View 2 RepliesI have successfully created excel application, workbook, worksheet and graphs in excel through vb.net, but I am not able to choose which data to plot on teh x-axis when I plot graphs.I don't really know how to do this even in excel itself, and googling did not help at all...how to create a graph with desired values on the x axis in excel through vb.net, that would be nice.
range1 = Data.Range("A1", "B" & (t2 - t1) / i)
graph1.SetSourceData(Source:=range1)
This is my code, since I have index (t2-t1)/i as the index of the data I want to plot on the y-axis, and I want to plot all A1 values on the x-axis.
I have a form, with a tab control, which contains two different graphs. The graphs work fine, however, i want to be able to switch between the tabs, and be able to see the graphs!. Unfortunately, it seems to clear the graphs. Please can guide me as to how i could fix this.

Tabpages: Using a button, how do I go from tabpage1 to tabpage2? I have it kind of sorted, only not: Button click tabpage1 send to back() or hide() tabpage2 show() The problem with this, is it does not actually turn the page, and the tabpage1 tab still shows at the top. Decimals: Epically basic, I guess. I have calculations that does, for example: 10/6 = 1.666666666667 How do I get it to say 1.667 only?
And Lastly, Graphs: I have a line graph. I have fixed series as a envelope for the variable series to sit in. Again, epically basic - How do I make a series that draws a line for a variable?
I am using vb express and want to display graphs for the data displayed in listview through queries. For example I display data in Listview with the following query:

I have downloaded Ms Charts for vb.net. How I can code to draw the graph of the result of above query displayed in Listview .
This is one of my first steps into the magnificient world of visual basic. I looked on many forums, but most of the time the questions asked are much more complex than mine. I am looking for a piece of code for the preparation of multiple graphs in excel 2003.

Recently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?
basicaly i'm on a project which involves generating programs on the fly from a website, these programs will have the ids of the logged in users.To do this, I found a little trick, which is having a vb.net program running on my windows server communication with my website's database and generating another executable then send it back to the client.Anyway this is just some boring introduction, basically my question is how can I generate an executable from my vb.net executable?
View 6 RepliesI created a project using Visual Studio 2008 Express and I use the Menu tool called Build. There are two selection for the express (Build and Publish).I used the Build and found an .exe in the "bin" folder and the "Debug" subfolder. I am able to double click this .exe file and the program executes.
If I move this .exe file to 2 levels up on the directory, the .exe starts with my (modal form) and then it hangs. how I can make an .exe file that would execute in a different level?

View 5 RepliesYou see three buttons which all contains a one digit number (1, 2 and 3) at the start of running a program. There is one other button stating "Randomize" and when you hit this randomize button all the three buttons that were first containing 1, 2 and 3 are now shuffled in a random order like 2, 3 and 1. In fact, when clicking the randomise button the figures will stay between 1 and 3.I was hoping to sort this out with the following code but it didn't actually work at all:
Dim a, b, c, d, x As Integer
a = Button1.Text
b = Button2.Text

I always have a problem with dynamically generating WHERE conditions to a SQL statement which are base on the nformation given by user (combobox, listbox, checkbox etc.) Here`s an example of how I normally deal with the problem:

Create a GeneratedNumber application that stores in an array with indexes 1 through 100 numbers generated by the index values when Generate is clicked. Generate the number to be stored at each index by summing the index and it's individual digits. For example, 25 should be stored at index 17 because 17+ 1+ 7 = 17 and 4 should be stored at index 2 because 2+ 0 + 2.
Your program should use a FillArray() procedure to generate the nuymbers and DisplayArray() procedure that displays each index and its element in the list box.
