Re: Who am I? Detecting the &quot;current&quot; control for a handler

TJoe26-Sep-07 3:22

I would always assume that sender is the control instance that "fired" the event. The form is the one receiving the event. I use the word "assume", because it's really up to the person who coded the control. For the .Net framework controls, I have never seen an instance were sender was not the associated control. If there is then it would probably be considered a bug.

Take care,
Tom

Grabbing the HTML is easy, the rest probably involves regular expressions to parse the string that contains the page.

I'm not sure exactly what you want. If you are looking to get the HTML for a webpage, load it in a WebBrowser object and use the DocumentText property to retrieve the HTML as a string.

If you are looking for the URLs, email, and phone numbers, you'll need to look at the string you got from calling browser.DocumentText for substrings that match the pattern of a URL, email address or phone number. The Regex class is what you might want to look at, since that is *really* helpful at doing pattern matching.

Good Luck!

It isn't enough to do well in life.
One must do good when and where one can.
Otherwise, what's the point?

g.DrawString("abcdef", font, Brushes.Red, new PointF());
MemoryStream mem = new MemoryStream();

BMP.Save(mem,ImageFormat.Bmp);

No, it shouldn't. It should be 54+60*4*32, which it is.

Each pixel uses four bytes, not a single bit.

The bmp file format is not a raw data file, it is an image file format that has a header (in this case 54 bytes), followed by the image data.

Error because of Empty Strings in Method

daniel_v26-Sep-07 1:06

26-Sep-07 1:06

So i have this method, that accepts data inputs of various types from a web form...now some of them (if not all) can be left empty...and thus insert nothing. now my coding is not allowing it to accept these empty strings, any ideas?

This is the coding i am using at the moment;

        protected void Submit_OnClick(object sender, EventArgs e)<br />
        {<br />
            try<br />
            {<br />
                //Insert records in InsertVslLic1() Method<br />
                vesselLicense.InsertVslLic1(Convert.ToDateTime(txtRegistrationDate.Text), Convert.ToInt32(txtMartimeRegistrationNumber.Text), txtVesselName.Text, <br />
                    Convert.ToInt32(ddlVesselCategory.SelectedValue),rblOperativeStatus.SelectedValue, Convert.ToInt32(ddlBasePort.SelectedValue), <br />
                    txtRemarks.Text, txtPreviousAuthorisation.Text, Convert.ToDouble(txtOverallLenght.Text),Convert.ToDouble(txtWidth.Text), <br />
                    Convert.ToDouble(txtHeight.Text), txtConstructionPlace.Text, txtCountry.Text, Convert.ToInt32(txtContructionYear.Text), txtShipyard.Text, <br />
                    txtHullMaterial.Text,txtStructuralRemarks.Text);<br />
<br />
                //Display Success Message<br />
                lblMessage.Text = "Data Input Successful";<br />
<br />
                //Redirect to Page Two [VesselLicense_Page2.aspx]<br />
                Response.Redirect("VesselLicense_Page2.aspx", false);<br />
              }<br />
            catch (Exception ex)<br />
            {<br />
                lblMessage.Text = ex.Message;<br />
                //throw ex;<br />
            }

This is the InsertVslLic1() Method used to input the data in the database (SQL Server 200)

        public void InsertVslLic1(DateTime regDate, int martimeRegNo, string vesselName, int vesselCategory, string operativeStatus, int basePort, string vesselRemarks,<br />
            string previousAuthorisation, double lenght, double width, double height, string constructionPlace, string country, int constructionYear, string shipyard, string hullMaterial,<br />

Most value types in .net 2.0 now have a method called TryParse, this allows you to attempt to parse the string into the value and returns a bool indicating it's sucess.

Here's an example of int.TryParse

First, please use the <pre> tags instead of the <code> tags. It will help the readability of your code sample.

The comment about using the TryParse (or even Parse) is valid, but it doesn't apply to all data types. The DateTime and numeric (Int32, Double, etc.) data types should all have both of these methods.

What is the error you get when you try to insert the data? Have you verified that the SQL statement is correct and that the fields are not set to be non-null in the database?

Scott.

hi!
k, i googled it, i CPed it and couldn't find it..
i've got this code:

<br />
CrReport report = new CrReport();<br />
// do sth with report<br />
int copies = 1;<br />
bool collated = false;<br />
int pageFrom = 1;<br />
int pageTo = 1;<br />
report.PrintToPrinter(copies, collated, pageFrom, pageTo);<br />

my problem is that i want to print all the pages of a report..
so i'd have to set pageTo to value of totalPageCount of the report..
but in the report object i can't find any property that would give me this value..
anyone knows how to get that totalPageCount value?

thx for any help!!

life is study!!!
