There is an MS knowledgebase article regarding this exception here.[^]
Does that help at all?

Hi,
I am passing an object of a class declared in my C# code to an unmanaged VC++ dll.
If my class contains an int/double/char and may be some functions then I can get their values in the dll. Also I can modify the values there and the modified values I can get in my C# code. So it works fine.
But if I include a string in my class then I can get the values of other variables except the string. And if I modify ANY value in the dll then it does not get reflected in my C# code.
I am unable to proceed. plz help me...

 Hi guys, I have a question... I have managed to program a simple game, but I need help in creating a starting menu. For example, the options would be, "start", "high score" "help" "exit".
I hope anyone with game programming can help me out soon. Thanks in advance!!!

some more details would be nice.
How have you made the game, using GDI+, directX openGL?
If you've used GDI+ just use windwos forms buttons for your options.
Otherwise give a bit more info.
Cheers

Hi,
is it possible (and how? ) to write an application, where I can get some informations like "artist" or "title" from a streamed file, which was played by a WindowsMediaPlayer ActiveX, which is embedded in the loaded webpage?
Thanks in advance, Randy

Hello,
How can I sort a DataGridColumn which has Alphanumeric values such that
"Record No: x". Is there any property which I can use for this purpose.
Scenario:
I have 4 values in column R1, R9, R20,R10 and when I try to sort this
column in the DataGrid (by clicking the header) it displays R1, R10,
R20, R9. While I want to display R1, R9, R10, R20.
Is is possible. Thanks in advance

Would it be possible to pad the numeric portions with zeros? That should yield a more "accurate" sort.

Hello,
No! the given scenario was just to make the problem clearer. I have sort more complex values in the realtime application, something like "Buy Price 1.2034", "Sell Price 2.382", "Market Price" etc. It means that some values can be alphanumeric but others will be just strings.
Can anyone suggest a generic solution to this problem.
Bye

It sounds like you need normalization, not a different sort routine. In the example you offer, there should be 3 columns - BuyPrice (decimal), SellPrice (decimal) and MarketPrice (decimal).
If you're using a single column to hold three different pieces of data, you should think about changing the way the data is stored and/or displayed.

Hello,
It is not the case of storing data in right way or something, it is just for the user friendliness, the way user wants to see it.
By the way, there should be only two columns, Price and Type . Any luck with the actual problem :s

You can always display normalized data in a non-normalized way using SQL functions, string concatenation or by simple control placement. How you display data to the user should not dictate your data model. They seldom coincide.
In the example you provided, you would need three columns to hold price information unless you decided to either duplicate all row data for each price type, or move prices to a separate table. One price column in the same table would not cut it.
As far as "the actual problem", there isn't one. You're trying to use standard sort routines to sort data in a non-standard way; what's more, your data appears to be stored in a fashion that is not conducive to ever having meaningful reporting or display filtering options.
If you are completely devoted to storing your data in the manner you suggest, then I would advise investing some time learning how to implement the IComparable interface, and create your own collection class that's sortable. Please note that this option is less than optimal, to put it mildly.

Hi all, i'm using System.IO.File to copy a shortcut to my application into the startup directory but on Windows 2000 machines the "Target" part of the shortcut is being renamed to my1~.exe instead of myshortcut.exe. This causes the applications process name to be changed to my1~.exe instead of myshortcut.exe which causes me problems in other applications. Anyone able to tell me how to either, change the target name back to what it should be after the file has been copied or prevent the name from being changed in the first place.
Cheers

Go to Microsoft and look up the Office automation objects. I think that they should tell you everything that you need to know. You will likely need to get what are called the PIAs (I dont remember what they stand for now... something interop assemblies) which are essentially COM objects. With these you can pretty much interface with office directly.
I hope that this helped, email me if you need more help,

Hi!
I'm starting to create my own ebook reader as ms reader or mobipocket reader but I don't know how to start from the begin.
Please tell me some intruction, what elements I need, .....
Thanks for your help, I want to do it for convert all my documents to ebook!

I think the question you have to ask yourself is what elements do you want.
Write down a list of features that you want. Then write down everything you will need in order to create that feature. If there is anything in the list that you don't understand then find books or articles on the topic and read them. Design your application and then write the code for it.
If there is anything that you get stuck on when you are coding it then I'm sure we can help you better than we can now.
Do you want to know more?

I'm so amazing to get a fast reply, I guess my application is similar an documents reader as mobipocket.com, eReader.com. I have some ideas about my projects:
+ Can compile html, oeb (open ebook file), text, .doc file format( from the begin I think it support for text and html files first  ) to a file can store and compress it to make a small size)
+ The reader can read my files and tranform (HTML) it as one or two page similar the way ms reader or ereader.com show ebook for everyone.
==> I think some items I need is:
+ HTML, XHTML, OEB Render -> read and tranform with small tag support
+ HTML, XHTML Pager <==this is very importan because it control the application speed.
+ How to compress my file read it from my reader
+ Compression and Decompression methor, I'm look for how to Decompression fastest and got a minimum of RAM resource.
I'm very thanks for all suggest, demo programes especial source code about it.

Is there any way to derive from one of the menu classes in order to modify the control in which the MenuItems are displayed (modify its Region, override its OnPaintBackground etc) in order to obtain a custom shaped menu ? Currently i have implemented one such menu by using a Form, but that got me into a lot of trouble and i have not even implemented the full functionality of a normal ContextMenu yet. The most obvious problem is the fact that the 'menu' Form needs focus in order to be able to receive any Click event, so the 'parent' window will lose its focus and be displayed with a 'grayed' title bar when the 'menu' becomes active (i fixed that by overriding the 'ON_NCACTIVATE message of the parent window, but i`m still unsatisfied with the result). Some suggestions will be most welcome. Thank you

hi
I am facing a problem.
i am having a ushort value (ushort val), and i want to campare it with two byte values(byte b1, b2).
how can i do it? 
if I can convert the ushort to two seperate bytes or vice versa the problem can be solved.
i.e. the ushort which is made up of two bytes is to be decomposedinto two seperate bytes
thanking in anticipation
mahesh

Use simple mathematics:
byte x = 1;
byte y = 1;
ushort z = 257;
if (z == (x * 256 + y))
{
}

You could also try using the System.BitConverter class.

I need to write a console app that will allow me to get files out of SourceSafe. I can not make a reference to the type lib in the project. SO far all the samples with VSS use early binding. I have been able to get the late binding to work with Excel, but I am not getting very far with VSS. Anyone out there using Late Binding with VSS and C#? The reason I need to do late binding is I need to support version 5 and 6 of SS. If there is another way to ensure I can work with different versions of SS I am open to any suggestions.

how to upload a directory and save it to oracle database using C#
|
|
|
|
|
I'm not sure I understand what you're trying to do completely, but it sounds like you're saying you want to store a directory's worth of files in Oracle. Is that correct?
If so, it should be pretty straightforward. You'll want to iterate over the files in the folder (and possibly recurse over any subfolders), then for each file you encounter, read it into a stream, then write the stream to BLOB data in Oracle using a command and parameter(s). For reference, you may want to read up on the System.IO.FileStream class, the managed Oracle data client types, etc.
This is a high level answer because the question was equally non-specific. If you have more detailed questions, I'll be happy to try to help. I've done some of this in the past.
Things you may want to consider are:
1. Is file size a concern?
2. Do you care what the file extension is?
3. How do you want to identify files in the data record (name only, source path and name, etc)?
4. Are file permissions an issue when reading files or extracting them from the database?
Hope this helps.
