Re: Data Binding Problems

16-Jan-04 13:01

Hi,

I have been using data binding for a lot of features and it is kind of working, but I keep getting into the chicken and the egg situation; I initialise the dataset in Page_Load, but, for example with a databound combo box, its selection resets when the page loads. This shouldn't happen because I have set the "AutoPostBack" property to true, if I temporily take out the dataset initialisation code then the combo box works fine, but of course with no data in it.

Would anybody be able to point me in the right direction please?

Regards,
Lea Hayes

maybe you need to use

if (!Page.IsPostBack) {
    // Initialize/databind combo box here
}

in your Page_Load

I've got a textbox in which I don't want the user to be able to use the backspace button. How can I cancel? I tried the event.cancelBubble but it doesn't seem to work.

Please help.

I can't see how cancelBubble would help you do this.

What would I do:
I would store the value of the text field in a variable, then, onChange I would compare the new value with the old one. With the correct logic I would return true or false and would allow the new value or replace it with the old one.

Hope that this helps.

Image/Image Button Controls

Re: Image/Image Button Controls

Hi,

When selecting an image (within the code) using: MyImage.ImageURL = "test.jpg", the image is stretched within the image control, is there a way to make the image control automatically change to the images size?

And another image related question, how can you obtain the images dimensions?

Don't specify a width or height in the IMG tag Smile | :)

I imagine the same way you would access the SRC attribute

document.blah.myImage.width

blah is not actually an object, you'll have to figure that out.

Does anybody know how to fill the fields of IE's web page
from within VB or C++ ? What if the page is secure? Of
course, there is no problem to fill all the fields by
hand. The question is how to do it automatically, by
running .exe or .dll.

Wrong forum Smile | :)

You mean like Google toolbar auto form fill feature?

It's generally more difficult then writting a normal EXE I suggest looking at the following article for a heads up:

http://www.codeproject.com/atl/ietoolbartutorial.asp?target=ie%7Ctoolbar[^]

I imagine you might be able to do it with a normal EXE, but you would have to tap into the IWebBrowser2 interface, so I hope your comfortable with COM interfaces Smile | :)

I think your in the wrong forum too Smile | :)

Anyways

innerHTML will replace all HTML inside the current element and outerHTML will replace all HTML inside the current element including itself.

So...

If you replace the innerHTML of the following DIV with nothing

<div>
<b>This is innerHTML</b>
<div/>

You get

<div>
nothing
<div/>

Whereas outerHTML would do the following

nothing

HTH

Re: The mighty QueryString

14-Jan-04 21:03

Hi,

I have just started with web development and seem to be doing okay. When a hyperlink is pressed on my webform I am adding different tags to the URL, i.e. "mypage?mytag" simply by adding it the the hyperlinks. When my page loads how can I obtain access to my tag, at the moment I am only interested in adding one tag at a time with a consistent length of characters.

Is there a way to obtain the URL stored in the address bar of internet explorer?

Any help would be greatly appreciated!

Lea Hayes

Yes, what you are looking for is info on the QueryString. That is the bit of info from the ? onwards and can contain multiple name/value pairs. e.g. ?var1=xyz&var2=123&var3=bob. That contains three pairs.

To access these you use the Request object and the QueryString class.

So to access the second pair in the above example you would use Request.QueryString("var2").ToString(). You can use the name of the variable which is nice instead of it's position.

Hi,

Thanks for your help, using Response.QueryString().ToString(), I am able to retrieve the text after the '?' symbol. However Request.QueryString("var2").ToString() gives me an error, looking at the syntax it doesn't seem like you are meant to place anything between the parenthesis. Do I need to include an external library to use the QueryString function with the "var2" or other variable name?
