VBA In Excel - Tag 24 Integer Variables And Put Them All Together In One Cell
Jul 1, 2009
[Code].....
I am writing a VBA code for testing different combination of 24 variables and recording a result which corresponds to each combination of 24 variables. so I have an equation with 24 variables and one result. In excel I have one column which contains the 24 variables and the column next to it contains a figure which shows the result. what I need to do is to write loops to change the 24 variables between 1,2, and 3 and then record the result of the equation for each combination of 24 variables. I have written the loops (24 loops) and can record the result for each combination, what I have to do at this stage is to record the combinations which relates to each result.
As there is only one result for each combination of 24 variables I was wondering whether I can tag each variable (in each cell) in a way that in the final sheet in the cell next to the result cell I can write for example 111123123111233311121232. This means that after each loop I am taking the values for each variable in 24 cells and put them all together in one cell in the final sheet. These variables are changing in each loop, the label should change as well after each loop so after the completion of the code I can find out which combination relates to which result. I have tried to define an array or matrix but I couldn't fix the problem. This is the input sheet (the code changes the values in the cells in A column after each operation)

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

I would like to update an Excel cell using the cell name, such as "A1", instead of using the row and column, such as (3,2). I haven't been able to do it. Here is the code I used to update the cell by row and column. How would this code be updated so that it updates the cell by cell name instead?

I have a program that calculates values of a function, say f, with respect to another variable, say L.I have an array of f(L), for L going from 0 to a given integer value, say t-1 in steps of a value i.I need to export the values of this function to an Excel spreadsheet in a given column, and to do this, I would like to re-index the function f, since i is much less than one, and so the following loop I use (see below) won't work:
For L = 0 To t - 1 Step i
Sheet.Cells(L, 1) = L
Sheet.Cells(L + 1, 2) = f(L)
Next L
The first code in the loop will essentially load the values of L itself, at which the function is defined and calculated, and the next line will load the values of the function at each value of L.Since the indexes of the row and columns in an excel spreadsheet only go in steps of 1, I need to convert the indexes of the function, or the indexes to which L is loaded, so that it would be scaled so that the first entry corresponds to L=0, but the next is L=i, but loaded into row number 2, etc.

I am using the DataGridView in Visual Basic 2008 Express with an Access 2000 database.
What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.

I have a program that is reading an Excel (xlsx) file and I am trying to take the data found in one of the cells and split it based upon the '@' symbol inside that cell. Here's an example: value in cell is "XXX @ YYY" I declare 3 strings (strOriginal, strA, strH) strOriginal is the value from the cell ("XXX @ YYY") then my code is supposed to split up the values in the Original string based upon that '@' symbol.So when my code is done, strA should = 'XXX' and strH should = 'YYY'.
Here is my code
strOriginal = dtbExcelData.Rows(0).Item(0).ToString
y = strOriginal.IndexOf("@")
strA = strOriginal.Substring(0, y - 1)
[code]....
For some unknown reason, the y integer (in this case, it is '4') changes to a random number (it has changed to 44, 61, 124) and causes the error "Error with Excel file: Index and length must refer to a location within the string. Parameter name: length" to occur.I understand why the error occurs (my y integer is not staying at 4)...I just don't understand why that y integer is changing numbers when it should remain as the indexof the '@' symbol. I'm looking for any suggestions on how to pull out the data after the space after the '@' symbol (the 'YYY' portion of 'XXX @ YYY'). Also sometimes the 'YYY' is only 'YY' as well.

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

I am using Visual Basic.Net 2003 with an Access 2000 database.
An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.
1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.
2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.

I am using Visual studio 2008.I have an application that reformats an excel spreadsheet. One of the operations is to copy the contents of the cells from the source to the target sheet. One of the columns has numbers. In excel, if the column is not wide enough, it will display the numbers as "###". For instance, if i have a number 99 and the column is not wide enough, it displays "#" in that cell. The problem is that when I copy this cell to my target sheet, I get "#" and not 99.
