I am trying to develop this application Using Visual Basic 2008. I hope I am posting my question in the correct forum. (Still confused about the difference between VB.net and Visual Basic) Anyways....I am trying to assign the data from my datagridview to a matrix. I donot know if this is possible in VB2008. The data in my datagridview is dynamic and I am trying to assign 2 matrices to my data.[code]...
View 6 RepliesI am trying to display my data in datagridview. I created a class with different property and used its list as the datasource. it worked fine. but I got confused how to do that in case we have nested class.My Classes are as follows:
class Category
property UIN as integer
property Name as string
[code].....
I have a matrix:
Module Procedimientos
Public Datos(200, 4) As String
Public Sub Inicio()[code]....
It is a Class made with the Add Windows Forms Menu.I have another Form where I added from the ToolBox the DataGridView Item.
Everything till now works like a charm, the problem comes when I try to load the matrix (previously posted) into the DataGrid. I search for the matrix via DataSource Button (from DataGrid's Properties) but I can't find it, it'll only show up the other forms. I don't know what I'm doing wrong.
here i am again asking for you assistance. what im trying to acheive is a datagriview that behaves like a matrix.ie. i have the following table
ProductName, ProductRegion, ProductType
Test1, RegionTest1, TypeTest1
Test2, RegionTest1, TypeTest2
Test3, RegionTest1, TypeTest3
Test4, RegionTest2, TypeTest1
Test5, RegionTest2, TypeTest2
what i need in output is something like the following:
<...........> RegionTest1 RegionTest2
TypeTest1 Test1 Test4
TypeTest2 Test2 Test5
TypeTest3 Test3
p.s. i would also need to be able to save it back to the database p.p.s cross posted on "vb dot net forums". but no replies in a while so im posting the same question on this forum.
I'm going to start with a program, and give away bar codes, that they import, then unlocks something.
View 2 RepliesI define 3 arrays: ID(n), Hour(n), Showed(n). If Hour(i) = actual time, I get the data pointed by ID(i), if not Showed(i).
BUT... I can add new hours or modify some existent, but I need to have the Hour array sorted. If I sort this array, the ID and Showed will point to different data.
So I though some different solutions:
1 - To make a string array with all inside (a 7 characters ID, a 5 characters Hour and 1 char for showed (T or F)). It could work, but, how can I sort the middle part of the array (Hour)? So, this don't work.
2 - A 3 dimensions "multitype" matrix (1 dimension of type Integer, the second of type Date and the third of type Boolean). I have no idea about how this can be done.
3 - A 3 dimensions string matrix, some like the "all inside" array: ID converted to a fixed size string, hour converted to a 5 chars string (hh:mm) and Showed converted to T or F. And sort the second dimension.
4 - Sell my copy of Visual Studio and drive a taxi cab
how to build it and how to manipulate it?can i use the data of an access file table as a matrix directly?
View 8 RepliesYpos = TopMargin + Count * PrintFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())
Count = Count + CInt(ROData(x, 4))
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.

After user entered a value into textbox (for example 4), datargidview must be create automatically(number of datargidview's columns and rows must be textbox value). And, user enter some values that among 0 and 1 into datagridview's cells. So i want to assing these values (values that are written in datgridview cells). For example, if user enter 0.25 in datagridview's cell 1, and 0.34 cell 2, 0.67 cell 3, and etc, in this instance array(1,1)=0.25, array(1,2)=0.34, array(1,3)=0.67 must be assigned. i hope, i could understand :) i illustrate this example below. i want to assign such as indexs that is written into following example table.

View 5 RepliesBasically, I want to create a timer for each row of data that will get returned by a SQL query:
SELECT * FROM Projects
I would want the timers to be called "Compteur" & ROWID. This really is necessary.I need them to have different Ticks and so that some can be enabled all at once. Basically it is for a project tracker to count the time you are working on the current project. However you could indeed work on many project at the same time.
I am studying crystal report with visual studio 2008. I knew OLEDB, ADO.Net And ADO connections etc. But whatever connection that we must assign data sources. I want to non-configured and assign data sources as like data-grid. In the data-grid, we can configure data field name and generate data assignation in runtime. Can I do this for report or not. If I can this, tell me how can I do this.

I've been looking into this problem for a few days now and i can't find exactly the code that i want.I want to run a procedure using an incrementing matrix. If the Matrix that was used is correct then the correct matrix is shown.
the process is get first iteration process if incorrect repeat with next iteration correct end the issue is with the iterations and breaking out of them the matrix length, depth and iteration step can vary.
this is best shown in an example
length = 5
high = 3
low = 0
