul-08 13:09

29-Jul-08 13:09

I'm overriding OnKeyDown in a class derived from TextBox.

The new TextBox has several functions, one of which is to only allow a valid decimal (unsigned) value to 2 decimal places. All is well and decimal places are added if necessary - unless the MaxLength is exceeded when the formatting is done in OnValidating / OnLostFocus.

I figured the easiest way would be:
If the key pressed is a number then build the final string in memory, check the length of that against MaxLength and supress the key press if it would exceed MaxLength.

The problem is getting a char or string value from any of the KeyEventArgs properties if the number pad is used. Casting or converting to char returns a, b, c ...

Any ideas?

Edit:
Temporary solution

char digit;
if (e.KeyCode >= Keys.NumPad0 && e.KeyCode <= Keys.NumPad9)
    digit = Convert.ToChar(e.KeyCode - 48);
else
    digit = Convert.ToChar(e.KeyCode);

A) Have you considered using a NumericUpDown rather than a TextBox?

B) Have you considered using KeyPress rather than KeyDown?

private void textBox1_KeyPress ( object sender , System.Windows.Forms.KeyPressEventArgs e )
{
    char digit = e.KeyChar ;
}

The NumericUpDown is not an option.

I considered KeyPress but it's not raised by non character keys which could potentially screw up other functions Frown | :(

Thanks anyway.

Aaaanyway...

Perhaps a Dictionary<Keys,char> will do the trick.
But do you really need to know what character was pressed?

And I expect you know about .Handled and .SuppressKeyPress

Hi,

I have a base class called "UserInterfaceBase" and I'd like the user's programmer can create and plug their own interface.
Is there anyway to do it? Of course the project won't have a reference to the user "homemade" interface, so I think that's the problem I'm having.

Type tUI = Type.GetType(loader.InterfacePDV.InterfaceClass, false, true);
if (tUI == null)
    tUI = Type.GetType("JRFW.Appl.CM10.CPDV.UI." +
        loader.InterfacePDV.InterfaceClass, false, true);
if (tUI == null)
    throw new TypeLoadException(loader.InterfacePDV.InterfaceClass);
PDVUI = (IPDV)Activator.CreateInstance(tUI);

It always throw the TypeLoadException exception.

Thanks,
Dirso

Sounds like you're trying to do plug-ins. Have you looked at System.AddIn in the latest .NET framework?

Hi,

Thank you so much!!! It looks like nice and easy to use, but since I making a cross plataform software I have to be sure using namespaces implemented in mono framework too.
I just made a test and even if I add the references to the application project, it still throws the exception. I'm now using the type's FullName, and still no luck. Do I need to do anything else?

Thanks,
Dirso.

Updated Code:

Type tUI = Type.GetType(loader.InterfacePDV.InterfaceClass, false, true);
if (tUI == null)
    throw new TypeLoadException(loader.InterfacePDV.InterfaceClass);

Then have you seen Mono.AddIns[^]?

If you're still set on doing it your own way, you'll need to start by calling Assembly.Load on the assembly built by the 3rd party.

Isn't there a list of languages somewhere in .net?? I know I have seen i somewhere but searches yield too many non related results. I just need to have a text box that will list a bunch of languages to store the language that the person filling the form speaks.

Make a list with the languages you already have, and let the users add other languages to your list if not displayed there. Big Grin | :-D

This will list all the cultures available if that's what you're after?
(Add using System.Globalization; to the top of the class)

CultureInfo[] supportedCultures = CultureInfo.GetCultures(CultureTypes.AllCultures);
for (int i = 0; i < supportedCultures.Length; i++)
    Console.WriteLine(supportedCultures[i].DisplayName);

clickonce register COM problem

Hello

VS 2008

The 2 users that have tried to run the application get this error.

"CATWinApp has encountered a problem and needs to close"

"An unhandled exception ('System.Runtime.InteropServices.COMException') occurred in CATWinApp.exe [2220]. Just-in-debugging this exception failed with the following error: No installed debugger has just-in-time dubugging enabled. In visual studio, just-in-debugging can be enabled from Tool/Options/Debugging/Just-in-time."

The users don't have any visual studio. Only the 2.0, 3.0, and 3.5 framework. Which is needed to run the application. They are only users so they don't have any development tools.

In my application I have a ActiveX control (COM), called "VaxSIPUserAgentOCX.ocx" I have registered this on my developer box using this: "regsvr32 VaxSIPUserAgentOCX.ocx".

The application run ok on my computer but no one elses.

In my references when I select them in the properties name in my application I have the following: AxInterop.VAXSIPUSERAGENTOCX and Interop.VAXSIPUSERAGENTOCXLib. In the properties I have local copy set to true.

I think the problem could be that is not registered on the users' computer. However, I am not sure how to register them. I have tried "regsvr32 VAXSIPUSERAGENTOCXLib" But comes up with "Entry point cannot be found".

Then I go to publish I click on Application Files and select Include (Auto) Requried for both AxInterop.VAXSIPUSERAGENTOCX and Interop.VAXSIPUSERAGENTOCXLib.

Could this ActiveX be causing the problem? And if what is the best method to solve this problem?

Many thanks for any advice,

Steve
