Morning all.
Im currently working on a booking form and need to get the user to input, into two ASP textboxes, the date they want to arrive and the date they want to depart. To make it easier for the user when they click on the textbox an asp:calendar control appears. The calendar is hidden using css and the onfocus feature of the textbox is used to make it visible again. The javascript performs this by editing the calendars css display attribute.
The user can then select a date and the date gets thrown into the textbox. So thats all gravy.
The problem appears when the month selector is clicked on the calendar control, because of course this reloads the page and thus sets the calendars css back to it's original setting. Thus hiding the calendar control.
How can I get around this? Is there a better way of doing this.
My only other option is to have a link to the side of the textbox and reveal the calendar on that being clicked. But id rather use the onfocus event of the textbox and keep the form simpler...
Any help on this would be spot on. Thanks

Personally, my favorite way to popup a helpful calendar is to open a new window using javascript. This new window has JUST the calendar and the name of the textbox that it needs to set a value for is passed in the url. Then, to set up the calendar to update that textbox on the other window I add this code:
Note: calPicker is my Calendar control
Protected Sub calPicker_DayRender(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DayRenderEventArgs) Handles calPicker.DayRender
' Clear the link from this day
e.Cell.Controls.Clear()
' Add the custom link
Dim Link As New HyperLink
Link.Text = e.Day.Date.Day
'Format colors
If e.Day.IsOtherMonth Then
Link.ForeColor = Drawing.Color.DimGray
Else
Link.ForeColor = Drawing.Color.Black
End If
Link.ToolTip = e.Day.Date.ToString("MMMM d, yyyy")
'Tell the link which control on the other window to update
Link.Attributes.Add("href", "JavaScript:window.opener.document." & Request.QueryString("field") & ".value = '" & e.Day.Date.ToString("yyyyMMdd") & "'; window.close();")
e.Cell.Controls.Add(Link)
End Sub
You can still do it your way if you want, you will just have to setup a bunch of flag variables to check and see if you are supposed to hide the css or not, and you can also use hidden fields on the aspx side, and javascript.
Hope this helps.

Hi All! I want to get some link regarding accessing MS Word (through automation ) from javascript.(just like vb6 or vbscript allows). I need javascript as it is supported by all major browsers.
Thanks

