I don't understand your request. Can you be more specific about what is it that you are trying to do.

Use the System.IO namespace. DirectoryInfo for instance. Google for some tutorials if you don't know how to use it...

Hi all,
I have a javascript function which will capture the screen coordinates of a browser window on a left mouse click.
I have one image on a browser.When i click on the image,i would like to open some textbox control instead of capturing of screen coordinates(which happens by means of javascript function i have).
I couldn't able to mask that javascript function which captures screen coordinates.
What i want is that specific javascript function should be off when i click on the image on a browser.When i mouse click on a browser other than a image,javscript function should work well and capture screen coordinates properly.
HOw can i acheive this?
Plz help me out of this problem.

I'm guessing you have a document.onclick = myCursorFunction....if that's the case, then just set the onclick of the image to point at a different one...

I have a webpart that displays departmental news. Every department have different news section for instance Admin dept have three news section:
1- Admin
2- HR
3- General
Sales dept have four:
1- Company Sales News
2- Stock News
3- Global Market News
4- Sales Forecast
Now, I want to expose these sections as properties of my WebPart so if a Sales user is logged in; when he will enter Edit Mode; he sees all four sections in Sales Dept and from which he can choose what all it is that he wants to see on the webpart.
I can hardcode something like this:
protected bool _CompanySales = true;
[ Personalizable(PersonalizationScope.User),
WebBrowsable,
WebDisplayName("Company's Sales News"),
WebDescription("Use this property to show/hide Company's Sales news")]
public bool CompanySales {
get { return _CompanySales ; }
set { _CompanySales = value; }
}
protected bool _StockNews= true;
[ Personalizable(PersonalizationScope.User),
WebBrowsable,
WebDisplayName("Stock News"),
WebDescription("Use this property to show/hide Stock News")]
public bool StockNews{
get { return _StockNews; }
set { _StockNews= value; }
}
protected bool _GlobalMarketNews= true;
[ Personalizable(PersonalizationScope.User),
WebBrowsable,
WebDisplayName("Global Market News"),
WebDescription("Use this property to show/hide Global Market News")]
public bool GlobalMarketNews{
get { return _GlobalMarketNews; }
set { _GlobalMarketNews= value; }
}
But I wouldn't have any knowldge of these sections because they are stored in the database. So I guess my question is; how can I dynamically define properties of a webpart by pulling the data from a datasource?
Thanks in advance.

I'm creating an ebay type website for a class, and the user can open a pop-up window to select a picture from the folder on the server for their product.
The issue right now is that all images for all users are uploaded to the same folder. I need some control in C# or ASP.NET that will create a new folder when a new user is created that only they can access so that only their pictures will show up.
Some other information that may be relevant is that I am NOT using ASP.NET membership controls; I'm using Forms Validation.
I've searched online for the solution until I'm blue in the face, and I've had no luck. Is there anyone that has advice for me about this?

Sthepanie i faced the same problem and at the end i had to make my own solution, and i will write it for you, i hope you can understand the next lines, im not good to explain.
Onto dataBase you must to create three tables, they are users, images, and the relation images_owner.
for Example:
Users images_owner images
coduser (pk) codrelation codimage (pk)
nomuser coduser urlimage
codimage
You already have a folder to save all the images, right here you must to create a particular folder for every user, in another words you created the user, created the folder. (use the coduser like folder's name)
the sentence to create the folder is:
DirectoryInfo di = Directory.CreateDirectory(url);
Invoice the System.IO library to create server folders.
Right now you must to have this folder
allImages/coduser
You can update your images for any particular user, when the user login in the site, write a session var with the coduser code, and every time that you upload a picture (fileupload control)
fill the relation table image owner and save the image onto particular user folder with the codimage like name.
To show the image select all the codimage from image owner where the coduser is the session user code.
keep Learning and you never will be out of date...

ive just took the plunge with vs2005 from vs2003 and there are a couple of things that are truly boggling me!
1. i like to have a page called 'basepage' in which i add lots of useful functions. every page i add to my project inherits from basepage so it has easy access to all my pre-built functions.
i have created my basepage but it does not appear in the intellisense list after the 'inherits' statement when i type and it does not appear to be known as a class. why is this???? its driving me nuts!!!
2. i like to setup namespace imports for heavily used namespaces such as system.data.sqlclient and system.text. i cannot find the utility to do this where it used to be nor does the help give me any clues.
please help a very flummoxed vs2005 noob!

Hi there,
1. Where do you define the basepage class? In the App_Code folder or a seperate project? Do you try to compile the project before using it?
2. You can define the namespaces in the namespaces Element for pages[^]

hi thanks for your reply.
the basepage inheritance seems to work now  which baffles me even more.
thanks for the namespace tip, ive got it sussed now

Hello friends I have read all the articles regarding sending emails through an application...all of these includes the use of an SMTP server...Can anyone tell me how to use the Hotmail or GMAIL server or any other SMTP server available online(and not IIS SMTP server). These requires the use of secure login...err..How to do it ? Plz help.

AFAIK you can't. Hotmail (at least used to) uses HTTPMail, and most of the other web based providers prevent relaying to stop spammers. Best bet is to use your company's mail servers, or if you just want to send, you can download several free SMTP servers from t'internet.

Hello,
I am need to get a connection string details. I am doing as follows:
01: Dim connectionStrings As New ConnectionStringSettingsCollection
02: Dim connectionString As New ConnectionStringSettings
03: connectionString = connectionStrings.Item("MyConn")
04: Console.WriteLine(" Connection String: ",
connectionString.ConnectionString) *** ERROR ***
05: Console.WriteLine(" Name: ", connectionString.Name)
06: Console.WriteLine(" Provider Name: ",
connectionString.ProviderName)
I get my first error on line 04
System.NullReferenceException: Object reference not set to an
instance of an object.
To check my connection string I did the following:
Dim otherConnectionString As String =
ConfigurationManager.ConnectionStrings("MyConn").ConnectionString
Response.Write(otherConnectionString)
And I get:
Provider = Microsoft.Jet.OLEDB.4.0; Data Source = C:\Documents and
Settings\User\My Documents\Visual Studio
2005\WebSites\MySite\App_Data\MySite.mdb; User Id=; Password=;
Which proves I have the connection string with name MyConn in my
web.config.
Could someone tell me what am I doing wrong?
I tried everything I could think off.
Thanks,
Miguel
