If you have added them with the doubled extension and there really are hundreds of them, write a script to get all images in the folder and rename each one in turn (taking the file name part, ignoring the extension, and checking if it contains .jpg. If it does do …

I've found the related article, while it maybe sometimes relevant (but not always), is hardly ever very timely. Often they are articles from months or sometimes years ago. This maybe relevant to the poster, to find other articles related to their question, but as I am in the process of …

Can't you pass in the points as one data set rather than call it 16 times? You'd need to change your plotting function of course. How fast are new plot points generated (can you slow down the function call to match the incoming data)? If it becomes unresponsive when use …

The most obvious answer is that the user name is the student ID. If you don't want to do that and instead have a different login name then you will need another column in your student table that stores their user name. Then you use the user name in the …

Simply drag two dateTimePickers onto your form, one for the from date and the other for the to date. You can then access the DataTimePicker.Text method to retrieve the value of either one. E.g. some simple code to get the days between two dates Dim date1 As New Date Dim …

It sounds like your class definition is incorrect. You would have forgotten a { or } somewhere and so your class or methods don't properly close. A sample class would look like this: namespace SampleNamespace { class SampleClass { public void SampleMethod() { System.Console.WriteLine( "SampleMethod inside SampleNamespace"); } } } …

How does the information relate to the other fields and the gridView? You will need to construct a database with at least one table (maybe more depending on your answer to my first question) to hold the info. You haven't mentioned whether you have done that yet. After that the …

It looks like your containing div (with the pink background has a set height to it. The text you added pushed the content beyond that height limit. You can change the height of the div to something like height:auto (so it is always just as big as it needs to …

Obviously the connection string you are using will have to change and hopefully the dev team knew enough to store it in one place only (web.config). You can find the connection string syntax for MySQL at connectionstrings.com. Also, in certain places you may need to alter the actual SQL commands …

I'm with Momerath here. Just out of curiosity what use could 16.7 million rows be to anyone? If you need to proceed what you need to do can be done with nested for statements, three of them, each one holding one of the sets of 0 to 255. Then just …

You are missing some syntax somewhere in the class, most likely a method that has no End Sub.

You can simply redirect to the MyAccount page and then it uses the session value to load the appropriate data. If you are going to another page in your own site passing a session variable as a parameter in the URL is really not needed.

The best way (if it is a compiled, dynamic site, rather than static HTML) is host it somewhere and give them the URL. You can't expect to send them the files and have them install IIS and a database just to view it.

Are intending to use Crystal Reports for it or do you want a simply, ad hoc solution (coding yourself)?

Debug your code and step through it. That will help you find the exact section that is causing problems. And this was really hard to read. You should get in the habit of using either pascal case (PascalCase - capitalise every first letter) or camel case (camelCase - capitalise every …

I just read these two books on C#4.0 and found them to be very good. They might be a little advanced for a complete novice but they go into depth on a range of topics: Programming C# 4.0 Ian Griffiths, Matthew Adams, published by O'reilly Fluent C# Rebecca M. Riordan, …

LinkButton.Text = "Like"; You will want the code to check the current text of the button so it knows what to change to I guess. An if statement will do that easily enough: if(LinkButton1.Text == "Like") { LinkButton1.Text = "Unlike"; // plus whatever other codes runs when something is liked …

You are calling your cmd.execute twice, once to execute it and again to ensure it worked and clear out the textboxes. That is where the duplication is coming from. Remove the first instance and the second will run and provide you with your check that it succeded at the same …

You can call Process.Start() to start an executable. E.g. Process.Start('notepad.exe') will fire up notepad. Your text is only appearing the top textbox because that is all you are telling it to do. If you open a file and want the text to appear in more than one textbox, first store …

For HTML emails the images always need to be used with an absolute path. src="image1.jpg" means nothing when the code is away from your development environment. You will need to host the images on a server and point to them with a full address. This link will help you: http://kb.mailchimp.com/article/top-html-email-coding-mistakes

We would need an actual explanation of the problem first. Does it fail completely or just not look right? And IE6, really? W3C school stats show IE6 is down to around 1% usage now and it was a terrible browser with plenty of bugs to begin with. Later browsers adhere …

Are you wanting to convert a hex color into an image of the same color, a block of that color only? You can use the system.drawing to create an image, brush it with that color (basically filling it with one color and then save it as a file. The images …

Check out how to load a file using LOAD LOCAL INFILE command for MySql or for MSSQL the bulk insert method e.g. BULK INSERT OrdersBulk FROM 'c:\file.csv' WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) Which database are you using and, more importantly, what error are you getting?

The solution is to store the fact that the process ran (or is running) somewhere (database, text file, in memory) and then runReport() checks that value after it determines the time is right but before it starts actual processing.

It looks like you are missing an operator (AND or OR) in your statement. sql = "Select * From Skills Where StampNo = " & Stamno & " Cell = " & cell & " And Op-Number = '" & op & "' " This translates to SELECT * FROM …

Are you having trouble with the SQL query to check if the name is already used? just do a SELECT COUNT() on the user name or email. There should be zero results if the name is unique and 1 if it is already registered. You can then proceed to save …

You can iterate through a repeater using the foreach loop and the findControl() method to search for the control you want to change, disable, etc. You will probably need to run through the repeater to find the row you want to alter (based on whatever makes that row the target) …

Most browsers can be opened with a URL as a parameter using the Process.start() method e.g. Process.start('firefox.exe', 'someURL'). As you will be opening them as their own processes when you do this you won't be able to control where they open (I don't think).

Hi, Don't disable the back button. Instead you should have code in each of your pages (in the page_load) that checks if the session is current and if not redirects to the log in page (or whatever is relevant). There once a user logs out and the session is cleared, …