can any one suggest why?
Thanx in advance

Well,
due to the fact that i'm not fascinated on tables like others are, i can only give you some simple hints.
But before that, i want to ask, why are you still using nested tables? It isn't even a rumour anymore, that it produces more problems and a massive code-overhead and eats RAM-Ressources 'til the earth stands still. Okay, whatever; Should be your problem, but if there's a reason why, please note it.
1) Even in html 4 it is not allowed to use style-attributes in every table-element when using nested tables, because without a class-definition in a cascading style sheet the doubled definitions are differently interpreted. That is, because tables are organized as a list inside the interpreter, so the normal 'The same tag inside (with a style definition) overrides the parent tag, is not given.
2) The 'td'-tags/-Elements that are emepty are written like '<td ></td>'. That space in between the opening tag should be deleted. Why? Because there are many browsers especially Mozilla-based and the older Netscapes that produce blank childs/doubled text-nodes inside the Element-Hierarchy while parsing the site on load. The result is unpredictable, because even the same browser-installation (same version, setup-type, etc.) is making it's behaviour dependent on the machines power (RAM, CPU-TYPE,etc.) and especially, the core-services provided by the operating system.
So just clean up that table-tree of those spaces. Anytime, you are building a site. There should be no element that hasn't attributes in it having spaces!
3) Due to the talk, any helper might give advice based on looking up the code-result in front-page... I'm not one of those 'pro-anything-else-than-microsoft'-users, but to be true, though' i'm loving microsoft-products i never used frontpage. But what i can tell you, is that the Internet Explorer (any Version) got a problem with '100%' of width in the style-attribute of a table. This is because the styles that are pre-defined for tables use borders, column-spacing and margin-settings, that make it impossible to run a table at '100%' width without defining a stylesheet that cleans up those pre-definitions.
In some tasks it could help to set the body-Element and all-Elements to zero padding and margin.
So the resulting code should look like:
(somewhere inside the <head>...
<style type="text/css">
<!--
body{
margin:0px;
padding:0px;
width:100%;
overflow:auto;
}
*{
margin:0px;
padding:0px;
}
//-->
</style>
This is the absolute minimum set of style definitions you might have to use if you want to use tables (especially nested ones) and are ready to style up any element directly per style-attributes.
4) It is definately unnessecary to double the styles, means: use per style-definition given width- and border-values OR use the direct formatting per attribute. Why? Because any browser-type has another way of processing those values. As the Internet Explorer until Version 5.5 is first rendering the site using the direct attributes (e.g.: width="100%", border="0") and then processes the style-definitions in your head-area, then adding external stylesheets and then at least looks up if a style-attribute is present inside the Element, Other browsers do it the other way around.
5) I didn't looked it all up, but check if you gave all values for width and border-width, etc. a px after the number, because some browsers don't recognize these values as pixel values if not set, instead using pt (Point ...typographic measure).
6) If you're not giving a doctype and/or a namespace definition, any browser will parse the code as html 3/4, but there you got a problem, because those who are using html 3 or html 3 compatibility don't recognize the %-sign in the width-attribute. Even the newest IE's and Safari, Konqueror and Co. partly don't recognize them because of the downward-compatibility and different table-handling.
So at least you should give a doctype. Look up http://www.w3.org and search for doctype headers.
If you don't know what this is, here is an example for a XHTML 1 Transitional DocType:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
The DocType in any case has to be the first line(s) in your html-file if you want to use it.
The according namespace to this (used in newer browsers, capable of XML-presenting) is:
<html xmlns="http://www.w3.org/1999/xhtml">
So this one is used instead the typical '<html>'-Element.
Well, i really don't know if any of this might have had helped you if you're through with practicing it, but maybe?
Just try it, take your time.
If you got special questions you're free to send me an e-Mail. Please be specific and precisely as you're able if you're asking for help.
You know, code is poetry, fine and tasty; ...but taste sometimes isn't discussable.
You're Welcome,

Hi,
Thanks for your reply. I am using Nested DataGrid in one of my page. and the output of that datagrid is nested tables when it renders the nested datagrid. I removed all the style from the table but still it is not showing me the 14th level. I noticed one more thing that if I remove top table i.e. root table then it shows me the 14th level. That means it just shows me 12 levels only. So, is their any limit for nested tables. I google this problem but i found that their is no limit for nesting the tables. Then why it shows only 12 nested table. I have given an example of frontpage for all to see the design view as well as preivew. In design view it's showing me all the levels but when I preview that page it shows levels till 13. I also see that output in browser (Internet Explorer).
When that perticular page is displayed to the user, user can see only 12 levels but in view source of that page their are more levels.
Is this is a limit of table or any drawback of html when it displays the output in browser?
Please suggest.
|
|
|
|
|
What should be the final view/look of that piece of structure?
Means: In which way you want to use it?
Which browser(s) and version(s) do you use (exactly) to look the results up?
Do you have the page online?
Is there a reason that binds you to realize the structure with nested-tables?
|
|
|
|
|
That page is not online now.
I am Using Internet Explorer 6.0 with service pack 1.
The sturcture is something like tree view. User can drill down to the Parent To Child. User can expand and collapse the records so I need to use the nested datagrid which finally render the nested table. The posted code is part of html output of that page. You can view that output if you want me to mail that html to you then i'll mail to you.

firefox doesn't use fireEvent.
and i want to fire an event when the value of the text changed, and when firing the event i should pass the key that has been press or the event it self?

