View 8 RepliesThe object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties

View 6 RepliesI have been learning a bit of jQuery and .Net in VB. I have created a product customize tool of sorts that basically layers up div and add's text, images etc on top of a tshirt.I'm stuck on an important stage!I need to be able to convert the content of the div that wraps all these divs of text and images to one flat image taking into account any CSS that has been applied to it also.I have heard of things that I could use to screen capture the content of a browser on the server which could be possible for low res thumbs etc, but it sounds a little troublesome! and it would really be nice to create an image of high res.I have also heard to converting the html to html5 canvas then writing that out... but looks too complicated for me to fathom and browser support is an issue.I'm thinking perhaps I could do with two solutions for this. Ideally I would end up with a normal res jpg/png etc for displaying on the website, But also a print ready high res file would be very desirable as well.
View 3 RepliesWhat I am attempting to do is make a form for a tire shop. I want to put comboboxes on the left side of the form that the employees make choices from. I then want to put some kind of a table or grid looking thing on the right side of the form that will display their choices so that everyone in the shop can look at it see that "John is on bay 5 until 3:00pm". At the end of the day I want all of the combobox choices to save to a file..I dont really need the table or the grid thing to save..just the choices. If I want to do this, do I need to use that gridview tool? or can I make my own table thing to display the choices in.
View 9 RepliesI am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

What I need is to take numbers from several textboxes (4 rows, 5 columns) and put them into an array. I was able to successfully do this with the string data, but there were only 5 items, and I'm not quite sure I did that right although it works. I've seen in the book how to get data from input boxes and listboxes but not textboxes. BTW-I've included my code, but this is only from one of the forms for this project.

What I'm trying to do is take a 'input' video file (I can make it whatever file type will make this the easiest) and then, through my code, add text to the video file. for example, it would take 'Sample1.mpg' and output 'Sample2.mpg'. It wouldn't show the video (I've found some tutorials that talk about overlaying text as the video plays; but not actually modifying the video file.
Basically, I'd like to be able to say, 'From seconds 1 to 200, draw 'Hi Mom' at position 0,0 with this font' and have that saved in the outputed video. Whenever you run the outputted video, with any player, you'd end up seeing the text; because it'd be part of the video file.I've heard claims like, 'DirectShow!' but I'd really welcome anything slightly more specific.

with the orginal text i mean the text that is hard coded into the asp.net markup.

This is a big idea and I'm unsure of how easy or difficult this really is. I do not know how I would get this even started. What I am trying to accomplish is "docking" so to speak, a sub form into the original. Basically, there are 2 forms open, but one is like a helper so to speak. This concept is not new as many programs use it. An example is a program widely used call Teamviewer. If you use Teamviewer, open the "Partner List" Pane at the bottom to see exactly what I am talking about. Basically, it opens a new form that is next to it.

I have a program that my boss ask me to add something on it for report generation but this is a finished program. My problem is if I add a script on this program and build and run using the debugger, the IDE will create a duplicate of my class and will read the original script. I copied the program and place it on a different drive so as I will still have a back-up of the original program at drive c:. And I tried to copy the program again and put it on a different folder but I still have the same problem.
