Import Dynamic Charts From Excel In Forms?

Apr 14, 2010

I 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.


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.

Excel To Print Charts As PDFs With Image Artifacts?

May 15, 2009

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 (
'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.

Merge Multiple Excel Files Into One Excel File And It Works For 3 Source Files But Its Not Working If Workbook With Worksheet Count Is > 3?

Aug 18, 2011

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.

Creating A Macro In Excel Using Vb?

Feb 24, 2010

I'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


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

Creating An Excel Sheet From A .NET Application?

Mar 16, 2011

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. If it helps, I'm running VB.NET Express 2010 in Windows 7 Home.

Creating Multiple Sql Stored Procedures From .net?

Jun 21, 2010

I'm creating a database installer where I have some code to create database, tables, stored procedures, etc.I don't have problems when creating the database, tables and inserting required data. My problem is when my code gets to the stored procedures section.

Here is what I do:I have different text files (database.txt, tables.txt, insertdata.txt, storeprocedures.txt) where my sql syntax is located.I execute every process/text file using the following:

ExecuteSql("master", GetSql("database.txt")) ' Creating 1 database.
ExecuteSql("mynewdatabase", GetSql("tables.txt")) ' Creating 15 tables.
ExecuteSql("mynewdatabase", GetSql("insertdata.txt")) ' Inserting data to many tables.
ExecuteSql("mynewdatabase", GetSql("storeprocedures.txt")) ' Creating 6 stored procedures.

Here is part of the error:In exception handler: Incorrect syntax near the keyword 'PROCEDURE'. "This is the second stored procedure because the variables I get below belong to the second one"

Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".

When trying to create 6 or even 2 stored procedures using the same file 'storeprocedures.txt' is not possible. If I leave just 1 it works but I really want to keep them together.

Creating 15 tables using the same file 'tables.txt' works, inserting data in different tables using the same file 'insertdata.txt' works.This is the general syntax I use:

Create Procedure sp_stored1
@intVariablex int


Is is possible to create more than 1 stored procedure the way I'm trying to?Do I need to end every stored procedure with specific sql syntax, other than the 'end'?

Creating Settings For Multiple Users

Jun 28, 2011

I have a form which has a textbox named "textbox1", and a button named "Button 1". Button 1 is meant to be a submission for textbox1 (i.e. when button1 is pressed, the value of textbox1 is saved and remembered). I want the value of textbox1 to be remembered on any computer, but I need it to be update-able too. I tried using settings to do this like so:

Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.TextBox1.Text = My.Settings.TextBox1


but the problem in doing this is it only works for the current user. When the application is then put on another computer the value is blank.

IDE :: Creating A Solution With Multiple Projects?

Aug 20, 2009

I thought I'd give VB a go after developing with C# for the past few months.  I'm using Visual Studio 2008 and have imported the VB IDE settings. I'm going through the same steps in VB as I've gone through in C# to create my solution for an n-tiered ASP.NET web application, but the results are unexpected. Here's the steps:

1. File > New Project > Other Project Types > Visual Studio Solutions > Blank Solution  .... name the solution & choose the location ...

2. At this point, I want to proceed to add projects as follows by right-click on the solution in solution explorer

a. Add > Visual Basic > Web > ASP.NET Web Application ... name / location of the Web Client

b.  Add > Visual Basic > Windows > Class Library.. name / location  of the Business Layer

c.  Add > VB > Windows > Class Library ... name / location  of the Data Access Layer

BUT, as soon as I complete step 2a, the solution disappears from solution explorer.  "Show all files" is selected. This happens regardless of the project I create first.