Greetings all!
I'm quite new to javascript so i may have some rather silly kind of questions... but anyway here's the problem...
I want to loop through all the elements in a form so as to check their values in order to validate the relevant fields, i thought i could get the number of form objects within the form using "formName.length." Then use a loop to go through all the form fields.
It seems formName.length is not working for me ... it's returning "undefined" or "0" values. How could i get the number of form objects within a certain form.
My code is as follows:
[CODE]
window.moveTo(100,100);
window.resizeTo(300,460);
//window.locationbar.visible=false;
//window.menubar.visible=false;
//window.personalbar.visible=false;
//window.scrollbars.visible=false;
//window.statusbar.visible=false;
//window.toolbar.visible=false;
//window.resize=false;
//window.resizeable=no;
var elementNo;
elementNo = document.registrationForm.length;
//elementNo = document.registrationForm.txtFirstName.value;
var num;
num = document.forms[0].length;
var counter = 0;
var myMessage = "Please ensure that you have filled in the following fields:\n";
var myFieldsAlert = "";
var myAlertFlag="0";
function validate(){
//
alert("abc "+elementNo);
alert("abc "+num);
/**/
while(counter<elementNo){
//
if(registrationForm.elements[counter].value==""){
myFieldsAlert += "-"+registrationForm.elements[counter].id+"\n";
myAlertFlag="1";
}
if(registrationForm.optGenderM.value!="0" || registrationForm.optGenderF.value!="1"){
myFieldsAlert += "-Gender\n";
myAlertFlag="1";
}
counter++;
}
/**/
/**/
if(myAlertFlag=="1"){
alert(myMessaage+myFieldsAlert);
}
else{
registrationForm.submit();
}
myAlertFlag ="0";
/**/
return false;
}
[/CODE]
Could someone please enlighten me on the issue at hand and propose a solution. (By the way the code is in a HTML page which is called up as a popup).
Any help would be greatly appreciated...

Hi
I am using COM object in Web Application. There is a problem to solve authentication & authorization issue for Server site. At the time of using the COM object it shows the error " ACCESS DENIED ". If I am writing <identity impersonate="true"> in web.config, it is OK but the AJAX file is not accessible for that reason.
if I am using iisreset in Run command, then the whole application is OK, but it is not possible to reset iis again and again in production server. Have you any idea for this?
For more clarification, suppose there is a link in a Web page interface. After click the link, one Word document will open. How we solve authentication/authorization issue in iis without affecting to other files like AJAX.
I am using ASP.NET with C#. I am not using MTS.
any idea, please write.

Hi all friend,
I want to retrieve data as image from access database. I stored some image into access database. This field's datatype is OLE Object. When i want to read, convert stream, and write bitmap, i get some error.
1)OleDbDal.Images objImages = new OleDbDal.Images();
2)DataTable dt = objImages.GetImage(Convert.ToInt32(iId));
3)byte[] buffer = (byte[])dt.Rows[0]["Image"];
4)System.IO.MemoryStream objMemStream = System.IO.MemoryStream(buffer, true);
5)objMemStream.Write(buffer, 0, buffer.Length);
6)Bitmap objBitmap = (Bitmap)Bitmap.FromStream(objMemStream, true);
7)objBitmap.Save(Response.OutputStream,System.Drawing.Imaging.ImageFormat.Gif);
Line 1 to 5 is OK. Line 6 has error found. Error message is "Invalid parameter". If you have solution, could you help me.
Thanks.

I don't have any answer to your question but I would like to know why you are performing such a task. To store images directly in a Access database is not the best thing to do, especially if you plan to have any volume of users on the system. A hundred images in the DB and it will slow right down...
A better plan would be to save the files into a directory and reference their wherabouts in the database. You would be able to build pages with the images in a much similar way as you would do if you had saved them in the database.
The benefits of this would be:
Quicker database with less data stored in it.
Quicker to get the images when needed. Because you dont have to process the binary code.
The only thing you might lose is security, because they could simply be accessed via a browser if the user knew the file name...

