I want to find out the X and Y position of a point which is halfway between a point and another point, in VB.net. Since there is no "direction" property (which would make this much easier...), I have no idea how to do this.
C# code is acceptable as well, though I would prefer vb as it wouldn't require a port.
randomizing picturebox location given four points example:i have 4 picture boxes. these boxes should be place at points (145, 190) (210, 190) (290, 190) (37, 190). this will display the pictureboxes at a horizontal line. i'm adding a functionality that when i press spacebar or click a button, these coordinates will be randomized and be assigned to my four pictureboxes just like in text twist but no animations.

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

Is there a way of converting pixels to points? The dimensions in VB are in pixels, but Office COM such as WordApp.Resize are expressed in points. So trying to align app windows is a mess.I guess the ratio of pixels to points varies from one monitor to another(?), so this would need to be calculated at run time.I tried a nifty trick of doing Me.Font.SizeInPoints / Me.FontHeight but that doesnt seem to be quite right or a very sensible way of doing it.

I'm building a card game called 11-UP. See the game here.I've gotten to the point where I need to make scores show up when the selected cards have a sum of 11. For example, if the card is worth 200 points, then "200" should become visible for about a second and then "float away".
I know I can do this with a timer and the location property. I was thinking of creating an array of 22 timers, one for each card. When the selected cards have a sum of eleven, I enable the timers for each selected card. The timer makes the "score" for that card appear, then move up a few times, then vanish.
Does anyone have a better way to do it? Maybe with only one timer?Also, how could I make the "scores" become more transparent as time advances? I'd like to make them not only float away, but also "disolve."

I have a very long list of points I would like to plot on any state in the US. I would prefer to plot each point with just a dot. All I have is an address that includes the street address, city and state and possibly the zip code. Ideally, I would like to place the resuts in a VB Picture box. I understand there is a Google interface but have found in my research the examples to be lacking exactly what I need.
View 3 RepliesI have a general idea of what the code should look like but I can't seem to finish/put it together.I have a year's worth of data such as December 01, 2010 to December 01, 2011.The problem is that there are more than 365 points, some days for example have 3 data points and others have 4, etc..What I would like is to only have 365 points of data by averaging the data points for the days that have multiple points.
[Code]...
- So far I have another column with dates from Dec 1st 2010 to Dec 1st 2011.
- I think I'll need an IF statement for if the whole range of A column equals one of 365 days, it'll equal the average data.
- then I'll need to have a statement for x+1 date for each consequtive day.
