We are building an ASP application with SQL Server 2000 as a back end.
What is the best way to upload images to the server?
Thank you,
Anastasia.
Hope someone can help with this.
i am trying to upload images from an asp.net or vb.net front end to a sql server db.
I can upload the image fine if I first save the image to a file and then upload but my question is whether I can upload the image without first saving the image file. What i would like to do is to capture an image with a digital camera and without saving it first (an extra step for the user), upload it to a sql server db.
Is this even possible.
Thank you,
Biirir
Hello,
I have 3000 images to upload in SQL. I have a page that does it in ASP.net 2.0 1 by 1 but i am looking for a faster way. The targeted table look like this
*ID (int) ImgSize (int) ImgContentType (nvarchar 50) ImgFile (image)
Thanks for the help.
In my continuing saga with writing my little real estate application, I've got the need to upload images to a folder within the website and then capture some image information in a db. I know there are many ways to do this, and have read lots of them. However most answers don't fit what I'd like to do, or they're too complicated for me. Anyway, thought I'd write it from scratch. So, I have 2 pieces of code, 1 that uploads the image to a folder, and another piece that captures information to a db. The first part works great. The image file successfully gets uploaded. Problem lies in the db insert code. It's not capturing and writing to the db. Here's my code, and thanks in advance for your help!

I am trying to upload a file in ASP.net 2.0 to a SQL database using the FileUpload control. I am doing this by way of a typed dataset.Here is my code.Dim rta As New ResponseTableAdapterDim rdt As ResponseDataTable = rta.GetResponseByID(1)Dim rr As ResponseRow = rdt(0)Dim fs As New FileStream(fu.PostedFile.FileName, FileMode.Open, FileAccess.Read)Dim br As New BinaryReader(fs)Dim image() As Byte = br.ReadBytes(fs.Length)br.Close()fs.Close()rr.UploadFile = imagerr.NameFile = fs.Namerta.Update(rdt)The code runs without an error but afterwards I find that nothing has been stored in the UploadFile cell in the database but the file name has been stored in the NameFile cell in the database. Any ideas?Your help is much appreciated. James

Hello Everyone,
I have a report which runs in local mode and while designing the report I have placed a single image control inside the list box as I don't know before hand how many images are there :
What is the way to show all the images using the one image control inside the report viewer control. ? Can be 2 or 3 or 4.....

Do you have to use the sqldatasource in conjuction with another control like gridview or dropdown list?
I'd like to check to see if a record exists in one table before inserting data into another.
thanks
Hello.I'm new to ASP.NET and trying to write data to a Microsft SQL Server. I have created a SqlDataSource control, which is 'connected' to my SQL server.Now my question is how i can put data in the database throw the control, and read data from it. I've read the site, but it's still unclear for me..Greetings!

View 4 Replies View RelatedHello:
I am having a little issue with an error that is frustrating me. I have a SqlDataSource within an asp:label control and also have a two dropdownlists inside that asp:label control also. When I select from the first dropdownlist, it should enable the second dropdownlist with the populated data, but instead I receive.
The SqlDataSource control 'sqlGetMLSByCity' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
Any ideas why this would be? Here is the web from portion:

I have an SqlDatSource that I have fully setup at design time, but I don't want it to open and load as soon as the page loads, instead I want to open it based on a condition.
How do you do that with a DataSource?
I know that I can simply remove the Select query, and then set it at run time, but I'm looking for something better, that allows me to have the Select query set at design time, in part because I have a lot of parameters.

I have not found anything useful on the Wizard control. Anything I can find gets to the last step and then just takes the info you supplied and applies them to a bunch of Label.Text's - none that do work.
So I am building a Wizard control for an HR system that will insert the information into SQL through a SqlDataSource. The problem is, only the controls that are present in whichever step is currently selected in VWD will appear in the Command and Parameter Editor.
I tried to work around it by selecting the first step, then applying the controls in step 1 within the Parameter Editor, but when I go back to do step 2, it erases everything I just did for step 1.
How do I implement the Wizard with a SqlDataSource?
I have a gridview that is tied to a SQLDataSource control. As the gridview is filled some of the ASPX code calls some code in the code behind page. Where I am having trouble is that in one of these calls I need to some how pass the id filed ("LISTID")of the table for the SQL statement in the code behind page and I'm not sure how to do it.
The code behind function is always using the same id and I do not know how to change it. Below is all the code.
Here is the calling code in the ASPX page.

