I'm trying to create multiple Excel charts, in one work sheet using VB.net.This is the code:
Code:
'creating the chart
Dim chartPage As Excel.Chart
Dim xlPump1Charts As Excel.ChartObjects
[code]....
Is there a way to conditionally format an Excel Chart? For example I have a bar graph. Currently I have the bars a purple color. I would like to turn a certain bar red if it meets certain criteria. Is there anyway to do this?

View 4 RepliesI am using VB for developing a GUI. I need to display charts in the VB form. How do I invoke Excel 2003 using VB and import the charts created in it.
Steps:
1) Getting input from the user using VB form and processing it in VB or external application such as Matlab.
2) Over-Write the processed data in excel sheet.
3) Modify the charts based on the new data which I believe will happen automatically.
4) Display the chart in the VB form.
I have an Excel 2007 workbook chock full o' VBA macros that do various things, including one that jumps from chart to chart making PDFs of each using PDFCreator, based on some code I borrowed from Ken Puls (url...).However recently I and some users of the workbook started having problems where the PDFs would be created with either gray image artifacts over the charts,or the whole chart image would have a double of itself skewed slightly. It just happens the problems started after we did a global upgrade to Office 2007, though I had had 2007 installed on my computer for a while and tested and used the workbook extensively without issue up until then. Here is the part of the code that automates the printing:
Sub PDF_print_all()
'Author : Ken Puls (www.excelguru.ca)
'Macro Purpose: Print to PDF file using PDFCreator[code]...
The problem is not consistent either... sometimes it will print to PDF with an oddly shaped block of gray, and sometimes it will only have the whole chart image doubled. The only consistency I could find is that sometimes if an object is selected in a chart beforehand (a text box, chart line, axis numbers, etc) the gray artifact will partly mimic the shape of whatever object had been selected.I wish I could include example images to show exactly what's happening.I know it's not a problem inherent to PDFCreator because if I manually print to it in Excel, the PDF image looks perfect. It's only when I use the automated method that the problem occurs, so I thought maybe it was the code.

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

View 1 RepliesI'm creating a macro in excel using vb?What the macro is doing is checking if the row and column headers are same, and if it is then I want it to save the row header (the date in this case) AND the value (a number) into an array, and this is done in a for loop and goes on.... I dont know if I should use 2-D array or a 1-D array that stores 2 values....Not sure at all !Then after the outer most FOR LOOP is done, I want to print those values stored in the array.
Here is what I have so far, this works actually however i'm using 2 seperate arrays, one to store the row header (the date) and another array to store the value. But really I want to make it simpler, shorter and use only one array that stores both of these values as we go through the for loop and at the end of the for loop, all the values from beginning which are stored can be printed out.
Here is my code :
Sub Test ()
Dim sys_arr() As String ' declaring the array to store the values
Dim sys_date_arr() As String 'declaring the array to store the dates
[code]....
This totally works but with 2 different arrays, all I want is just 1 single array (not sure if it is 2-dimensions or still stays as 1 dimension but with 2 different variables)... and then the array can store the date and variable correspondant to the date, and goes to the next row, and do same thing... So the output results should be like for eg :
2/12/2010 37
2/13/2010 41
2/14/2010 66
and so forth

I have a pet project of mine that I'm working on; basically, it's for scouts during FIRST FRC matches and allows them to enter data about teams into an Excel sheet. I'm having a problem creating said sheet, however. I want the program to create a new sheet, with the filename being whatever the user puts in a textbox I have. the interface takes data about teams one team at a time; when user wants to add a new team, they press "Enter Data" (which puts whatever is in the interface on Row x, then the user will be able to add new data to Row x+1 each time they press said button, etc). The main issue is that when I have the code as follows:

I've narrowed the problem to the "filename" and "filepath" variables. I've Googled around for answers, but the articles that I found about the error above are too vague to help me. Does anyone know why VB.NET is giving me this error? Also, how can I reuse the same Excel sheet for the entire duration that my VB.NET application is running? As in, I want to be able to add ~50 or so teams to the same Excel document (for example, all of it going into "MyRegional.xls").
Sorry if this is an obvious problem to solve or anything; I'm fairly new to programming in general, so I'm clueless as to what's going on with this. Up until this point, my program runs fine and when I comment out "Dim filename..." and "Dim filepath...", the program will run normally.

ExecuteSql("master", GetSql("database.txt")) ' Creating 1 database.

ExecuteSql("mynewdatabase", GetSql("insertdata.txt")) ' Inserting data to many tables.
