COM interop: Is it possible to pass a ASP.net web control (say, a textbox) as a reference type variable to a COM method? If yes, how?
Thanks,
SK

I don't think so. What is the reason for doing that?
|
|
|
|
|
To be able to use the same COM biz object (that references VB form controls) in both legacy VB6 windows client and new ASP.Net web client.
Thanks.

I have a label control in content page like below:
<asp:content id="Content1" contentplaceholderid="MainContent" runat="Server" xmlns:asp="#unknown">
<asp:label id="lblMessage" text="Hello" runat="server" height="19px">
Text="" Width="160px>
Now, how can i get the reference of the label through javascript? When I tried as below, I am not getting any vaue.
var strmsg = document.getElementbyId('lblMessage').value;
I also used the generated id by seeing the View-->Source of the browser. But still I'm not getting any value? How can i resolve this? Can anybody please help? I require the value for some other operation.
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

ASP.NET render label as a HTML span and prefix it's containers (content place holder in your case) id with it's id. Try this
var strmsg = document.getElementbyId('<% lblMessage.ClientId %>').value;
|
|

N a v a n e e t h wrote: var strmsg = document.getElementbyId('<% lblMessage.ClientId %>').value;
I think it should be:
var strmsg = document.getElementbyId('<%= lblMessage.ClientID %>').value

That's correct. I missed the =.

I Have One Project[Solution] Called HRMS. Under this solution two web projects one for User Side and other for Admin Side. and also different Logon Pages for these two projects. i added the following forms autentication code in the web.config file for each project. But when am compiling am getting the below mentioned error. How can i use two forms authentication for Loging differeng Logon Pages.
Solution : HRMS
Projects
Project 1[User Side] : E:\HRMS\
Web.Config
<authentication mode="Forms">
<forms name="appNameAuth" path="/" loginurl="Login.aspx" protection="All" timeout="30">
Project 2 [Admin Side]: E:\HRMS\Admin\
Web.Config
<authentication mode="Forms">
<forms name="Admin" path="~/Admin/" loginurl="~/Admin/Admin.aspx" protection="All" timeout="30">
Error 1 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. E:\HRMS\Admin\Web.Config

Is there any reason for nesting the web.config? You will have one web.config which is in HRMS directory and another one in HRMS\Admin directory. Are you overriding anything in the second web.config?
I'd suggest to separate it with folders rather than creating new project. You will have only one project which contains all ASPX files and one configuration file. So you will end up with a folder structure something like
Solution Directory
--HRMS
----Files
--Admin
----Admin files
--web.config Now admin will not be a separate virtual directory and I believe it will solve your problem.

Keep it in the Cache object with user id as key and reload from there for subsequent requests.

You said you have a control which takes time to load. So put only the items required to fill that control in cache and not the whole page. Follow these steps
1 - Check cache has data
2 - If not, get the data from database (or somewhere), fill the cache and populate your control
2 - If cache has data, get the data from cache and populate control.
Check this[^] article and read about Cache arbitrary objects in server memory
If your data load is fast and your control is taking time to render the data, you can keep the rendered HTML of that control in cache and reuse it.

Hi all...
Im dynamically adding data to a label which is placed in a panel. but the problem is that as the label fills up
the panel length increases leading to scrollbars.
I want the scrollbar to be to be pointing at the end of the panel.
Here is the code sample
<asp:Panel ID="Panel1" runat="server" BackColor="White" BorderColor="CornflowerBlue"
BorderStyle="Solid" BorderWidth="1px" Height="250px" ScrollBars="Auto" Width="100%" CssClass="filter">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="Label3" runat="server" BackColor="White"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSendMsg" />
<asp:AsyncPostBackTrigger ControlID="Timer1" />
</Triggers>
</asp:UpdatePanel>
</asp:Panel>
Bye

Hi Sam,
I tried working on the sample and it is working fine.
I meand the scroll bar is at the end (right end) of the panel.
You can try with div tag instead of panel:
<div style="overflow:auto; width:auto; height:250px; border-color:CornflowerBlue; border-width:medium; border-style:solid;">

Could it possibly have something to do with F:\MyProject not being a valid path?
Open the sln file in notepad and look at the paths.
only two letters away from being an asset
|

Remove that project from solution and re-add it. Always try to keep solution in the same directory where your files are placed to avoid such kind of problems.

I am creating an image of text, having each letter in different color. i have to place each letter near by the previous letter using the pointer.
For that purpose i need to know the size of the previous letter.
How to know the width of the letter used? 
|
|
|
|
|
Take a look at the MeasureString method.
Despite everything, the person most likely to be fooling you next is yourself.

Mr Guffa,
thanks for your kind reply. actually the thing here is i am creating an image, i have to check the size of the letter may be in pixel format so that after its width i have to point the next letter.
Hope you get my requirement.
|
|
|
|
|
Yes, I understand your requirement. Read my previous post again.

Hi All,
Can some guru tell me how can I debug an ASP.net web application in Visual Studio.NET 2003? I inserted a breakpoint in the page load code and hit F10, but the application opens teh web form in the browser rather than goes into the code to execute step by step.
I am using Windows XP pro, IE8.0 Beta, and IIS 5.1
Thanks heaps.
