strFilePath = Directory.GetParent(strFilePath).ToString();
strFilePath = Directory.GetParent(strFilePath).ToString();
strFilePath = strFilePath + "\ACH" + "/ACHFile.txt";
StringBuilder sb = new StringBuilder();
StreamWriter sw = new StreamWriter(strFilePath);
if i browse for a text file and displays it in the text box and trying to save it as the name provided above i am getting the error as Directory Not Found Exception.
Im trying to resize an image. I have the original file and then try to resize it and save it to a new image.However, I get an exception because the value of stream cannot be null. This makes sense, but I dont know how to prevent it:
Value cannot be null.
Parameter name: stream
Description: An unhandled exception occurred during the execution of the current web request.

Using try, catch finally, and end try, what is the best way to display informaiton out of the exception.
View 4 RepliesI have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!

View 2 RepliesWhat would be the best way to catch exceptions and display a detailed message in ASP.NET? I know in regular windows development, you can use an MessageBox.Show(ex.Message) to display the error details. How is this possible in ASP.NET? Is there an example out there someone could direct me to? I have not been able to find anything yet.
View 3 RepliesI am creating web page with similar functionality as the discussion section under each article in codeproject. For example when a person wrote a comment about an article, it creates a hyper link. This can be clicked by another person to add his/her own comment and so on. The problem is that clicking on the hyperlink opens another page, with input controls such as a text box for subject, a text box for content and several check boxes for different options, where once could enter a reply. I would like these controls be part of a webcontrol or a form and open within the page of the article itself and when the save button clicked, it posts the values to be saved, and the controls disappear.

View 1 RepliesI am using a SQL DB to save and display a simple collection of data which contains several dates. As the intended audient is UK based, I wish to display the dates in a UK format (DD/MM/YY). This works well (using {0:d}) and the display and creation of records also works fine.
However, as all fields are editable, when the record is displayed in the Formview edit mode and saved, the dates field try and save in the UK format and will more often than not fail with an invalid date error. How can I display the date in a UK format yet get the same field to save in the usual SQL date format?

I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.

And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
I am trying to build a site that will display a word ("Synset" in my code) from a "function call", (ultimately the word will come from another database but I'm ignoring that part for now). The user will click one of 4 radio buttons deciding if the word is "positive", "negative", "neutral", or "can not be determined". Then the user clicks "Save" the word is saved a MS SQL database, the function is called displaying a new word and the process is repeated.
So far I have been able to get this to mostly work by using the code below. The problem is that the function is called and the correct word displayed when the page loads the first time, when I click a radio button and then the "Submit" button, the word and value from the radio button are saved to the database but then no new word is displayed. The text just disappears. The new word is created, as I can see that new words are saved to the database when i click submit.
I'm thinking the issue might be because I'm binding the text attribute of the label I'm using to display the word to the sqldatasource, because it's probably trying to display the text from the database?
I've tried putting the code that gets and displays the new word in FormView1_PageIndexChanging() and submitButton_Click() and neither work.
I've tried to just call Response.Redirect("Default.aspx") in submitButton_Click() and this displays the word but nothing is saved to the database.
