Executing Another .vb Code File From Code Behind?
Jan 20, 2010I just finished building a new version of a web app that imports custom-formatted documents. However, now I just found out that I need this web app to also import custom documents from 3 years ago. I have the code from 3 years ago that imports the older docs...
I was wondering if I could put some type of "if then" statement in my code like " If oldVersionofDoc Then...execute the old code located in this .vb file".

Web Forms :: Executing Code After Dialog Box?
Aug 13, 2010[Code]....
I then decided to run the whole thing on the server it uses the same code above but I now have several parameters to pass in and call a slightly different stored procedure
DataSet dsEx = new DataSet();
SqlCommand testcommand = new SqlCommand();
testcommand.CommandText = "spLockUnlock";
testcommand.CommandType = CommandType.StoredProcedure;
testcommand.Connection = sqlLockUnConn;
testcommand.Connection.Open();
testcommand.Parameters.Add("@OffState", SqlDbType.Varchar);
testcommand.Parameters["@OffState"].Value = ViewState["OffState"].ToString();
testcommand.Parameters.Add("User",SqlDbType.Int);
testcommand.Parameters["@User"].Value = lblUserID.Text;
testcommand.ExecuteNonQuery();
testcommand.Connection.Close();
rest of the code follows
The stored procedure uses the parameters to lock certain records, then I use exec spOfflineSystem which executes a series of select statements (as above), then I unlock the records afterwards....no problems however my dialog box on the front now reads
CustomersEC45TG.xml
If you step through the code the filename reads Customers.xml yet on the front end we get the spurious characters....each time this is executed the spurious characters are different. Only every now and then will the correct filename dialog box show.

Jul 22, 2010I have a Global.Asax and Global.Asax.cs file that is specific to my particular Asp.net project. For some unknown reason the code in my Global.asax.cs file is not being executed. I thought that the breakpoints were being ignored, however that is not the case. Because if I try to deliberately force an error to occur, the code is never executed. Below is an example of what I am talking about. The real code in my Application_Start method is not shown below. ANd other methods are not shown as well.
I have tried renaming the Global.asax file and then re-creating it, and that did not work either. Strange because when I try and create a new Global.asax file, the option to create a code behind file is greyed out.
Why isn't my Global.Asax.cs code being executed?
private void Application_Start(object sender, EventArgs e)
{
int x = 1;
int y = 1;
int z=1/(x-y)
}

Jun 1, 2010I have a user control with a dozen radion buttons in it.Every pair of radio buttons execute a Sub on server side.All of the radio buttons have the autopostback set to true.There is a public Sub of the usercontrol that gets called only once by the page and loads the data setting the radio buttons to checked or not checked.The problem is, that once a radio button is set, it will execute it's server side code on every postback even if the postback is caused by another control on the usercontrol or even another control on the page. So if all the radiobutton pairs are set and a postback is caused, there will be six server side Sub executing! Casting the sender in each of those Subs gives back the radiobutton that is checked at that point, so it's if on every postback the event is fired for each checked radiobutton.

View 2 RepliesWeb Forms :: How To Stop Code Interrupt
Jan 10, 2011I have a repeater and a user control on my page, when any of the items in the repeater are selected this refreshes the user control accordingly. However I found that if I selected another item before the page/user control had finished to load it produced an error, when left to let the page/control fully load and reselect no error.Clearly this is interrupting the code before its finished, can I stop this from happening by doing some sort of check to see if the user control has finished loading?
View 3 RepliesWeb Forms :: Executing A .bat File In Using The Command Line In C#
Aug 23, 2010I'm trying to execute a .bat file in my web page when a user clicks a button. The normal command I would run in the command window is as follows. abc.bat 1 Where 1 is project number which is dynamically assigned according to the scenario in the program. Also the .bat file is inside the folder D:Test1. My code looks like this.....
void CreateProjectData( string strProjectId)
{
System.Diagnostics.Process newProcess = new System.Diagnostics.Process();
newProcess.StartInfo.UseShellExecute = false;
newProcess.StartInfo.FileName = @"D:Test1abc.bat" ;
newProcess.StartInfo.Arguments = "abc.bat " +strProjectId;
newProcess.StartInfo.CreateNoWindow = true;
newProcess.StartInfo.RedirectStandardInput = true;
newProcess.Start();
newProcess.Close();
}
When I run the .bat file the data should be generated for project and stored in a database. When I run this in command line it works fine. But when I run the above code in the asp.net web page it executes without any errors but does not store any values in the database. Have I defined the project name, arguments correctly in the above scenario?

RegisterClientScriptBlock Code Not Executing?
Apr 12, 2010I'm using the following code in an attempt to show a dialog with a list of errors on the client:
if (rollout.ImportErrors.Count > 0)
{
ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true);
}
The error count is non-zero and the following script block is emitted, but the script isn't executing.
<script type="text/javascript">
//<![CDATA[
$("#error-report").dialog("open")//]]>
</script>
If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.
