Thanks. But the problem is that we aren't able to change the web page because it's made by a third party, so we can't add hidden elements to the page (or any elements, for that matter). The user has to put client info into a state database through their website, and they used to have to put all that same info into their own database. our program just captures it before it's submitted so that they don't have to input the data twice. we don't have any control over how the website is made.

Somehow I missed the IHTMLWindow2::execScript[^] method which is able to execute the specified script. To query the value of a global variable, you can provide some script to perisist the value of the global variable somewhere for example the clipboard of the window object or any other properties:
mshtml.HTMLDocument doc = (mshtml.HTMLDocument)axWebBrowser1.Document;
mshtml.IHTMLWindow2 win = doc.parentWindow;
object obj = win.execScript("window.clipboardData.setData(\"Text\",Page_IsValid.toString());","javascript");
mshtml.IHTMLWindow3 win3 = (mshtml.IHTMLWindow3)doc.parentWindow;
object pageIsValid = win3.clipboardData.getData("Text");

Dear group,
I am using the webBrowser's control as part of my project, i am wondering if there is a method in the Internet Explorer's API which identifies if an element is visible or not.
Supposingly you have got a website where scrolling is needed, that is if you want to read all the web page's content you will need to scroll down to see the rest of the web page. My question is:
Is there a method which tells you if (for example, an image) is visible on the screen or whether it is not ???
Please this is very important in my project, can anyone help  !
Thank you
Adam

Well..
You can check the size of the window and then check the position of the image.
Note however that the position of the image is reltive to the child element if that has the attribute position: set to "realtive" or "absolute".
Yea.. and you have to check how much the window has scrolled also...
<br />
The functions to use are:<br />
document.body.offsetWidth<br />
document.body.offsetHeight<br />
<br />
<object>.offsetLeft<br />
<object>.offsetTop<br />
<object>.scrollLeft<br />
<object>.scrollTop<br />
<object>.style.pixelLeft<br />
<object>.style.pixelTop<br />
By the way, these are the Explorer specific functions...

Thanx for the advice Mattias,
but i still have a problem,
thats part of my code;
CComQIPtr<ihtmlelement2,&iid_ihtmlelement2> element(pDis);

Do you have got any idea why this is happening ???

There is a form in a html file.
Several controls , such as textbox, radiobutton, dropdown menu in the form.
All the values of the controls are needed.
How to check the values before invoke the submit button?
Thanks!

Hi:
You need to use a JavaScript which is wired up to onSubmit of the form and check in that function.
If all passes, return (true) to enable the browser go ahead with the form submission, else display a suitable message to the user and return (false) to request the browser to abort form submission.
Did this help you?

hi there , can a jsp page use 2 servlets or can a jsp page consists of 2 sql statemets. my database is postgres and server is tomcat ...
sql statements are the same as ms access ...
|
|
|
|
|
1. Why use servlets when you are using JSP??
2. Yes, you can use how many SQL-statements you like from a JSP-page. However. I recomend you to create java-beans to do this. Makes your code more general and easier to maintain.
3. Servers shouldn't matter... in this case...

I have the following so far:
preg_replace('/href=("|\').+(\.htm|l)("|\')/', 'href="${5}"', $buffer);
I am trying to find all HREF attributes which link to HTML or HTM files...which it does nicely...
But then, I am trying to replace what was found, with what was found, except I want to prepend and 'underscore' to the file name...
So...
index.html
Would become:
_index.html
Please ignore the madess behind my reasons I just need the answer 
If you know what i'm doing wrong mostly in the replacement part...I would really appreciate your help...
Merci Buckets
It's frustrating being a genius and living the life of a moron!!!

Just starting to familiarize myself with dotNet web design, and don't understand the behavior I'm getting with a Web Custom Control. To play around with custom controls, I decided to build a web site navigation control built around a table that's populated with the logo, and the common links in the web site. Then I just insert this control at the top of each page in the site, set one of the properties to indicate which link should be deactivated, and I've got a nice easy to maintain navigation control.
The funny behavior I get is when I set one of the controls properties in the designer... For some reason, all the rows and columns I added to the custom control in the constructor are duplicated in code on the form the control is in! What's that all about?
If that's not enough detail, here's a brief description of how I built the control... I added a web control project to my solution, and modified the template to use WebControls.Table as the base class. Then (here's where I might be going wrong) in the constructor, I added the rows and columns I wanted my control to have, and I also added the navigation links.
To use the control, I add it to the toolbox, and drag it onto the form I want to use it on. Then I have to set a property that deactivates the link for the current form, and for some reason, code is added to the form that duplicates the rows and columns I added in the constructor of the control!

