Hi Buddies,
I think this quest will confus you. Wht i wanna to do is tht, I have develop 1 application in C# which can programaticallygenerating one Class file(say class1.cs) in C:\.
class1.cs will contain one method which include nos. of exe path which would be invoke one by one after calling this method.
In clicking on button I have to compile this file(class1.cs) automatically. If there is any error, redirect it to one text file else create one instant of class1.cs and then call the method.
Problem is
"how to create whole C# project programatically" and
"how to compile this .cs file programatically".
Help wud b appreciated.

I don't think that you can create whole C# project programatically. But you can create a C# file ( cs ) since it is a normal text file. Use FileStream to create the file.

Are you familiar with compiling C# file from command file. ? If yes you can write a bat file which contains these commands and execute the bat file. But regarding Identifying error and coming back to C# file, I don't have much idea.

You can do it using CSharpCodeProvider class. This article describes how to do it: Mp3ToExe[^]

Hi all
I posted this question yesterday also and no one replied me. I think no one is willing to help me or angry with me......
I want to read a particular node of xml file. For that i am using the code
XmlTextReader reader = new XmlTextReader ("tx1.xml");
while (reader.Read ())
{
if(reader.IsStartElement ())
{
if (reader.NodeType == XmlNodeType.Element && reader.Name == "jid")
{
str=reader.ReadString();
Lblmsg.Visible=true;
Lblmsg.Text="journal ID <"+ reader.Name+ "> is : "+str;
reader.Read();
break;
}
break;
}
}
but here the problem is it is trying to validate the xml file using the DTD. I dont want to validate it using dtd. Plz help to solve this. what i have to use here. Plz help me thank u

Why are you using an XmlReader? You could load the document into an XmlDocument object and then use XPath queries and SelectSingleNode or SelectNodes calls to get the node you are interested in.
|
|
|
|
|
Scott is absolutely correct.
XPath is fastest among all in parsing xml node.

YES he is. But if the XML file is pretty huge, then this method may take some time. I think XMLDocument class loads the entire XML file to the memory when it initializes. Am I right ?
|
|
|
|

Yes, you are correct. The XmlDocument class does read the entire file into memory. In my opinion, if you're trying to deal with XML files that large, you should probably be using something other than XML.
|
|
|
|
|
ya, u r correct? but buddy loading xml and parsing both are completely different. Its work of different object. Its just lik this Building apartement is made by engineer, but its maintainance is depend on people who live ther.
So, XPath is very fastest in parsing.

I want to read a huge xml file and the node that i want to read is about to the middle of the file. Then also XPath is of to use?

Why don't you write an application that compares performance difference for both the methods. I feel loading huge XML file to XMlDocument class will be slow compared to other.
|
|
|
|

Yes, XPath would be of use. XPath is the "query" language that allows you to retrieve a specific node or list of nodes. Think of it as working in a similar way to a SQL Select statement for a database.

What is the size of your xml file ? if its 1 GB like that then you hsould use xmlreader and dom in hand like this

Graphical problems really, functionality is fine.
Due to the slightly odd shape of the form, when you minimize / restore the form the blue (silver/green) bar reapears and looks kinda lame (WinXP). On minimizing i can just hide the form, minimize it, then show it again. But that code is in my little minimize button. When restoring i can't control what happens, so any ideas there would be great.
A more serious problem, when loading (initially and when restoring the window) everything appears, then all controls / graphics dissapear leaving a black shape, then all reappear. All withing a fraction of a second of course, i need to find out how to hide the form until everything has been (re)loaded then show it again. Also when the form first loads and it flickers, you just see garbage from the vram instead of the background image of the form, just for a fraction of a second of course.
Ugh anyway...
perhaps if you could have some kind of double buffering. I know c# has an option for that somewhere, but i don't know what it affects or how to use it. Argh, this is doing my head in.

Eew, temporary fix. On form load, set opacity to 0.
In the on paint event count up the number of controls draw (14 need to be drawn, so each time the paint event is fired by each control a counter is increased) once the counter reaches the required number the opcaity is set back to 1.0.
When you minimize the counter is reset.
It wouldn't be so bad, but not all controls set off the paint event, so i coulnd't compare the counter to this.Controls.Count

I think this might fix your problem if your form is extended from the System.Windows.Forms.Form class. Enter the following code into the constructor of your form.
<br />
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);<br />
I hope it fixes your problem, if it doesn't maybe someone else knows how to fix it.

Hi,
we may need more info, possibly code too.
Are you accessing some Controls from different threads? (you shouldn't)
if so, is this .NET 1.x? or have you set Control.CheckForIllegalCrossThreadCalls false
(you shouldn't).

I'm a Newbee, so be patient please.
My c# Application has a Tabbed control in it. (lets say 2 tabs just as an example, TabTest1 & TabTest2)
Each Tab has WebBrowser dropped into it and its default website is set to our test webserver.
If I log in to the webserver using the browser on TabTest1 using Testaccount1 userid and password all is fine. As soon as I switch to TabTest2 and log in using Testaccount2 userid and password, I find myself inside the Testaccount1's profile.
I guess I need to make these two WebBrowser components truly independent of each other, they appear to be sharing cookies & session variables.
I cant figure out how to do that.
(I can post the code if that will help)
I downloaded a couple of multiTabbed browser applications as examples from here and they exhibited the same behaviour.
I guess I am asking is there a way to make these WebBrowser Instances completely seperate within the same application.
(the hardest thing is explaining myself)

This doesn't have anything to do with the WebBrowser control. The website uses cookies, which are essentially tied to the site not the browser. Since each control is navigating to the same site, they are using the same set of cookies. In order to make this work you would need to change the web site to somehow create a unique cookie for each login.

I agree that the webbrowser controls are using the same set of cookies.
They are being tied to the application, which contains two browser controls.
I noticed that firefox's multitabbed browser displays the same traits (Shared cookies across tabs).
However...
If I launch IE point it at my test server, sign in (cookies are created). Then launch another seperate IE window point it at my test server this second window does not share the same cookies and behaves like a seperated browser(application) a unique instance. and I can log in with the different userid, and all is fine. (firefox does'nt behave the same multiple windows still share cookies)
I'm trying to achieve this behavior, of completely seperate browser instances within the same tabbed application. (I'm using IE version 6 by the way)
I guess i'm trying to achieve the impossible?
Thanks for the input Scott.

You might want to do the same test using IE 7 and see how it behaves.
You could possibly achieve this by loading different .NET AppDomains for each browser control, but that may not be worth the additional hassle of doing so.

Hi all,
I have written a small application that takes a snapshot of a webcam stream every so many seconds, and then saves as either a jpeg or bitmap.
Is there a straight forward way to convert these into a video file, such as an avi or mpeg?
Thanks,
Ben.
