First you will need to catch textbox2 enter event. In that event you can change input language. Then set input language using InputLanguage Class

First, you have asked this question before. Second, this forum is for people who are having issues with existing code. Asking someone to just hand over the code so you don't have to work on it is considered RUDE.

No one is going to give you complete code here. I gave you directions and you can explore them. If you are stuck at a specific point please say so and I'll be happy to help you Smile | :)

do you want to enter english in tb1 and enter arabic in tb2, or enter english in tb1 and have it translated into arabic and displayed in tb2? The existing answer will let you do the former, the latter will require buying 3rd party translation software. I have no recommendation for this.

Hi,
I have the following code to upload one file.

private void cmdUpload_Click(object sender, System.EventArgs e)
{
if (( File1.PostedFile != null) && (File1.PostedFile.ContentLength > 0))
{
//determine file name
string sFileName = System.IO.Path.GetFileName(File1.PostedFile.FileName);
try
{
if (File1.PostedFile.ContentLength <= lMaxFileSize)
{
//Save File on disk
File1.PostedFile.SaveAs(sFileDir + sFileName);
lblMessage.Visible=true;
lblMessage.Text="File: " + sFileDir + sFileName + " Uploaded Successfully";
}
else //reject file
{
lblMessage.Visible=true;
lblMessage.Text="File Size if Over the Limit of " + lMaxFileSize ;
}
}
catch(Exception)//in case of an error
{
lblMessage.Visible = true;
lblMessage.Text="An Error Occured. Please Try Again!";
DeleteFile(sFileDir + sFileName);
}
}
}

I want to upload two files intead of one.

Please help.

I have a mulitline text file that has repetitive info in the first 29 characters.

My program will strip the extra garbage off from each line and append it to the previous line.
It also will change the color on specific lines of text, at a specific position, and it opens into a RichTextBox.

I would like to speed this up somehow. Depending on the size of the file it takes a long time. I want to be able to apply the formatting etc while the file is in a buffer I guess, and then display to the RichTextBox.

Thanks,

Modifying an existing file

Hi
well I have an XML file and an XSL file to transform that. I want to show the XML file in the webbrowser control having the transformation on using the XSL file. As most of u must be knowing that we need to add a statement such as the one given in bold after the <xml> tag.

<?xml version="1.0" encoding="utf-8"?>
<b><?xml-stylesheet type="text/xsl" href="c:\xmlDefaultStyleSheet2.xsl"?></b>

Is there some way so that I can just write that portion to my xml file and show it in the browser (modifying the file) so that I dont have to write a new xml file altogether?

Thanks in advance

Rocky

No. But there is a way you can keep from re-writing the xml source file, by performing the transformation yourself and load the results in the browser.

OK so can u give me an example for that...

Yea I think I get the idea now Mike... its about using XslTransform Function right

Rocky#15-Aug-07 18:59

There's still a small problem.. The example is given like this

//Create a new XslTransform object.<br />
XslTransform xslt = new XslTransform();<br />
<br />
//Load the stylesheet.<br />
xslt.Load("http://server/favorite.xsl");<br />
<br />
//Create a new XPathDocument and load the XML data to be transformed.<br />
XPathDocument mydata = new XPathDocument("inputdata.xml");<br />
<br />
//Create an XmlTextWriter which outputs to the console.<br />
XmlWriter writer = new XmlTextWriter(Console.Out);<br />
<br />
//Transform the data and send the output to the console.<br />
xslt.Transform(mydata,null,writer, null);<br />
<br />

The XmlWriter is throwing its output on the console but how can i throw the output on my webbrowser control w/o making a new file? the transormation doesnt create HTML it only chnges the way XML is diaplayed. infact it just collapses all the nodes

Hey Rocky, glad to see things are progressing. Before we move on to the next problem I would take a moment to note that your original post was rather vague on this second problem. Strict interpretation of it notes that you didn't want to re-write your XML "Source" file. The solution we discussed solves "that" problem.

Next make sure that writing the transformation output to disk actually is a problem and if it is then you can use the WebBrowser.Document property to access the HtmlDocument object which has a Write(...) method.

However, my experience doing that with complex javascript in the resulting HTML tells me that some odd behavior can occur using this approach. I don't remember the details but in one instance I had to accept the limitations presented at the DHTML level while in another instance I had to adopt a temporary file solution that wrote the transformation to disk.

Hope that helps

u know what you're absolutely right!! I wasnt very clear in my mind myself Smile | :)

<blockquote class="FQ"><div class="FQA">led mike wrote:</div>The solution we discussed solves "that" problem</blockquote>

well I'm not so sure abt that. Bcz when i tried to make a new file I adds those <HTML> and some other 'unwanted' tags from HTML and the resultant output is not what I want. The problem is that when i add the refrence to my XSL file in the XML file and then open it in IE it shows the thing I want to see that is all nodes collapsed but when i try to put the transformation on the same XML file (without the reference to xsl file) it gets all messed up bcz of the added HTML tags in the new file made.

The XML files in my case can be very large in size I thinkits size can go into MBs as well so that was the reason I was trying to avoid this rewriting of file.

Actually to be honest I'm totally agaisnt this idea of showing an XML file in WebBrowser Control bcz large XML file can take forever to open up and I dont think there's any way in the world tat we can put some kind of transformation (like collapse all nodes) on without having to refresh the file and open it again + there is alot of chance of having to rewrite it again and offcourse that would be disastrous. I'm the junior most person in the team so who listens to a guy like me Frown | :(

Hope I got it quiet clear this time

Thanks for ur help

Rocky

Then modify the XSLT to output "exactly" the HTML that you desire. Or I don't understand what you are saying.

This is the first I am hearing about "collapse all nodes". Is this one of your requirements? When you post a question on a forum like this and leave out critical requirements you might get answers that take you down the wrong path. This may be one of those instances.