Hi there,
That is because the Table.Rows property is defined as an inner default property of the Table class and the value of the Rows property is persisted in design mode when the control is changed. So after the control has been changed, the control designer TableDesigner redraws the appearance of the table, the rows property is now updated with the added rows in the constructor and it results in the duplication as you are seeing. In this case, you need to create your own custom control designer, the sample code looks something like:
[Designer(typeof(CustomTableDesigner))]
public class WebNavigator : System.Web.UI.WebControls.Table
{
public WebNavigator():base()
{
}
}
public class CustomTableDesigner : System.Web.UI.Design.ControlDesigner
{
public override string GetDesignTimeHtml()
{
WebNavigator table = (WebNavigator) Component;
if (table.Rows.Count==0)
{
TableRow row = new TableRow();
TableCell cell1 = new TableCell();
HyperLink link1 = new HyperLink();
link1.Text = "Home";
link1.NavigateUrl = "Home.aspx";
cell1.Controls.Add(link1);
row.Cells.Add(cell1);
TableCell cell2 = new TableCell();
HyperLink link2 = new HyperLink();
link2.Text = "About Us";
link2.NavigateUrl = "AboutUs.aspx";
cell2.Controls.Add(link2);
row.Cells.Add(cell2);
table.Rows.Add(row);
StringWriter sw = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(sw);
table.RenderControl(tw);
return sw.ToString();
}
else
return base.GetDesignTimeHtml();
}
}

I tried that, but I still have the problem where the designer adds HTML code that duplicates the rows I added in the controls constructor!
I hope the code displays ok... 
<code>
... Here's the entry the designer adds initially...
<cc1:EngNavTable id="EngNavTable1" runat="server" MyLinkNumber="1">
... As soon as I modify an attribute in the custom control, all this gets added to the HTML file!
<asp:TableRow>
<asp:TableCell ColumnSpan="4" HorizontalAlign="Left" Text="<img src='images/agilityheader.jpg'>"></asp:TableCell>
</asp:TableRow>
<asp:TableRow>
<asp:TableCell BackColor="LightBlue" Width="33%" HorizontalAlign="Center" Text="Transponder"></asp:TableCell>
<asp:TableCell BackColor="LightGreen" Width="33%" HorizontalAlign="Center" Text="Laser"></asp:TableCell>
<asp:TableCell BackColor="LightBlue" Width="33%" HorizontalAlign="Center" Text="Misc"></asp:TableCell>
<asp:TableCell BackColor="LightBlue" Width="33%" HorizontalAlign="Center" Text="<a href='http://www.agility.com'>Agility</a>"></asp:TableCell>
</asp:TableRow>
</cc1:EngNavTable></P>
</code>

Do you mean the duplication of the rows is that the html markups are added as soon as the control has been changed?
[DefaultProperty("Rows"), ParseChildren(true, "Rows") ...]
public class Table : WebControl
Looking at the code above, you will see that the Rows property of the control Table will be parsed by the page parser when the control is used declaratively on an ASP.NET page. It makes sure that the nested elements(rows) are in line with the count of the row collection of the control. So the html markups which are added should represent the Rows property of the control. For more information, you can see:

Hi Neeru:
If you are looking for 3rdParty Upload components, try here:

