dear ,
okey, i try to "give my hand"..
I hope, it can help you
1. Check your system computer!!!
You have to use : Processor > 2.0Gb
Memory > 1Gb
Free Hardisk > 2G
2. Check your Operation System(OS)!!!
Maybe your OS is too many program
Maybe your computer is infected by virus
So you can upgrade and clean your computer!!!
Have nice day, n good luck
thanks...

Hi Deepaks3 
Do you want instant notification?
By that I mean - do you want a postback the moment someone changes a value, or do you just want to check the values of the dropdownlists when the user submits the page again?
Kind regards - Jakob

No. You can open certain applications in MDI windows, but only if they are ActiveX or .NET controls themselves, at which point you could place those controls on your MDI window, then open the file in that window. For example, you should be able to add an AdobeReader ActiveX control to a MDI window, then use that control to open a particular PDF file.
But you certainly cannot do this with all apps; only those that are components usuable from other apps.

Hi every one ,
I'm programming with C# and I wrote below code :
command = new System.Data.Odbc.OdbcCommand();
command.CommandType = System.Data.CommandType.Text;
commString = "INSERT INTO MyTable (MySign) VALUES (@MySign)";
command.CommandText = commString;
command.Connection = SqlConn; //is defined
command.Parameters.Add("@MySign", OdbcType.VarBinary).Value = MySign;
SqlConn.Open();
command.ExecuteNonQuery();
SqlConn.close()
but I get <must declare="" the="" scalar="" variable="" "@mysign"=""> error,what is my mistake?
Please help me.
yours sincerely.

ODBC doesn't support named parameters.

Dear Guffa
Thanks alot for your reply,
But do you know how can I insert the variable (Byte[]) in the sql server?
I 'd like to connect to DB with odbc and I want to insert it a byte array variable,what is the solution?
yours sincerely.

Use unnamed parameters.

HI
yes this is byt array
But i have to read 4 consecutive byte in a uint variable so that i can use it as a offset.How can i do this

Do not repost your question.
You should have replied to my post in the previous thread!!
Are the values of your bytes stored in decimal or hexadecimal?
|
|
|
|
|
|
If your values or store in hex Right to left order Like this:
Byte3-byte2-byte1-Byte0, and each byte represents a hex value from 1-15
So your read byte0,
Then byte1 and multiply it by 16
Then byte2 and multiply it by 256
Then byte3 and multiply it by 4096
It's a simple Hex-dec conversion, and I hope I got you right..

Hi
My byte array store hex values
take an e.g
00 ea d4 00 This is four byte .how can i read then in as it is in a variable so that myvariable=d4ea
in vc++ there is memcpy function there should be?
|
|

I believe that you have not stored hexadecimal digits (0-15) in the bytes in the array, but byte values (0-255)? Am I correct?
Shift the values and add them together:
uint b1 = theByteArray[somewhere];<br />
uint b2 = theByteArray[somewhere + 1] << 8;<br />
uint b3 = theByteArray[somewhere + 2] << 16;<br />
uint b4 = theByteArray[somewhere + 3] << 24;<br />
<br />
uint offset = b1 + b2 + b3 + b4;

Your statement is contradictory. Are you storing a hexadecimal string in the byte array, or are you storing bytes like 00 ea d4 00?
If you are storing bytes, do you want a value like 00ead400 or just the middle bytes ead4?
Are you storing the bytes in reverse order, i.e. Motorola style, or are you storing them in regular Intel order?
