Check out codedom compiler namespace

You can dynamically create and compile assemblies at runtime.

Just like you create any other file.

It is not a good idea to create ASPX pages on run time. What you are trying to do can easily done using URL rewriting. Read the articles on URL rewriting.

As per problem description provided, I may guess that you want to create a dynamically generated page based on some inputs e.g from user or some XML that contains control details.

On this thread I would like to include that, It can be done by using some utility frameworks e.g.

1. MonoRail[^]

2. NVelocity[^]

Both of the framework, accept a template file and render the output file in desired format. Although It is not pretty much easy as it sounds.

I hope by going through some quick starts at given link you may be able to get some where.

Dynamically creating and positioning controls

Hi all,

I am creating a type of control that is used to display fill-in-blank questions, the control will have a drop down list in the location of each blank with 4 options to choose from, like this

The elephant [is, are, us, we] a very big Mammal that [eat, eating, eats, ate] plants...

[is, are, us, we] = drop down list with 4 options that the student uses to choose the best answer.

The question is how to dynamically create drop down server controls AND position them in the correct place within the words of the paragraph?

Any ideas?

Thanks Smile | :)

Easy way is to put this inside a template column of a GridView. ASP.NET will maintain the viewstate for all the dropdowns.

That show you have no idea about ASP.NET. I reiterate, you can't use ASP.NET for doing such things.

deepthy.p.m26-Jan-09 23:15

26-Jan-09 23:15

I use the following code to disable back in IE

In javascript i use

window.history.forward(1);
]

and on code side

protected void Page_Init(object sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
}

protected void Page_Load(object sender, EventArgs e)
{
Response.AddHeader("pragma", "no-cache");
Response.Expires = -1;
}

But When i move from login page to firstpage it should not retun to login page
when the back button is clicked.

right now its returning to login page.How can i avoid that.

Good grief - did you search in codeproject prior to posting. This has to be the most asked question in this forum. Scroll down a few days, it'll be here somewhere...

Using WMI win32_share in asp.net page not working on IIS6?

leeoze26-Jan-09 22:11

26-Jan-09 22:11

hi,
I'm trying to create a folder sharing using WMI win32_share on an ASP.NET c# page.

while running it using the visual studio 2008 it works great.
But after I publish it to the IIS and run the WebPage nothing happends?!
it's seems like the page was loaded fine but checking the folder I see no share was created.

Any ideas?

I'm using .NET 3.5, visual studio 2008, c# webapplication.
IIS 6 server.

here is the code

string shareName = "Test";
            string CUDir = @"D:\Test";
            ManagementClass managementClass = new ManagementClass("Win32_Share");
            
            // Create ManagementBaseObjects for in and out parameters
            ManagementBaseObject inParams = managementClass.GetMethodParameters("Create");
            ManagementBaseObject outParams;
            
            // Set the input parameters
            inParams["Description"] = "";
            inParams["Name"] = shareName;
            inParams["Path"] = CUDir;
            inParams["Type"] = 0x0; // Disk Drive
            // Invoke the method on the ManagementClass object
            outParams = managementClass.InvokeMethod("Create", inParams, null);

tnx

Re: Problem solved...

leeoze26-Jan-09 23:16

The problem was on the IIS application pool.

in order for me to use Win32_share I need to setup the predefined Identity of the Application Pool to Local System. otherwise I have no premissions to use WMI.

I can also set the Configurable to a user with the right premissions to do the same.

To access the Identity you need to open the IIS Manager.
Colpase the Apllication pools and either create a new pool to be used or edit the deafult by right click and Properties.
Go to the Identity tab and choose your wish.

Also do not forget to go to under Web Sites and on your selected website/virtual directory properties to set under the Application settings the Apllication pool to the one with the new premissions.

in such a situation you will have to hide column after binding it...
but if you hide that column using grid property of hiding it then you wont be able to use that data in it or data will be lost on postback...

U can use bound field.

BoundField b = new BoundField();
b.DataField = field name you would like to bind with.
b.HeaderText = " ";
datagrid.Columns.Add(b);

Hello,
I have put a combo box on a form in VB.NET; which will be populated through oracle table "PLACENAMES". I wish that when a user types the name of place in the combo box the relevant / like place names should be auto dropped down for his selection, and if it is a new place name then this new place name should be saved in the table on pressing the enter key.

Please guide me how to achieve this feature.

Thanks & Regards
Girish