I have a gridview that is filled from a SQLDataSource control when the page loads.
I need to do some updates and delets on this data and I wanted to know can you add more than one SQL statement to a SQLDataSource control or do I have to have a seprate control for each operation?
The SQL currently is just the standard SELECT *, I cannnot see a way to add statments.
Thanks,
Ty
There is something I don't understand or I am just missing something here.
Why is it that I can place an SqlDataSource1.Insert() or update, or delete, but not an SqlDataSource.Select() inside a button click event "for an example" without getting an Compilation Error?
Thanks,

I have dragged 3 SqlDataSource Controls to the WebDesigner and none are appearing graphically in the Designer View, but they are in the Source View. How can I get the control to appear in the designer.
Thanks,

When I configure a SQLDataSource control I want the following where clause...
WHERE (RegionID = @RegionID AND DistrictID IS NULL AND CampusID IS NULL) OR (DistrictID = @DistrictID AND CampusID IS NULL ) OR(CampusID = @CampusID AND UserRole = 'CampusAdmin') OR (CampusID = @CampusID)but it gets reformated as....
WHERE (RegionID = 'Region10') AND (DistrictID IS NULL) AND (CampusID IS NULL) OR (DistrictID = 2) AND (CampusID IS NULL) OR (CampusID = '999999103') AND (UserRole = 'CampusAdmin') OR (CampusID = '999999103')I don't think these are functionaly equivelant, are they?If not how do I stop the 'wizard' from reformatting the SQL where clause?Thanks
I set up a Sqldatasource control in 2.0 and I can retrieve data through a SQL Server connection from a stored procedure. My problem is when I set up the insert command object through the wizard for the Sqldatasource control with another stored procedure for inserting data and call the insert method of my Sqldatasource object i get nothing not even an error it just goes through the code like nothing was wrong and I don't get anything inserted. I don't know if this could be a problem but one of the parameters in the stored procedure is declared like this: @return tinyint output. I don't know how the Sqldatasource accounts for return parameters. Here is the code for the insert for the Sqldatasource object.<asp:SqlDataSource ID="sdsMain" runat="server" ConnectionString="<%$ ConnectionStrings:SN_CUSTOMERConnectionString %>"InsertCommand="uspSNOrder_Promo_Live" InsertCommandType="StoredProcedure" SelectCommand="uspOPFillPromo"SelectCommandType="StoredProcedure"><InsertParameters><asp:ControlParameter ControlID="ddlPromo" Name="promoid" PropertyName="SelectedValue"Type="Int32" /><asp:Parameter DefaultValue="1" Name="datasourceid" Type="Int32" /><asp:Parameter DefaultValue="0" Name="datasourcekey" Type="String" /><asp:Parameter DefaultValue="9" Name="salesroomid" Type="Int32" /><asp:Parameter DefaultValue="9999" Name="userid" Type="Int32" /><asp:ControlParameter ControlID="txtFName" DefaultValue="" Name="firstname" PropertyName="Text"Type="String" /><asp:ControlParameter ControlID="txtLName" Name="lastname" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="txtAddress" Name="address" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="txtCity" Name="city" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="txtState" Name="state" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="txtZip" Name="zip" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="txtPhone" Name="phone" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="txtEmail" Name="email" PropertyName="Text" Type="String" /><asp:ControlParameter ControlID="ddlStatus" Name="status" PropertyName="SelectedValue"Type="Int32" /><asp:Parameter DefaultValue="0" Direction="InputOutput" Name="return" Type="Byte" /></InsertParameters></asp:SqlDataSource>Thanks in advance
View 1 Replies View RelatedDear all,I am couping a dropdownlist and a sqldatasource control to display a column from a database of SQL/Server on browser. However, when I tried to configure the sqldatasource to let it get data from SQL/Server, it always report an error. It normally happens at the first step of creating new connection. After I specified the correct sql/server instance name, using SQL server authentication, and select a database name. Even the connection test can sucessfully passed. However, when I click the "OK" button, an error message saying "object reference not set to an instance of an object" popped out and I could not add new connections. The strange thing is that after I reintall the visual studio 2005 service pack 1. It will function properly for a while. After sometime, it will fail again. Anybody has suggestions? Thanks a lot!

Is it possible to place a stored procedure in a SQLDataSource control that needs a variable input then run it later?
DETAILS
I have 2 pages with gridview controls that are linked to a SQLDataSource controls.
What I would like to do is when the user clicks on a link in the gridview of the first page I want to take the value of the link clicked and pass it to the second page where it is placed into a variable that would be used in a WHERE clause to fill the second pages gridview.
I have no problem getting the value into a variable in the page load event of the second page. What I would be nice is since the gridview is already tied to a SQLDataSource control with the columns specified is if I could some how pass the variable to a stored procedure in the control so I don't have to manually pull and fill the data.
Any thoughts would be apperciated.
Thanks,

I am trying to use a 'timestamp' type column with SQLDataSource for concurrency control with SQL Server. I'm getting the following error:
Operand type clash: timestamp is incompatible with sql_variant
It appears that the problem is that the value for the Type property of the Parameter (which was generated by the SqlDataSource wizard) is Object which maps to 'sql_variant' rather than to 'timestamp'.
I know that the older way of doing things with SqlDataAdapter, SqlCommand, SqlParameter can handle timestamps because SqlParameter has a SqlDbType property that can have a value of SqlDbType.Timestamp, but I don't see how to do this with the newer SqlDataSource, Parameter classes because the Parameter.Type property (of type TypeCode) doesn't have a Timestamp value.
Has anyone been able to use a 'timestamp' type field with SqlDataSource?
Here's my sample code:
