Is it the TextMode.MultiLine property that you mean?
Standard question #2:
What error message do you get?
Standard question #3:
What does your code look like?

What is it that I should test?
The textbox itself doesn't have any problems with those characters, so it has to be some other part of your code that does. As you haven't shown any of your code, and haven't explained what the error is, or if there is an error message, I have no possibility to recreate the error or even tell where it might occur.
If you are using the value from the textbox in an SQL query without coding it correctly, that could explain the problem with the apostrophes, but not the problem with the quotes.

I used it normally, when type the tag like
and try to insert it into Ms Access, so I get error. I don't know how to do

What you should do, is to go back and read my first reply and answer the second and third question also. With the information you have given so far, I can only guess what the problem might be, and I have already done that.

I am dynamically creating a load of link buttons and adding them to the page as below
MyLB = New LinkButton <br />
MyLB.ID = "ObliLinkButton" & MyReader("ObligationID") <br />
MyLB.CommandArgument = MyReader("ObligationID") <br />
MyLB.CommandName = "DeleteMe" <br />
AddHandler MyLB.Command, AddressOf Me.DeleteBtn_Click <br />
MyLB.Text = "Delete" <br />
Obligationslbl.Controls.Add(MyLB)
The buttons all render as they should but when i click them they dont fire the code below
Protected Sub DeleteBtn_Click(ByVal s As Object, ByVal e As CommandEventArgs) <br />
<br />
Dim MyRecords As String = e.CommandArgument.ToString <br />
Response.Write("TheRecordIs" & MyRecords) <br />
<br />
End Sub

You should rebuild the items you have build dynamically after post back. Because of the stateless nature the page does not know that in the last cycle you created a button with an eventhandler. In the postback data there is written that button X fired an event, but since button X does not exist anymore after the postback (you did not rebuild it) it cannot handle that event.

well, you learn something new every day....
Thanks, its working now i have moved the code to load every time the page does. It means extra database hits but the trade off is worth it.

The thing is that the postback resets the page to it's original state, so any information regarding the dynamically created controls is lost. Why is that? Because the Page class is stateless. The Page recreates child controls based on the tags in the aspx files, so your controls not being present there are not shown. What you need to do is recreate the controls in the OnInit event or any event that fires before PageLoad, or in PageLoad if you do a check to see is the page is posted back. See this article[^] as an example.

Hello,
I have made a small project in asp 1.1 which selects the file from a directory and shows all images with the help of array and datalist. I was also able to make previous next button.
Now My problem is I want to make a auto slideshow, I don't have ajax. I don't have any idea of java too. Can any one kindly let me know how can i make it from an array of asp.net to javascript so that the slide show works. I preassume that can be done only in java.
Or is there any way I can do it in asp.net codes.
Can I also put a browse Button so that user can choose the directory he/she wants, as I am using a textbox to put the path from where it will pickup.
Sorry for my ignorance I am learing now, kindly help.
Thanks in advance

I will give you a couple of pointers:
If the directories are on the server, you have to build some server side control that loops over all the directories that you want the user to be able to print from, and print these to the screen.
When the user selects a directory, the server gets all the filenames from that directory and using a loop prints it into a javascript that looks for example like this:
var images = new Array(5);
images[0] = new Array('/images/','image1.jpg','Some description maybe');
images[1] = new Array('/images/','image2.jpg','Some description maybe');
images[2] = new Array('/images/','image3.jpg','Some description maybe');
images[3] = new Array('/images/','image4.jpg','Some description maybe');
images[4] = new Array('/images/','image5.jpg','Some description maybe');
So know on the client side you will have all the info to start working on your slideshow.
Now the missing element for the slideshow, is some sort of a timer, that is where the setTimeout() drops in. Once the user clicks start slideshow, he calls to a function that looks like this:
var isSlideshow = false;
function StartSlideShow()
{
isSlideshow = true;
ShowPicture (0)
}
function ShowPicture(picId)
{
if (isSlideshow) {
document.getElementById("img").src = images[i][0] + images[i][1];
setTimeout('ShowPicture(' + picId + 1 + ')',2000);
}
}
function StopSlideShow()
{
isSlideshow = false;
}
Here you should have all your ingredients to start on your slideshow.

let me first thank you for you help. I am sure I can do the slide show with your kind help. But I have one more question connected to it. I am using the codes below to get an save the path as well as the file name in asp.net code
For Each s in directory.GetFiles(textbox.text.trim, "*.jpeg")
How can i make the same type of array for the path and file in java.
Thanks alot again.

I guess you mean javascript? Look if the folders you want to browse through are on the client side, you'll have a problem, since the browser is not allowed to do things like folder browsing etc (think of the security issues that would rise with such a feature). So then indeed you need to use Java to make a small applet that would browse folders on the harddrive. I'm not a Java expert, so I don't really know.
If we talk about folders on the server, then you indeed have to loop on the serverside through all the folder and print them to the client in HTML.

You can't put images in to SQL Server using ASP.NET.
ASP.NET is a technology for writing web applications. It simply does not deal with the database. If you want to do anything with the database you must use ADO.NET.

This is for ASP.NET 1.1 but should be easy to convert to 2.0. The stored proc inserts the file into a blob/image field in the table.

I'm trying to open a server side MS-Word document and present it client side. I just want the word document to appear inside the browser or open up for viewing. When I run the code I'm prompted to "Open" or "Save" the file. If I "Save" the file it is the file that I requested but if I "Open" I get the following error: "This file could not be found. Try one or more of the following: * Check the spelling of the name of the document. * Try a different file name."
Code:
Dim _webClient As New System.Net.WebClient
Dim sURI aAs String = "file://C:\test.doc"
Dim theBuffer As Byte() = _webClient.DownloadData(sURI)
With Page.Response
.ClearContent()
.ContentType = "application/msword"
.AddHeader("content-disposition", "attachement;filename=test.doc")
.OutputStream.Write(theBuffer, 0, theBuffer.Length)
.End
End With
_webClient.Dispose()

Where is the document stored?
If it's stored on the client computer, you can't load it that way. The file that you are trying to get with the DownloadData call is located on the server.
bgates1970 wrote: If I "Save" the file it is the file that I requested
Have you verified the contents of the file that you saved? I think that you will find that it's not at all the document that you have saved, but the error message.

The file I'm trying to load is located on the server (Windows 2003 SP1). I have verified that the file that I "saved" is indeed the same file.

Why on earth are you using a web request to open a file on the same server, then? Use the IO.File class to open it.
