My problem is when the new data comes out from the API, if it is equal to the previous data and it will appear 0. But what i want is the new data comes out is 0 and it will equal to previous data. e.g: first data comes out is 12.00, in above case, if the second data comes out is 12.00 but it will shows 0 which means unchanged. But in my case now, i want if the first data come out is 12.00, then if the next data is unchanged (0) and it will appear 12.00 and so on.

how to display data in grid view using code that you can edit, update and delete the data...do i need to have a stored proc in this?
View 4 RepliesData binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
I'm trying to take a picture from my webcam when the user clicks a button on a Form on a Windows XP Machine.
I tried going through several threads, but couldn't find the solution I was looking for. Most of the threads involved matters (and code) too complex for my requirements, or had bugs when I reproduced the code in my editor window which I was unable to resolve due to my lack of knowledge in I/O related programming.
So far the simplest solution I could find was this one:[URl]...but after using his solution in my editor, it says 'type WIA is not defined', despite adding a reference to Microsoft Windows Image Acquisition 1.01 Type Library.
I have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.

View 7 RepliesI'm creating a database for photos'.
The issue is that I have a need to upload a set of photos to the database instead of a single photo.
This would be all fine and dandy if I knew how many photos would be added at once but in this case it could be 1 or 100.
I have my database (setup in details) and dragged onto my form. Right now I only have a picture box for my picture to place into the database.
So what's the best way to upload numerous photos to a database without having to create 10000 cells in my database?

View 1 RepliesI've searched the forums for this, but I can't seem to find exactly what I am looking for. I have a form currently that allows me to open a photo in a picturebox. I would like to add functionality that would allow the user to click on a specific part of the photo and add a point overlaid on the photo. This point would be the graphical representation of comment that they will enter in a separate text box. I am stumped on how to even start to get this done.
