You need to check whether page is postback.
Put your database insertion code inside following condition.
if(!IsPostback)
{
}

i do that but the first time insertion in this case not done
|
|
|
|
|
Use a hidden field. Check the value of the field before you do the insert. If the field is blank, do the insert and set hidden field value to "inserted", else don't insert.
|
|
|
|
|
After saving the information in database simply redirect to the current page. For instance, if your page name is insert.aspx then after saving the record write :
Response.Redirect("insert.aspx");
This will prevent the page from raising postback on refresh.

Hello,
I am working on Classic Asp, using XMLDOM in javascript. This work perfectly with http , but when i try to use https, it throws error.
Please guide me, how can i solve this. Thanks.

|

I would start by learning how to ask a question. You could include the code that is not working for example. And instead of saying:
brijraj wrote: it throws error.
you could include the actual errormessage.

Hi,
Well i am getting Error below error using Microsoft.XMLDOM in javascript,
Interesting part is -- this working perfectly in http but not in https.
Error Number : -2146697208
Error Description : "The download of the specified resource has failed."
Thanks.

I am still missing the source of the script. You do not have to include the whole script, but if you include the lines where the error message occurs it could clarify things. So please include the source and tell us at which line the error occurs.

var source = new ActiveXObject("Microsoft.XMLDOM");
source.load(TargetUrl);
alert(source.parseError.errorCode);
alert(source.parseError.reason);
************in TargetUrl i am using asp page which return me xml.
Once source.load is done then i am getting error.
i am checking source.parseError.errorCode and source.parseError.reason to check error.
Thanks

And what happens if you open the TargerUrl in your webbrowser? does it return valid XML?
Wout Louwers

Yes, i had check the TargetUrl in https, it returns data.
But when i am using Microsof.XMLDOM, its not loading data.
Please guide me thanks.
|
|
|
|
|
could you also answer these questions?
The webpage fom which the javascript is run, dows it also use https?
Is the data valid XML?
What happens if you set validateOnParse to false?

I am not sure if I am asking this in the right forum or not, so feel free to direct me to another one if I am in the wrong place.
How do I make a file viewing application that embeds into Internet Explorer just like Adobe Reader and some other applications does? I know that it has something to do with ActiveX but despite spending an awful lot of time searching for information about it I have not found what I am looking for. There is a lot of information around about making ActiveX controls but that is not really the same thing if I have understood it right.
What I would like to build is a simple image viewing application with a few basic editing commands like rotate and so on. The application should have toolbars and drop down menus and last but not least: It should open up embedded into Internet Explorer. How do I accomplish this?

hi.
i m having problem with post back.
i m having my .vb file in which i got my edit button even sub and save btn event sub.
i m declaring ( dim flag as integer =-1 )on page load event. on clicking on edit button flag becomes 1
and in save btn event i got my condition
if flag=1 then
<my code="">
end if
when i hit edit flag becomes 1 and on clicking on save button, the button's postbck event is called and due to post back the flag is initialised to -1.
i know what is postback and how it works .but m not aware how to handle it..
can anyone help how to come out of this situation??

Methinks this seems like a contradiction.
|
|

Your page_load event will get called each time there is a postback. So when you click your save button it's setting your flag back to -1.
you should look at:
page.isPostBack

Hi,
I think I am trying to do something here that CSS doesn't allow, but would like to ask, anyway.
Just as CSS enables separation of style from content, I also like the idea that within CSS I could define a color table, and then use the names of those colors in the CSS styles applied to various DOM objects.
I've been studying the W3C CSS spec, consulting various CSS websites, but haven't found any way to do what I want : perhaps it's not possible ?
I have a nice color scheme cooked-up and exported using Petr Stanicek's great ColorSchemeDesigner site[^].
I can insert it into a CSS style sheet like so :
/* generated using http://colorschemedesigner.com/ */
.primary-1 { background-color: #956500 }
.primary-2 { background-color: #624D22 }
.primary-3 { background-color: #4D3400 }
.primary-4 { background-color: #AB7A12 }
.primary-5 { background-color: #AB7E20 }
.secondary-a-1 { background-color: #081865 }
.secondary-a-2 { background-color: #1A2143 }
.secondary-a-3 { background-color: #010A35 }
.secondary-a-4 { background-color: #172B86 }
.secondary-a-5 { background-color: #223386 }
.secondary-b-1 { background-color: #062763 }
.secondary-b-2 { background-color: #192741 }
.secondary-b-3 { background-color: #011333 }
.secondary-b-4 { background-color: #153C83 }
.secondary-b-5 { background-color: #1F4383 }
Where each color is now a "class."
But I can't use those class names as I thought I might :
a:link
{
color: silver;
background-color: .secondary-b-5;
}
a:link
{
color: silver;
background-color: secondary-b-5;
}
The above two examples will have no effect on link color. And I can't find any way to indicate that a:link should somehow "inherit" from the class ".secondary-b-5"
Is there any way to achieve the kind of abstraction I am trying for here ?
thanks, Bill

I have little knowledge about css class.
But you can try pseudo class of css.

If this one does not help you, I do not think there is any other way
to satisfy your requirement.

Thanks, Jinal, for your reply. I've gone through the CSS pseudo-classes, and, while there are many interesting things in there, I am afraid that addressing this issue is not implemented in any of them.

It may be that is is failing because it is being defined 'Inline'.

Hi Dave,
Thanks for your reply. Even if I put the "color-definition" classes in another CSS file, and load it on the page before the CSS file that attempts to use them, I'm afraid it won't make any difference.
I do think this is just not possible, and that CSS, by design, has no equivalent to a "named variable" which can be expressed in CSS, and then used by CSS.
I'm just lazy, and don't want to go through a bunch of HMTL sticking in "class='***' "
best, Bill

Hi Mark,
I've read your article; it's excellent, and I appreciate your response.
In this case I'm not working with ASP.NET. I am wondering if there is a way, in JavaScript, to dynamically modify CSS "objects."
But, on the whole, I think there is no practical way to "switch" color schemes using only CSS and JavaScript: if there were, then I would guess the "context-sensitive" code you'd have to write in the JavaScript would be a lot more trouble than going through html and doing search-and-replace on id's or class' declarations.

Andrew, an up and coming CSS/HTML JavaScript guru, at ITNewB[^], kindly responded to my sending him a link to this thread with the following comment :
... quoted with permission ... ITNewb is not a "commercial" site ...
"I do see the problem you're having. We can't assign a class to the property portion of an attribute. You can of course apply multiple classes to an element by doing class="class1 class2" and so forth.
Generally speaking, you're still going to have to assign a class to the anchors by one means or another. Sure, you could write big complex selectors but they're quite inefficient.
Try to keep your selectors to no more than two (eg- .box .anchor {}). CSS selectors are parsed from right to left, not left to right. As to how you get those classes applied to your actual anchor elements is up to you.
Also remember the vertical position of your classes matter. Generally, if class B is defined after class A, class B may overwrite properties in class A (such as color etc) which can be useful."
Andrew has some very good articles on things like doing transparent fades in JavaScript using cross-browser techniques[^], etc.