I am trying to better understand CSS and am having problems. Maybe what I'm trying to do can't be done? Anyway, I am trying to recreate the look I've created at www.randommonkeyworks.com, and eliminating tables as much as possible. I finally saw the magic to 'div' tags, and their positioning tricks. But it appears they won't give me everything I want, unless I am overlooking something someone here may know.
I can see making the header a div, the sidebar a div, the footer a div, and the body a div, but then when I get to the purple frame I've placed along the top and left of the body, it blows up royally. Does anyone know any way to recreate that effect using only CSS?
(Even a bastardized conglomeration of a table inside of a div doesn't work, if I understand it correctly, as the div will not grow in height automatically unless there is text in it, and the top bar will not size right either. I won't go into much more details here, but I've tried.)
For a second question, how do you set up your navigation bar so that it is testable on your development hard drive, as well as on your actual site? What I mean is that if you use links like "/dir1/file1.html", in my case that would refer to "www.randommonkeyworks/dir1/file1.html", but on my development hard drive it refers to "D:\dir1\file1.html" (or something like that), so if the actual path is "D:\HtmlWork\Site3\dir1\file1.html", I can not test it on my development hard drive. And you have to use links like that on a navigation bar, because using relative links when your site has many subdirectories means that you have to massage the paths to the links on every page on a subdirectory basis, rather than just placing a chunk of code to absolute links. (That makes your site more brittle.) I've somewhat gotten around that with some JavaScript, but I want to know if there is a more elegant solution.
Thanks,
David

Question 1.
Could be achieved in many ways.
One way is to use the background property of the div.
eg:
BACKGROUND-POSITION: right top;
BACKGROUND-IMAGE: url(../library/images/RCorner.gif);
BACKGROUND-REPEAT: no-repeat
Question 2.
I recommend using relative links my friend. Makes you happier and life easier in the long term.
However, you could use some server side code to create the path to your files, reading the path form a config file. That would not work from html tough.

1) I can only get that to work inside tables. If it is not inside a cell, the image will not extend to the other side of the window. (It won't extend down the entire length of the left side of the screen, either.)
2) The problem with relative links rears its ugly head when you go to insert a 'standard' header/sidebar, as was implemented on randommonkeyworks. If your 'common' stuff is in a 'common' subdirectory, the relative path to that subdirectory changes for each subdirectory on your site, keeping you from inserting the same relative links through shtml or whatever, unless you take other measures, as I have. I am wondering if there is a better way, though. As you indicated, with Javascript disabled, my way blows up.
(I don't have access to the server, but can do php on it, I believe. I just have not wanted to learn that in addition to everything else. But if I do that, the php won't work on my machine while testing the site, I believe. The Javascript seems to be the cleanest solution. Grrrrr...., unless I am wrong.)

why not? it's freeware... both server (Apache) and some PHP (e.g. PHP Triad http://sourceforge.net/projects/phptriad/[^] - all in one, even with DB, easy to set up - I used it while on high school... it sure won't be a problem for you  ).

1. ok, change the attribute:
BACKGROUND-REPEAT: no-repeat to BACKGROUND-REPEAT: repeat-x
2.
Well.. I am using a CSS-file. and the path is relative to that CSS-file.
In C# I am able to specify which CSS to use in my page with the following code.
in the client-page..
<br />
<link id="styleLink" type="text/css" rel="stylesheet" runat="server"></link><br />
in the Codebehind...
<br />
protected System.Web.UI.HtmlControls.HtmlGenericControl styleLink;<br />
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
string style = HttpContext.Current.Request.ApplicationPath + "/" + <br />
System.Configuration.ConfigurationSettings.AppSettings["GeneralStylePage"];<br />
style = style.Replace("//","/");<br />
styleLink.Attributes.Add("href", style);<br />

That will only repeat the background IN THE AREAS WHERE TEXT APPEARS. For this reason it won't work if you want the header to automatically expand itself to the right edge of the page. (If your line of text is: "My Text", and it is displayed in 10pt, the background will only be about 1" in width, and will end right after the final 't'.)

I do not really understand what you are trying to do, and how it is different than my solution, or if it is better. What you imply is that you have a C# application running on your server, serving your pages, and that "ApplicationPath" gives you the root to the base directory of the site (I'm guessing). If I'm guessing correctly, that still doesn't explain how to overcome the problem I pointed out, in being able to test your site on your hard drive from any random subdirectory as you are designing it, and then having it work flawlessly upon moving it over to the final server location. (How does it know that the root isn't "D:\", but rather "D:\Documents\Work\PrototypeSite"? The code above does not seem to address that question.) But as I said, I cannot really understand what you are trying to do from the information you have given.
(In addition to that, I don't have access to the server, as I said, and I cannot run a C# application on it.)
Thank you for taking the time and trying to explain, though. I appreciate it.
