You want to split hte data between two datasets ? Did you have a use for the full dataset as well, or would you be best to handle this by getting the two sets from your data source in the first place?

Nope. I'm pretty sure that there are stupid questions. My wife keeps me well informed when she thinks I hit the mark.

I'm using XP and I can't search eventlogs for a specific string like vista.
is there any tool to do that?
|
|
|
|

From Eventviewer -> View -> Filter, you can filter Data.
If you want search String, you can create your custome Tool. and i thing that you can do with some Effort.

 hello does someone know how to put a code in one of the treeview nodes???
i want every nodes to open differennt window forms..
how can i do it??
please some sample codes.. i really appreciate it,
ginji

|

Well, I assume the nodes have a tag property. You could set that, handle the selected node changed event, check the tag and based on that, open a form.

hi ginji
do not Cry too much its not good for ur health and it never make you a good developer.
check the tree node events there is event call on node click in this event
<br />
<br />
if(e.Node ==Name of the Node)<br />
{<br />
Form2 obj = new Form2();<br />
obj.Show();<br />
<br />
}<br />

i want the flag true in if condition c the if condition and c the comments plz thx
just put a button on form and past those methods

I am at a loss to understand what you're asking. Which bit of code do you have a problem with ?
If the mail address and code are long enough, then the input to the program determines if it's true or not. We can't make it true in code, without short circuiting the logic that checks if it should be true.

how to do short circuit. i just want those parameters which can make if condition true is it posible please help me!
like if i send parameters (myemail@yahoo.com,abc123); if this makes the if condition true then i need these parameters how it posible or which parameters should i send which make the if condition true thx
its me yami
now cheers
Reply to the forums, don't email me.
Did you not write this code ? I'm assuming now that you've used reflection to read the registration code for a piece of software you want to steal, and you can't work out how to reverse engineer this process to do it.
If you wrote the code, then you should know how to create codes that work with it.

Wow.
I assume your datagrid does not display this way on the form, right ?

What do you think this will do ? I'm suspecting it will create a new row to be printed for every row in your data set. So, it sounds like you want to change i++ to i+=2, read two rows every time, and draw them next to each other.

i gave i++ to 1+=2
but i am getting only 1st row and 3rd row .. and the 2nd row and 4th rows are not coming..
i need all the rows while printing like below
Printed out should be like
Pepsi 500ml £1.09 coke 500ml £1.09
Fanta 500ml £1.09 Sprite 500ml .99p

Like I said, you plain do not understand your own code.
As I said, going to i+=2 means that you're not starting a new row for every item. Now you need to add code to draw every second item on the same row, or you will plainly get every second item only printed.

Hi,
Can you please refer me to a website where I can follow an asp.net 3.5 case study from start to finish?
I have searched msdn but have not found anything yet.
Thanks

Wondering if anyone has a state machine diagram on how regular expressions accomplish there job?
This way i can trace the diagram given a pattern and string input.
Regex.IsMatch
Regex.Replace
Regex.Split
just for learning purposes since i want to move deeper into interpretors and compilers. I already know how to implement regex in practice.

The book 'mastering Regular Expressions' from O Reilly has big chapters on how it all works internally.

Hi, I am new to c#, but I am a vb.net programmer. I have a line
strLastServer = drowData["ServerName"].ToString;
where strLastServer is declared
string strLastServer = "";
I am getting an error on build:
Cannot convert method group 'ToString' to non-delegate type 'string'. Did you intend to invoke the method?
I looked at an article on this site which seemed to suggest what I was doing was OK, but....
What am I doing wrong?
|
|
|
|
|
In C# method calls should have parathesis/()...
You will get used to it very soon 
strLastServer = drowData["ServerName"].ToString();
