I have derived a custom control from the DataGridView to enable pasting operation from the Clipboard. I am able to do almost all the operation of pasting except the following
Scenario :
1. Added the custom DataGridView to form
2. AlloUserToAddRows = true and I have also set some other required property of custom DataGridView
3. when I turn AlloUserToAddRows = true , VS adds a one default row to grid
4. so I used the following steps to reproduce the bug
a. I run application and paste the data in each cell individually on the default added row it does not add any additional row to grid
b. I copied some rows from excel sheet and tried to paste in grid by selected first cell (as current cell)
c. Programmatically, I have to calculate the number of rows required to add in grid for pasting operation which I did , and using this.Rows.Add(n); to add n number of rows (I also tried with Insert())
d. While using Add() function everything works fine except that the first row is moved to end of the grid (only in the above mentioned scenario; for everything else it works fine)
e. While using Insert () method overloads, I am getting the exception (on same line in debug mode) InvalidOperationException with message as “no row can be inserted after the uncommitted new row.”
5. I tried many things to get work around for this bug, however I didn’t succeeded
Anybody knows the any approach where I can either get rid of this bug or exception?
suggestions are also welcome!!
Reg,
Deep
Happy Coding

Hi,
I need to convert string which has EBCDIC, packed decimal and Endian data to byteArray to save it in the database. I tried the following code.
Byte[] updateByte;
updateByte = System.Text.Encoding.Default.GetBytes(strData);
//here, strData is the string
Here what happens is it converts some characters to '?' with decimal value 63. For e.g. abc(ASCII vale) after converting to EBCDIC i get [129 130 131](these are decimal values of the converted EBCDIC data). When i convert the string to byte array in order to save it in database, it changes all three characters(129, 130 and 131) to 63. This mostly happens with small case alpbhbets.
I also tried other encoding(EBCDIC-US) but this also changes more characters.
IMP: Please note that the string that i need to convert to byte array contains EBCDIC, Packed decimal and Also Endian data.
Kindly let me know how i can achieve this.
Thanks,
Deepa

Hi,
that doesn't make much sense.
1. in .NET a sttring consists of Unicode characters, nothing else.
2. in a database, data is stored in fields, having some type, such as NVARCHAR.
3. "packed decimal" needs details
4. AFAIK "Endian data" does not exist; multi-byte data (such as int or float) can be stored in big-endian or little-endian mode, where one is "natural" on a given system and the other isn't.
I suggest you provide:
1. a better explanation of what it is you want
2. two examples with available input data, and the corresponding output data you hope to get (use either all decimal, or better yet all hexadecimal).

Depak - I suggest you read the guidelines for forum posting. This looked like an interesting question right up till the last 2 sentences.

hey...i wrote for code snippet as giving suggession to this problem in descriptive manner may create confusion...i was looking for code just to get what exactly the solution provider want to say....and urgency is just to show how important and valuable is ur post...
dont mind it....if u have knowledge and want to share....the pls do....dont give such replys....

public interface IncDec<br />
{<br />
void Increment();<br />
void Decrement();<br />
}<br />
<br />
public class MyIncDec : IncDec<br />
{<br />
private int x;<br />
public MyIncDec(int x)<br />
{<br />
this.x = x;<br />
}<br />
public void Increment()<br />
{<br />
this.x++;<br />
}<br />
public void Decrement()<br />
{<br />
this.x--;<br />
}<br />
}
Part 1: Implement a class which can be used to measure how long each invocation of the Increment and Decrement method takes (in milliseconds) and prints out this information. The class should fit in more or less transparently with existing clients of the IncDec interface.
Part 2: Imagine you need to do something similar (timing of method calls) for many places in an application. What other ideas come to mind, e.g. could you propose other ideas for getting timing information more conveniently?
I got this question need to answer, it is simple, just something confused to me. hope anyone can help me.
btw, what "The class should fit in more or less transparently with existing clients of the IncDec interface.
" means?

I suppose your teacher (this is homework, right?) means to give you a hint. If you create a new class that inherits MyIncDec and call the base classes methods, you can use this class instead of the orignal and have a place to put your performance timing code without disturbing MyIncDec's existing users.
Standards are great! Everybody should have one!

its not homework, I konw its simple.
thanks your answer. do you think the new class inherit from interface or that class. which one is better

Hi,
this is a stupid assignment. In order to make it a realistic problem, one would need to measure a method containing hundred or more instructions to start with, not a single increment.
The code required to transparently measure the duration of an increment will probably use a derived class, virtual methods, and a StopWatch. As such it will be much slower than the original increment itself, so the result is bound to be inaccurate (on top of being utterly irrelevant).

Hi Guys,
How can we set the web browser control for example if the user load a .doc file on it then it cannot be edited? I mean, the user is not able to change file that has been loaded in the web control (example format is '.doc','.xls' etc..).
I'm trying to counter this kinda things, but sad to say, I did not find some hint or solution on how to do that.
Thank you!
regards,
erson

So far as I know, you must set a password for "Change Document" in word during saving. Wrong password means not able to edit the document.

Why are you posting in the C# forum then ?
This is a TON of work. You would need to basically write a framework that allows the user to create their own controls and databind them. I would say it's almost certainly beyond you.

hello...
i am developing a C# window based application.i have a form(view Item) that contain a datagridview and a button.
datagridview shows the item information and at the button click a new form(Add Item) opened by which user can add the item information.
All i need to do is after filling the item information when we click the save button the datagridview must be updated.
How can i do this.
