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.
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 array of data which is currently updating itself every 10seconds from when my spreadsheet is opened as you can see from the VBA module code given below, that is fine but the charts that I have created manually from the data are not updating themselves as the data changes. When I change the data by editing a number in the range etc. then surely enough the chart updates. Is there any code available which will refresh the chart I have made automatically say every 15 seconds, giving a 5 interval breathing space between the data and chart update?
The code I have attempted to resolve the problem in the Sub AllWorkbookCharts () doesn't work as there is a problem with the refresh part of it.
Sub Update_Time()
Application.OnTime Now() + TimeValue("00:00:10"), "Sort_Table"
Application.OnTime Now() + TimeValue("00:00:15"), "AllWorkbook_Charts"
End Sub
Sub Sort_Table()

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?

Probably a silly question but is it possible in Excel or VB to drag a charts point(s) ?I had a quick look at the object "Points"(part of Series Collection object) methods and saw there was a "Select" function.

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 am trying to import an excel sheet to a sql database. I was able to get it to work using sqlbulkcopy. I am now trying to do it line by line. The code works fine except that only the first row is added to the database. I used a msgbox to ensure that I am iterating through all of the excel values. So I am not sure what is wrong.

I tried searching for someone that has done this, but turned up nothing. I can import an excel sheet to a DGV just fine, but want I want to do is import it row by row so that I can do validation on each field and then if it is ok, put it in the DGV.if I could do it row by row, validate, then add it to a datatable/dataset, then bind that to a DGV.I can't find any example code of someone doing it row by row, only SELECT * which grabs everything and puts it in a dataset.

Everything seems to imports ok until i look at the data in more detail, this is when I notice its imported the data but in the wrong order.
for some reason when I look at the db table all records are in the wrong order, and strangely enough it seems to be a different order every time I import things.
Is there a way to force the routine to import the data in the same order as the it is in the excel file?, because at the minute it seems to have a mind of its own[code]...

I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db.

I'm creating a windows application using visual studio. My code is in visual basic. I want to enter a "Browse" button where the user will click on it and select an excel file from his computer. Then,for each column of the excel file, I want to create an arraythat will contain the same data with the column.Only the first sheet will be necessary and it will have specific number of collumns. I won't know the number of the rows, I will be needing a counter for these as well. My object is to have these data as arrays and to be able to make some calculations.
