Hmm, can you post a complete example to reproduce your problem? That way, I can debug it on my local computer and maybe give you some insight.
Until then, try this. Replace these:
dataGridView2.InvokeRequired
dataGridView2.Invoke
with these:
this.InvokeRequired
this.Invoke
Not sure that will work, but it's worth a try.
|
|
|
|
|
this.InvokeRequired<br />
this.Invoke doesn't work (i don't need invoke "this" object)
and about examp
give me your email, and i'll send it to you

I'm not going to give you my email address and I'm not going to run already compiled code. Create a simple example and paste the code here.

Hi codeproject World !
How can i convert string to decimal and remove unused Zero .
example :
string decimal = "192.0205000";
Decimal D = Decimal.Parse(decimal);
and wanna to have :
D = 192.0205
NOT D= 192.0205000
PLZ HELP !
|
|
|
|
|
And what is this code doing? Did even tried this?
|
|
|
|
|
Yes
it returns :
D= 192.0205000
BUT I wanna
<code>D= 192.0205 ====> Without unUsed Zeros</code>

Either strip the zeros off the string or use Math.Round

JYIS, they aren't there! They don't exist!
Edit: I posted that before I saw that you were using Decimal rather than Double.
ToString:
"
The return value is formatted with the general numeric format specifier ("G"), and the NumberFormatInfo object for the current culture.
"
G:
"
The exception to the preceding rule is if the number is a Decimal and the precision specifier is omitted. In that case, fixed-point notation is always used and trailing zeroes are preserved.

The trailing zeroes? Yes they do. See here.

|
|
|
|
decimal d= decimal.Parse("1120.00120000",System.Globalization.NumberStyles.AllowDecimalPoint);

Just a minor point - in numeric terms, 1120.00120000 is exactly the same as 1120.0012. If you're doing a calculation using a decimal then it doesn't make much sense to round trim it.

Indeed, though there is a difference in some situations, such as when using ToString(). Try running this:
string strD = "192.0205000";
Decimal D = Decimal.Parse(strD);
MessageBox.Show(D.ToString());
I never knew that the Decimal data type actually maintains the trailing zeroes.

Excellent question! And thanks for providing the answer. I had no idea the Decimal data type stores trailing zeroes.

Just a bit of friendly advice... avoid using uppercase when not necessary, don't beg for help, and don't shorten words (e.g., "PLZ") except for common acronyms. To many people here at Code Project, it appears unprofessional. Other than that, though, great question.
EDIT: It appears your answer is incorrect.

This is merely a quirk of the "G" format; when ToString ing a Decimal, use something along the lines of d.ToString ( "#.###############" ) .
|
|
|
|
|
Good call. One can also use:
d.ToString("G29");
|
|
|
|
|
That's basically what the default is and I don't think it works.
|
|
|
|
|
|

After reading what everybody has said, I think you want this:
Decimal d = Decimal.Parse(Decimal.Parse("192.0205000").ToString("G29"));

Hello!
I want to do some custom drawing on my windows forms application, which involves connecting my own defined controls with lines.
That should be easy, but I couldn't figure a way to draw these lines as objects/controls, so I can define events for them. I am also thinking of not getting too greedy with the memory.
I appreciate any suggestion.
Thank you!

This[^] might be a good beginning.

Here's a line control that I wrote. Real simple, and it has a LineClicked event.

I have a text box and a crystal report viewer in a windows form.
As user types in some text in text box, it should immediately display in report viewer. I have done this, but I have problem here, that is "If user types too quickly then refreshing of the preview screen is fine, but if user type slowly then text is lost"
I am not able to find a solution to this problem.
I tried with multithreading, with timer but could not able to implement it.
can someone please help me in this?
Thanks in advance
