I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........
I am trying to link to a third-party site. On that site is a list of links, and I need to be able to link my site to destination of one of those. The problem is that the links are not going to URLs, they're using ASP.NET postbacks to display the description of each item in the list.
Here is the URL where the list is. I want to be able to link to specific entries in this list.

I created a mvc helper that add some textbox with javascript.
I want to check if JavaScript file already exists on the page and if not I need to add it to the end of the page.
How can I do it in MVC 2?
Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.
Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.
How I can I do that in javascript?
I have an default.aspx page that I'm trying to have redirect the user to a different page depending on whether or not their deviceId is stored in the SQL Server database. It should direct the user to the login.aspx if the record for the user is found or to the newdevice.aspx page if there was no record found. I want this to occur on Page_Load but have not been able to figure it out so far.
View 3 RepliesI have a function that loops through the control on my page to set attributes. This works fine, except that I only want the attributes to bet set on the controls on the content page, and not on the master page. Is it possible to check where the control resides? Or to only loop through controls on the content page?

I have upgraded web application from VS.2008 to vs 2010. I was using previously ReportViewer 2008 control in a page and replaced with 2010 ReportViewer Control.

View 3 RepliesI have a property object that has many activities associated to it. I want to delete all the activities and then add specific ones back in. I am doing this all before the objectcontext save. I am using multiple objectcontexts and attaching/detaching the objects. I am getting the property from the propertyreository objectcontext which is the primary context. Then I get the user which takes a bool to determine if I want to detach from the userrepository object context. I attach to the propertyrepository.
All is good but when I remove all the activities from the property object (entityobject) and then try to attach the activity that I retrieve from the database I get the error: key already exists in the ObjectStateManager Error. When I remove all the activity entity objects from the property entity object they are not really deleted from the objectcontext or the database until I use the save() on the objectcontext which will change all the entity object statuses. How then after I remove the activity do i add it back to the property.Activities?

I have a database for a shop. Now I have run into problem when I'm adding products. I have a page where i add general info of the product that will be adding to the product table. Then I should have a page where I can add colors and sizes and so on. But how do I do that? When I add the product I set a price in the productdetail table and colorId and sizeId is sett to null. If I add a color to the table how do I do this the easiest way? I will not have a product where both colorId and sizeId is null. I have this SP and table structure. Then I'll do the same when I add sizes.

How do, to see if an object exists? For example, I want to see if there is a DropDown on the page. I tried this:
if (object != null) {}
But it does not work.
I am very new to this and have watched a lot of the videos. While trying out VWD2010 and SQL2008 Express, I come across many things, I just don't know how to do. Here is the latest:
I have a Table
UserId - Int - AutoIncrement
FirstName - Var(10)
LastName - Var(10)
I also have an ASP web page that allow the user to enter a first name and last name. It also has a button to submit. What I would like to do is have a Select statement check to see if the name already exists, then send a comment back to the user via a label. If it doesn't exist, then I would like to Insert the info and then again inform the user via label.
SelectCommand="SELECT COUNT (UserId) FROM Users WHERE ((FirstName=@FirstName) and (LastName=@LastName))"
InsertCommand="INSERT INTO User(LastName, FirstName) VALUES (@FirstName, @LastName)"
<InsertParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</SelectParameters>