You won't lose security with this method if you Restrict Access to page, and have a redirect to login page.

I'm not sure if were getting our wires crossed on this one. Storing the images in a database is the most secure way of doing things. Storing the images in a folder on the server is less secure because they could be accessed from any web broswer by requesting their file name from the server. All servers as far as i'm aware will serve up an image if it is requested without questioning it authority.
I believe there are ways of protecting certain folders on your server which is another option. But the main question should be do you need such precautions. Why are you storing the images and what are they off?

I'm sure that my reply was to agree with you. I'm not the original poster.

Hi,
I added a customized button in IE that Shows a customized toolbar. Problem is that I can't make it HIDE the toolbar. I don't know if I have to change button's CLSID in registry, as I suspect that the following key
CLSID = {E0DD6CAB-2D10-11D2-8F1A-0000F87ABD16}
refers to a button that only SHOWS the toolbar. It should have the same behavior as IE "Favorites" button.
Anyone ?
Thanx in advance!!!

Am i correct in thinking that what you are trying to do is present a custom button on screen usn html/css/jscript and then are having trouble changeing the visability?
else PM my with what you are trying to do and send me some scripts

Anybody found anything that does code coverage of JavaScript?
|
|
|
|
|
Coverage? Or do you mean the other way around?
Possibly Camouflaging scripts?
You might use server-side java-scripts or signated ones. First ones are just loaded as an object or external script and accordingly set to the appropriate read-rights par ftp.
If you just want to make it 'strongly not recommended' up to 'impossible' to understand what the script works out, well... What about crazy hieroglyphic names for variables, short-forms of if/then/else-constructs and as much functions as possible?
If you want to make it heavily difficult for the normal user to 'see' your scripts you should use an xml-http-request instance and use it as a loader for your external javascript-segments normally bound inside the body. And then replace the innerHtml of any given Element that has an id-Tag with this script. That performs a runtime/asynchronous call of the script only accessible in RAM. No temporary files, no Cookie-handling, no Session-Sets...
But if you really meant Coverage as used for covering something up, get into the details, etc. then you should install the latest opera, read anything about storing sessions and edit them in author-mode, buy a good Javascript 1.3/1.5-Reference and spent some time with HT-Tracks WebSite-Copier. With that you're on the best way to 'investigate'. You might be, because you truly don't wanted to know about simple tasks like 'hacking' and 'jacking', do you?
Well, possibly i misunderstood the whole question.
So, i really don't know if any of this might have had helped you if you're through with practicing it, but maybe?
Just try it, take your time.

hehe, thanks for trying elyphe but that isn't what I meant. Code coverage is part of testing your applications. So you run unit tests and then you get coverage stats that tell you how much of your code is tested. It is a pretty important part of testing. Wikipedia has a good explanation[^].
|
|
|
|
|
Thanks for the advice during the wikipedia link. Okay, now i know.
But to be true i would've never ever thought that there are people in this world that check how complete (or better: at which rate) a code-complex was testet.
You need those results for planning projects and to see how efficioent your coder's section is by presenting your continuous struggle to financier's, huh? (...action ...reaction; uuuaaaargh!)
Whatever, i think my first reply might have amused you under that conditions, hehe
But isn't it possible to use the watcher/debugger/slayer functions given in ecclipse, flash 8, .Net St. 2005 or even in Office's Java Script Debugger? I mean, where's the problem to filter out the JIT-Message-Handles? As far as i know you have full capability to revise any single phrase of a conduct in runtime or even run marked parts in statistic mode, so it catches what you want.
But probably i'm once again too far away from that piece of reality you've asked for.
Won't make any more suggestions, sorry, i think it's better to shut up sometimes....

No, it is for my own benefit. Would you write code without unit tests? I wouldn't anymore and I also hate to write code without code coverage analsysis too.
