More details about the errorcode would be helpful, you may need to update the Web.Config file to show the complete error message, look at the customError section for more details, if you can post the more detailed information then maybe I can help..

Check the sql server connectivity. see machine.config for more details on connectionstring which is used for webparts

hi all,
i am creating a page in asp.net using c#.To insert the data,i just wrote the sql command for inserting and followed the same for edit and update.
for example..
string myinsertQuery = "insert into DriveUnits(SerialNumber,CorporationID,CorporationDivisionID,HWVersion,DateManufactured) values('" + SrNumber_TBox.Text + "','" + Session["corporationid"] + "','" + CorporationDivisionID + "','" + Hwversion_Tbox.Text + "','" + DateMFD_TBox.Text + "')";<br />
SqlCommand myCommand_insert = new SqlCommand(myinsertQuery);<br />
myCommand_insert.Connection = myConnection;<br />
myCommand_insert.ExecuteNonQuery();<br />
myCommand_insert.Connection.Close();
but instead of writing code in cs file,i just want to call a class
so that wherever we need to insert data,we can just call the class and the functions defined.
i created a class and a function and pass parameters.but it is showin invalid arguments..
plz give ur suggestions on creating a class and its functions.
Thanks in advance,
cheers

not sure i got you..
maybe this is what you want..
Using static method.
public class MyDBMgmt{
public static bool ExecuteSQL(string cmdText)
{
return true;
}
}

Is this ASP.NET 1.0, 1.1, or 2.0 ? What errors are you getting ? You should certainly put all your SQL in a class, so that it's in a seperate layer to the rest of your app, and can be reused as needed.

Hi all
i have some code above. I have Some problem when i save this image is type Gif/ JPG so this image show but when i save is PNG is not yet And when i check C:\\demo.Png is Exist and open is ok but on web is not ok. ????
byte[] byImg = objimg.getBytes();
using (MemoryStream objStream = new MemoryStream(byImg))
{
System.Drawing.Image img = System.Drawing.Image.FromStream(objStream);
Bitmap bp = (Bitmap)img;
//Check this image can show
bp.Save("C:\\demo.Png", System.Drawing.Imaging.ImageFormat.Png);
// Show image
bp.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Png);
}
|
|

|

Problem is the format of PNG is not compatible with the Response.OutputStream method directly, you need to store the image in a memorystream at then send that to the browser...
System.IO.MemoryStream memStream;
byte[] bytBuffer;
Response.Clear();
Response.ContentType = "image/png";
memStream = new System.IO.MemoryStream();
bp.Save(memStream, System.Drawing.Imaging.ImageFormat.Png);
bytBuffer = memStream.ToArray();
Response.OutputStream.Write(bytBuffer, 0, bytBuffer.Length);
Response.End();
My C++ skills not good, this is a translation of the VB.NET code that I use..

Use cookies for this kind of problem. Save the user name in cookie on login.aspx on successfull login then redirect. And onload event of login.aspx retrieve the value from cookie

You could store the username in a session variable and then display that information..
<%=Session("Username")%>

Developing a simple service request form with in an intranet...and I need the form to identify the user and automatically fill in the Sent From field when the user submits a request via email from a asp.net 2.0 webform. Please guide me in the right direction.
Thank you.

Need more information,
1) Do you have a source for the email information available
2) Does each user have a unique identification
With this information it may be possible to find a solution.

|
|
|
Their login ID should be unique identifier and email address is provided by exchange server.

I have a custom server control that behave like an image button and a image map. I implement both IPostBackDataHandler and IPostBackEventHandler interface. I place Page.ClientScript.GetPostBackEventReference(MycontrolID, "") on the page's Page_Init() subroutine. I also code all the javascript function. On my test page, I have my custom control and a button. When I click my custom control, my RaisePostBackEvent gets call properly and I got the correct argument passed in from postback. However, when I put my custom control on the content page along with 10 other button and image button, my RaisePostBackEvent no longer get call. Even though my viewstate and control state continues to get process properly. I do not understand why. Can anyone help me ? I have been stuck on this for a week.

Will there always be a hyperlink and it is just a matter of what the link points to? If that is the case you just need to do some custom binding using a Templatefield with a hyperlink control. You can bind the hyperlink properties to the correct values from your data table. Anyway hope that helps.
