[Code]....
I dont really know how to use array but willing to try if it is needed.
I want to create a if statement which i select an area on a imagemap then the corresponding label discription will appear and corresponding image. The code if what i have so far
Protected Sub ImageMap1_Click(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ImageMapEventArgs) Handles ImageMap1.Click If e.PostBackValue = "ME" Then
Image1.ImageUrl = "F:WebSite1imagesone.jpg" & label1.text="Me" <------- How do you join a label and image selection in one if statement i keep getting errors on this and image doesnt load also
ElseIf e.PostBackValue = "Car" Then Label1.Text = "CAR" & Image1.ImageUrl = "F:WebSite1images wo.jpg" ElseIf e.PostBackValue = "Mysister" Then Label1.Text = "My sister" &Image1.ImageUrl = "F:WebSite1images wo.jpg" Else Label1.Text = "" End If End Sub
I have seen a few ways to show images randomly every time the page is entered.Can this type of thing be done in a master page as each time a child page is entered it has a new image?
I am looking for a solution (APIs, etc.) for handling a similar experience as cafepress.com. I need to be able to upload images (preferably multiple at a time) and be able to map my uploaded images to various product images (clean stock images of shirts, mugs, etc.). I also want to give the user some very basic controls over the images they upload such as cropping, resizing, levels, etc. I am looking for .NET solutions (if server-side).
I have implemented a adrotator to display random images using ajax. I also need to display another image at left side corner on the adrotator image continously.
I have text field on a sql server table and I retrieve it on string variable using datareader : string result = reader["MyTextfied"] but I have this errors ( text or binary field cannot be troncated ) My text fied contains a large of text
i have a datareader who read from data field from sql server, this field is datetime format now, when this field is null it returns 01/01/1900!! how can i manage it without if or some check, is there a property in datareader or sqlserver properties who i can return null value from datetime field?
I use a SqlDataReader to get fron sqlServer a row af a table. This table have a text field where I store a Xml configuration. In one case this Xml grow up to 650Kb. When I get the field from the datareader it cost amost 2 seconds:
INFO 2010-04-16 09:46:40,559 [12] Cms.dataContenido - readed INFO 2010-04-16 09:46:42,356 [12] Cms.dataContenido - XMLContent
I have a table with just a column and a row in a table that it save just a file with size 1.5 GB ! C# application and sql server are in different machines. I want to read that file by DataReader every 100 MB then save all 100 MB files to disk by "FileMode.Append" for file stream and collect them to one file.
i have a select statement which returns a column value.
id like to display the lowest column value there is, but if there are multiple rows with the same (and lowest) value id like it to be random which one of the rows is selected.. how would i do this? my select statement is currently:
SELECT TOP (1) url, ABS(r1 - @r1) + ABS(r2 - @r2) AS difference FROM type ORDER BY difference
this picks the one lowest result for me, but if there are multiple duplicate lowest results id like to select them, and show one at random..?
I am working on a project for a market research company that needs to select and have it displayed to my gridview. I need a select statement that will randomly put on my gridview the following:
Recruitment Goal 21 people and out of those people 10 people have to be male, 11 people female, 9 of them white, 9 of them black, 2 of them hispanic. Is there a way I could do that? I was thinking of doing a stored procedure and doing something like
Select TOP 10 * from Canidates where sex = 'Male' order by newid() Into #tmp Select TOP 11 * from Canidates where sex = 'Female' order by newid() Into #tmp Etc... and then just selecting from the Temp Table.
I am looking for some solution of the random user image.I created some image and calling it from database if user has no image.But i dont like it, it is quite ugly.Is it exists some random image generator, like here in stackoverflow the the user has no photo.
I am developing an application in which i have to store image in database SQL server2008. I want to use upload file control and only want to upload .jpg and JPEG file and view this image in image control . And when i want to update this record i can update that image too..
I'm having a method that exports content from the database to excel files. The method taks as paramaters a DataReader param and a int param - the number of rows. For the number of rows i'm using a dataset, wich i fill using the same query as for the datareader. So I'm executing it twice... Is there a way I can avoid that? get the number of rows from the datareader?
I have a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but realistically should never be more than 50 to 100 items from the listing of about 3000 items.
I need to collect the list of selected items from the drop down list and retrieve each of their full records from the item master and populate a gridview.
I have a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but realistically should never be more than 50 to 100 items from the listing of about 3000 items.
I could really use some building the SQL statement to select the choosen record data. I think I have the selection list worked out by populating an array but I am not clear on how to build the SQL query.
I am getting an error that an open DataReader associated with this Command, when I'm not using datareader(though probably executereader() is the same thing) how would I close this if I don't have a datareader present?
using (SqlConnection conn = new SqlConnection(ConnectionString)) { SqlCommand cmd = new SqlCommand("spSelectAllTypes",conn); cmd.CommandType = CommandType.StoredProcedure; [code]...
I just want to be able to databind a bunch of dropdownlist in one open connection. (before I had multiple open and closes for each control)
