I'd often store values from an enum, that relate to selections being made, etc.

Hi everyone,
I developed an Outlook Addin that is supposed to open a certain application depending on the subject of the Email that I receive. The app works fine but after clicking OK to all MessageBoxes, I get the ff error:
Object reference not set to an instance of an object.
************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

Outlook.MAPIFolder inbox = this.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
/*Retrieve and count unread messages from Inbox */
Outlook.Items items = inbox.Items;
Outlook.Items unreadItems = inbox.Items.Restrict("[Unread]=true");
MessageBox.Show(string.Format("The number of Unread items in Inbox = {0}", unreadItems.Count));
// If the mail item matches the specified filter,
// open The Dragger application
foreach (Outlook.MailItem mail in items)
{
//if the mail's subject has ecs, open The Dragger
if (mail.Subject.ToUpper().Contains(filter.ToUpper()))
{
//Open The Dragger
MainForm main = new MainForm();
main.ShowDialog();
}
else
{
MessageBox.Show("No new messages for ECS!!!");
}
}
Please help...

Could you point out this line in your code above?

Hi Le Centriste,
This is Line 31:
//if the mail's subject is ecs, open The Dragger Application
LINE 31--> if (mail.Subject.ToUpper().Contains(filter.ToUpper()))
{
//Open The Dragger
MainForm main = new MainForm();
main.ShowDialog();
}
else
{
MessageBox.Show("No New Messages For ECS!!!");
}

I would check for nullity of either mail.Subject or filter.

Hello everyone,
I just wanted to know if it possible to have number of panels (let's say 4 panels) FILL DOCKED into the same window form. It appears when I dock them the first panel is docked to the Windows Form, the second panel is docked to the first panel which has already dicked to the windows and the third panel is going to be docked into the second panel rather than the Windows Form.
I hope I managed to make sense!  )
Is there any way I can have all the panels docked into the Main Windows Form and overlapping one another?
Thank you very much and have a gear day.

Hello,
No, you only can dock one control.
Maybe the Anchor property helps you out.
All the best,
Martin

go with Anchor tag man it will help you.

If I have more than one version of one assemblies,
then how'll I use old version.
(how/where to specify version number?)in my application?

Edit AssemblyInfo.cs. You will see a line that says something like
[assembly: AssemblyVersion("1.0.0.0")] Change it to whatever version you want.

After all is said and done, much is said and little is done.

I'm writing a wrapper for a win32 frame grabber library. When an image is aquired by the grabber my win32 wrapper DLL needs to pass the image data (stored in large WORD arrays) to the C# front end. I'm calling into the managed code from the win32 DLL via a callback delegate when an image is acquired and ideally I would like to pass the image data in this function call as well but i'm unsure as to the best way to accomplish this? I've looked around and found plenty of information about passing arrays and pointers to unmanaged code but not the other way. If possible I would like to minimise any overheads caused by copying the large amounts of data. Any suggestions would be appreciated.
Thanks.

C# can only work with unmanaged memory through pointers or methods like Marshal.ReadByte(). If you want to have the buffer directly be treated as an array, it must be originally allocated by managed code. One way to do this is to create an array, pin it, get an address to it, and then use that as the data buffer:
short[] buffer=new short[dataLength];
GCHandle handle = GCHandle.Alloc(buffer, GCHandleType.Pinned);
IntPtr bufferPtr = Marshal.UnsafeAddrOfPinnedArrayElement(buffer, 0);

Hi,
I agree: if the native API allows it, allocating a managed array, and passing it
to the unmanaged world is the best way (BTW dont forget to free the GCHandle).
If the API does not support this, and the native function takes care of its own
allocation, then all the data will have to be copied in order to create a managed image;
and of course you then somehow must free the unmanaged memory.

Hello everyone, im using VS2005, i have a webpage in which i have a FileUpload control, and a Submit button. On the Submit button (.cs)page, i call this line :

I have VS2005 and that image doesn't exist on my system either. How are you getting the path to the image, allowing the user to browse? Perhaps try and hardcode the path and let me know what happens.
There are 10 types of people in the world, those who understand binary and those who dont.

yes u right, i have a Fileupload control, in this a text box and Browse filed exists, user clicks on the browse button and the path is set into the text box, so that y me using that line of code ::
//string fname = FileUpload1.FileName;
//Response.Write(fname);
//get the image file into a stream reader.
FileStream FilStr = new FileStream(FileUpload1.FileName, FileMode.Open);
BinaryReader BinRed = new BinaryReader(FilStr);
as u see the comments stmt codes when i used this one, or hardcode the path in the FileStream line , it gives me the same error,
plz help me how can i get rid from this.
Thanx in Advance.

ASP.NET's working directory is C:\WINDOWS\system32\, and besides, you cant use the client path on the server, thats just absurd!

Hi Leppi ur link not working at my side, this page is not opened.

Hello everyone,
I have a Window Application which is currently using TabControl to have number of pages with different functionalities and controllers. I was wondering if I can replace the TabControl with something rather like Microsift OutLook "Using Buttons to change the page". I just wish the pages not to have any tab so the page appears to be the only the form.
Thank you very much and have a great day.

Hello,
I guess you have to build the UserControl yourselve or look for some comercial controls!
All the best,
Martin

Hello Martin,
Thanx for the reply, mate. Would you by any chance know of any comercial controls that would be able to produce that?
I have looked into Professional UI Solution and Dev Components and it appears they don't have this kind of control.
Thank you very much for your help.
