FileUpload.FileContent empty after first iteration of loop

Posted By:      Posted Date: October 05, 2010    Points: 0   Category :ASP.Net

I think this is something really easy that I am missing.  I have a loop that is sending emails.  The loop adds an attachement from a FileUpload instance.  The first run of the loop is fine but each subsequent run the attachment is empty.  I have found mention of reseting contentstream.position to 0 but that doesn't seem to apply to the FileUpload control.  I am attaching the code below if anyone can give me some suggestions.  Thanks.

        //cycle through all loaded email addresses to send email
        foreach (string s in parentEmailArray)
                //from, to, subject, body
                System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage(emailFrom, "", subjectText + " [" + s + "]", emailBody.ToString());
                //System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage(emailFrom, s, subjectText, emailBody.ToString());
                mm.IsBodyHtml = true;

                //TODO: add attachment if applicable
                if (!string.IsNullOrEmpty(this.uplEmailAttachment.FileName))
                    System.Net.Mail.Attachment att = new System.Net.Mail.Attachment(this.uplEmailAttachment.FileContent, this.uplEmailAttachment.FileNa

How to go to next iteration of ForEach Loop container on task failure

I'm using a ForEach Loop container to iterate through a set of files and import/validate the data.  Within each loop, the first thing that happens is that I fill a variable from a table and then use a script task to make sure that the rest of the package should be run for this particular file.  If it should continue, I set Dts.TaskResult = Dts.Results.Success, and if it shouldn't, I set it to Dts.Results.Failure.  My question is, how do I get it to exit the current iteration of the loop and continue to the next iteration?  The way it is now, the package just stops completely.  I set the FailPackageOnFailure property to False for the script task, but that doesn't make a difference.  I also tried pointing a failure precedence contstraint bacl to the loop container, but that's not allowed.  How can I make it just continue in the loop?   Thanks.

Microsoft's Collaborative Application Markup Language (CAML) Loop

discovered an interesting error recently while working with Microsoft's Collaborative Application Markup Language (CAML) that, surprisingly, had received no ink. Partly what surprises me about this is that the error may require you to rewrite large sections of your code if you haven't previously considered this SharePoint limitation. I'll start with some context, but first of all the error is:

Server side validation of Fileupload control not working



I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.

How to check for null/empty strings on dynamic objects?


What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:

if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)

If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?

Add an empty line in Gridview on specific dayofweek


Hey all,

Havin quite a bit of trouble with this one.  I have a bunch of days that I worked in my database...mostly monday-friday and some saturdays.  What I want the gridview to do is add an empty line between each sunday and monday so that it seperates out my work weeks and makes it easier to read in the gridview.  I got some help here a few days ago on how to clone the db etc and I have all that working properly but I can't seem to wrap my head around how to do add these empty lines in the proper spots.  Here is my code so far:

private DataTable AddEmptyRow()
        DataTable originalDataTable = GetItems();
        DataTable newDataTable = originalDataTable.Clone();
        DateTime testdate = Convert.ToDateTime("7/20/2010");

            for (int i = 0; i < originalDataTable.Rows.Count; i++)
                DayOfWeek day = testdate.DayOfWeek;

                if (day == DayOfWeek.Sunday)
                    DataRow newDataRow = newDataTable.NewRow();



Empty Website Data Source windown


Hi all,

I am Visual Web Developer user and facing a problem when I am creating a local report (.rdlc) file.

I am using Business objects as the Data Source for this report. It was working perfectly until all the items in the Website Data Source window suddenly "disappeared". The "Add New Data Source" button on this window is also disabled. Now the window is just like a blank box only. And I can't continue working with the report file like this...

I have tried undoing what I did before but it does not help at all...

Any reason for this to happen? There is no sign or something at least indicating what is wrong.

Please help.


 ps: found a similar thread in this forum but not solved

Datalist with embedded Grid or List...Sub Totals issue with iteration


Let me see if one of you can assist with this one...


i have a similar situation, but mine does not use the selected item (item Command). Here is what the form is to do:


1. this is for an educational environment, so we use SID- NOT SSN's, but i use the SID as a filter in the subset as the grouping unique id.

2. I'm trying to inject a sub total row at the last line item of each SID (if more than one item in the report for that SID).

3. I'm looping thru the items in the Datalist Item Command with a for each (item i in Datalist2.Items).

FileUpload Class SaveAs, how can you overwrite?

Hello all,

I'm trying to use 2.0 class, FileUpload. 
Namespace: System.Web.UI.WebControls
Class FileUpload

Anyway, in my code can save the file to the server

FileUpload1.SaveAs(SavePath + FileName)

Problem is I can't find a way to overwrite the file.  When I try and run the program again is says the file is already in use that a process has access to it.

Is thre a proper way to release control of whatever it grabbing hold of it?  In .Net I don't have to destroy my objects right?
Or is there a way to specificly overwrite the file? It seems that SaveAs does that.  Just trying to figure out why I can upload this text file, but sometimes only once and then I have to code in to check to see if it exists then rename it.

FileUpload error: Object reference error


I have a FormView with a FileUpload to upload an image in a database.

I keep getting an object reference error.(view code)

I am using this same script to upload the image to the database, but when I try to update the file upload I get the error.    

string strFilePath=Server.MapPath("\\images\\"+fupdImage.FileName);

        Byte[] image=null;
        HttpPostedFile imgVid=FileUpload.PostedFile;

        image=new Byte[imgVid.ContentLength];//Object reference not set to an instance of an object.

        if(FileUpload.HasFile) {

        string fileFormat=imageFile.Substring(index+1);


Loop for every record


Hi guys.

I've got a simple table with an ID, a NAME and an ARCHIVE booleen.

I want to write piece of code that goes through each record and...

If ARCHIVE is false and a folder hasn't been created for it, it will create it and go to the next record.

If ARCHIVE is false and a folder has been created for it, it will do nothing and go to the next record.

If ARCHIVE is true the whole folder will be moved to another folder and go to the next record.

When all records have been checked, the code will end.

I was thinking of using a SQL count to find out how many records there were and making a loop that starts at record one. runs the folder checking/creating/archiving code then +1 until the loop ends but I couldn't work out how to assign the query results to an integer...

I'm not asking for anyone to write the code. I think I probably already know 80% of the theory behind doing this I just can't glue it all together. I know you can do the folder stuff with the System.IO Directory Class...

Anyway, all input is welcome. Cheers guys!

Dropdown menu - Null or empty string??


I have drop dowm menu as follow.

<asp:ListItem Value="">none</asp:ListItem>
<asp:ListItem Value="STO">Stock</asp:ListItem>
<asp:ListItem Value="ORD">Order</asp:ListItem>

If I chose none, it stores data as "Null"

If I Query the data as below, I don't get the data has value of "Null"

SELECT tabale From type Where type <> STO or type <> ORD

I get data that has empty string but not Null.

Here is my question.

1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.

2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD

Thank you for your help.
