hello,
I am creating a data visualization tool using C# and Javascript. I have embedded a webbrowser control in a C# winform application and have written a javascript code for it.
My problem is i need to pass a value from javascript to C#. I am successfully able to pass value from C# to Javascript but not vice-versa.
my javascript code is
google.maps.event.addListener(marker, 'dragend', function(ev){
var newpos= marker.getPosition();
});
i want to pass value of newpos to C# so that i can use it for further computation
please help me for this.

yes, it can be a bitch. What you can do is add a server control (label, textbox, ...) and hide it. You can assign a clientid to that control. That client id is known by javascript. In fact, you can just assign it a server id and load the page. If you search the control in your webpage source you'll find that .net created a client id for you (mostly the server id with an autogenerated suffix like c001 or something).
hope this helps.

I am using WCF services with Thread Pool concepts in the application using Oracle Database. The application has a Scheduling Workflow, where there will be multiple Jobs scheduled at the same time. The expected behavior is that, once the scheduler is triggered, all the jobs should be started parallel and at the background, various process are run.
All the jobs are not started in parallel. Say for example, if there are 20 jobs scheduled, only 15 are getting started and remaining are struck.
It results in Oracle Connection request timed out error.
Options Tried:
As the application uses PerSession and Concurrency mode as Multiple. Tried this could have been a WCF Throttling issues. So modified the Throttling parameters as well. But still results in Oracle error.
Any help would be appreciated.

pls help wiht this code
int intOrder = int.Parse(frmInput.InvoiceOrder);
byte[] photo_aray;
OleDbDataAdapter adapter = new OleDbDataAdapter("select photo from cards where id= " + intOrder, strCon);
DataSet ds = new DataSet();
adapter.Fill(ds, "cards");
// ds.Tables[0].Constraints.Add("pk_sno", ds.Tables[0].Columns[0], true);
picBox1.Image = null;
if (ds.Tables[0].Rows[rno][6] != System.DBNull.Value)
{
photo_aray = (byte[])ds.Tables[0].Rows[rno][6];
MemoryStream ms = new MemoryStream(photo_aray);
picBox1.Image = Image.FromStream(ms);
}
}
image not showing in picbox

Have you used your debugger to step through this code and check that all your variables are correctly loaded with the information that you have in the database, and that the picturebox image is a real image?
One of these days I'm going to think of a really clever signature.

Richard's right. Add a breakpoint on the if statement. To do this, you can click on the line and press F9 (this is the shortcut to toggle the breakpoint on and off). You should see a red dot appear in the gutter in Visual Studio. Press F5 to run your application. When you hit the if statement, press F10 to step over the code. If you do this you will find out if this value is null or not.
Now, one thing I would do is wrap the MemoryStream in a using statement. A MemoryStream is a disposable object, so you should always dispose of it. This would give you:
using (MemoryStream ms = new MemoryStream(photo_array))
{
picBox1.Image = Image.FromStream(ms);
}Your code will now dispose of the stream.

Hi
I want to load a bitmap do some changes on the pixels and save it as new bitmap with a new name.
Will it work if I'll use the save method of the bitmap class (I'll give it as a parameter the path with the name "C:\\NewBitmap.bmp" for example, or is there another method for doing it?
thanks.

I can't see why not.

Yes - the Save method is the one to use.
Two things to note though:
1) Don't try to save it to the root directory - Vista and above won't let you write to the root of the boot drive to help prevent virus and trojan attacks - use a different directory unless you app has admin privileges.
2) Be careful what format you save the image in: many types including JPG are lossy compression, so each time you save and open it you will get a fuzzier, less detailed image. Use BMP or similar for working images, and JPG for final presentation only.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

Fascinating. Thanks for sharing.

That's bad news.
Perhaps if you shared what you've done, with relevant source code on, say, a site targeted at c# developers, they'd be able to help you

The quality of the question you ask directly dictates the quality of the answer you get.
Your question was so bad that the only possible answers were sarcasm. in other words, your question was nothing but a jumble of random words.

Are you and the guy below a) The same person or b) in the same class?

might be in the same batch doing the final sem project  looks like they have communication problem that needs to be resolved first before they find answers for the other problems

Yes, all you need do is hire someone to write it for you.

Open your question and have a look at it.
Here's what I, the idiot on the other side of planet, see when I read this question.
- descriptive subject of the topic "hi". Yup, this tells me EXACTLY what I need to know about your question. (figuratively it actually does)
- C# contents of the question considering we're in the C# forum. None.
- Actual coding question. "can i get coding". Answer: Somehow you probably can, the sky is the limit.
- "segmenting overlapped and touching chromosomes" reads as "dkjsgfgf dkjsghfdaskjgfaskdsvf dhgfwkevfwvfkev ewkrhvewk" to me or it could be Klingon, or Ferengi or something else. How should anyone with a normal background in IT know what this is about? it is not unuseful, but it doesn't help in this case, add more context.
- "using hierarchical distributed genetic algorithm for image segmentation" what is this? Can YOU answer this question? My first thought, if I would need this, is to google it and see if I can get some more information. Then I would be able to clarify this to the people I'm asking questions to.
Your question seems to state you want a complete answer and solution to the problem. Wrong forum. Here we try to help people who get stuck with a specific problem they encountered and researched and tried to resolve themselves.
Do some research, get started and come back if you have more information.
