I have a tab control with two tab pages. One page has the auto scroll enabled since there is to much content in the page. The middle mouse wheel doesn't scroll the scroll bar; I have to actually click and hold the scroll bar and drag it down to scroll. Is there a property to allow this?

The problem is that this works perfectly if I use the left and right arrows and it also works perfectly if I use the scroll bar's slider SLOWLY. If I scroll using the slider and move it quickly then the scroll gets out of sync.The small change and large change are both set to 1 and maximum is set to 8
I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.
View 1 RepliesI am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.
View 4 RepliesHow would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.

View 5 RepliesIn VB.net 3.5 SP1 I have a Windows Form with three DataGridView controls. One DGV takes up the whole bottom half of the form. The other two share the top half and are side-by-side.
I'd like to have each DataGridView scale appropriately. More specifically I'd like to have column widths and row heights adjust to the size of the form. Then I'd like the cell font to auto-fill based on a change in the cell size.
I've used the Dock property for the controls to scale to the size of the form. How can I get the rows and fonts to utilize the increased form size?
On the Y-Axis of a bar graph, how can I display descriptions as the scales instead of numbers? I don't see anywhere that I can do that.

I need to draw a world map. I got necessary coordinates.I can draw it on a picturebox. To zoom in/out, I multiply the coordinates by a scale and draw them on the picturebox. At the same time I change the size of the picturebox according to scale.Now my problem is, it seems that the picturebox has limitations in size. I can't make it bigger than 32767.

View 2 RepliesI have a digital weighing scale I need to connect to the PC using RS232 communication port.

The control has a serial cable to communicate with.I am trying to figure out what command to send to it to get the weight back.I have connected to it with a serial monitor and i dont seem to be getting any information back so thought maybe I had to send something to it.Right now we have a 3rd party dos program that is communicating with it that i dont have the source to.
I dont know if i could just bypass the control and connect to that serial cable or not,,, i would need to find an adapter if so.Ok probably shot in dark but thought what the heck this is a smart group
I toying with a project where I can position objects runtime on the screen. I also have an small "preview"-window, where I want to see the outline of the objects.I have an object array who have size and location on the "scene". Now I want to loop through my scene-objects and create one picturebox in the preview-window for each object in the "scene".
So, I have the size of the "Scene" and an array of the objects that are visible on the scene. Every object have an size and location mapped to the scene.I also have a preview window that have an dynamic size. How do I create a preview that scales down to the preview window? To make it easy, I loop through the scene objects in the scene and create a picturebox on the preview-form for each object, that uses the preview-forms size to do the scaling.

What I have managed to do is currently display a chart with 3 bars on it linked to textboxes what have numerical values in them when the form is loaded. i.e TextBox1 has an initial value set in it's properties of 10, TextBox2 has a value of 20, TextBox3 has a value of 30.
When I run the program the graph displays these values correctly.
I have also got a button, Button1 which when pressed will plot the chart again, (so if I manually change the values in the TextBoxes after the form has loaded), it will display the new values via the bars.
The problem I have is that if if once the initial values have been plotted when the form loads, i.e. 10, 20 & 30, the Y axis of the chart has a maximum value of 35, so that all the initial values for the bars are shown. But if I change the values to say 15, 30, 80. and then press Button1 to update that bars to thier new values, the bars change but the one that show's 80 can not been seen fully as it goes off the chart, as the Y axis still only shows a maximum value of 35!
Does anyone know how to get the chart to resize to be able to display all the bar values within the chart each time the values are changed and the Button1 is pressed, whether it be reducing the graph for smaller values or enlarging the chart for higher values?
I am not 100% sure I am going about it in the correct way as I have not got any experience in using charts and am having to stuble about the net trying to find basic example code of how to setup and use a chart
