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 (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 need to print multiple existing files, PDFs. I have the following
[Code]....
Is there another 'better' way of doing this? Sometimes it just doesn't print the PDF, I guess because it's taking longer than the WaitForExit time. And so closes the process.

I'm using Dundas Chart Profession within my VB program to generate a chart based on my data. Right now I have my charts opening fine but I am unsure how to add the functionality to let the user choose to print (and export) the chart once the program is running.

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 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 a simple VB calculator app with a PrintForm procedure shown below which works fine on my Win7 machine but when I deploy the app to an XP Pro machine it produces artifacts from the MenuStrip where the Print command is executed. Any ideas why this would happen or how I can resolve it? I'm new to VB.net and OOP as a whole so if this is a simple problem.

A simple form with a combobox called Combo, drawing artifacts when using ComboBox with Custom Draw and the contents of the combobox is scrolled up or down, and with this source code, illustrates the issue:
Public Class Form1
Private Sub Combo_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles Combo.DrawItem
Dim Combo As ComboBox = TryCast(sender, ComboBox)
If Combo Is Nothing Then Exit Sub
If e.Index = -1 Or e.Index >= Combo.Items.Count Then
e.DrawBackground()

I've got relatively little experience with VB but I've been asked by my employer to try to write a program to automate a billing process. We print PDFs for some of our clients, and we do two copies. One copy goes to the account holder, and one goes to the company that funds the account. So we have a directory structure that looks something like this:
Copies that went to the account holders:
FolderA1234.pdf
FolderB987.pdf
FolderB6767.pdf
[Code]...
As you can see, the file names are the same. But items in FolderA are billed differently than items in FolderB. So the ideal program would be able to go through FolderA and FolderB, collect the filenames, and then go through SubfolderA and SubSubFolderA and report back that, "1 file matched a filename in FolderA. 2 files matched filenames in FolderB". I have no idea where I would beging to write such a program but is this something that is plausible?
My manager says he can probably do something like this in an hour manually so if it would take longer than that to code it's probably not worth it. I'd really like to be able to show some skill and do this, though (I've only been here a few months and this would be a good opportunity to provide some added value).

I need to export Chart(image) and grid (tabular) row data into excel file. I can not use automation because Office tools are not installed in my server. I've found a bunch of free/proprietary tools like:
NPOI
MyXLS
ExcelWriter (softartisans)
JetCell (DevTrio)
Aspose.Cells (Aspose)
But I do not know which one is better for my needs. I need to export not only grid row data but also Chart (image), thats why I am thinking about.

I have a PDF billing template that I need to put in the various information for customers and then send them the PDF's. I was looking into coding this with VB and saw iTextSharp mentioned a few times.
When I googled it I only found something on SourceForge and it was written in C#, where do you go for something in VB.net?

I'm automating downloads. I was getting this error quite a bit using Webbrowser to navigate to a PDF (various PDFs at various websites). In other words the PDF was already on display in the browser when I called WebClient.DownloadToFile. I got a LOT better results when I desisted from WebClient and switched to this API (just pass in the two strings along with zeroes for the other parameters).
[Code]...
And yet Webclient seems oriented for only two entries (username and password). How do you set up the credentials for three entries? I hate to abandon WebClient, but at this point I just don't know how to make it work.

I'm trying to use the Global.asax file in the root application of the website to catch requests for pdf files in the root that don't exist any more. I've configured iis to send pdf requests to asp.net. The whole thing works perfectly on development. It also works on the live system with missing .aspx pages, but not .pdf. Instead an "Error Code 64: Host not available". I'm using the Global.asax file to avoid the web.config and child applications (1.1 & 2.0) inheriting settings.[code]...

I'd like to be able to create, name and store individualized reports (school report cards, actually) with VB.Net and Crystal Reports using data from our SQL database.
It would be even better to be able to automatically generate individualized e-mails using e-mail addresses stored in the database, attaching the aforementioned PDF reports and sending them off.

I have been trying to make a problem, that allows me to open a excel worksheet into the datagridview, and then print the datagridview out. However, the code that I'm using now to import the excel worksheet into the datagridview, doesn't import the images from the excel worksheet.[code]Is it possible to get the correct posttion of each table, and the images, so if i print the datagridview out, it look just like the excel worksheet, but was just edited before printing.

Is there a way to print a form without streaming it into an image?
0. specify coordinates of each element and print
1. save the form as a pdf and then print the pdf
For 0, I wouldn't prefer that since it is too messy
For 1, it sounds like a good idea. however I dont want to save the pdf. Is there a way this can be done?
PS: I am using VS 2008 Express edition. I believe I cannot use powerpack.

I'm developing app in VB.NET 2008.
I have one prob that i'm creating excel sheet runtime, loading data and printing excel sheet through my application. Actually it has 150 sheets to print.
i'm printing by using this code
xla.Sheets.PrintOut(Copies:=1, Collate:=True)
To print 150 sheets , its taking around 17 min. so now the user is waiting until printing process finish(ie 17 min ) .
actually i don't want to make him wait, i want to execute this printing process in backgroud. so the user can work on other process in my app.
how to print this in background ?

I can't get this to work. My program fills all the values into an Excel spreadsheet- no problems there. What I'd like to do is a print preview/print function. I can't seem to get my code right, all I get are blank pages in the print preview box.
Dim oExcel As Object = CreateObject("Excel.Application")
oExcel.Workbooks.Open("C:DailyLogsDailyLog.xlsx")
PrintPreviewDialog1.Document = PrintDocument1
PrintPreviewDialog1.ShowDialog()
oExcel.Sheet1.PrintPreview()
So as I see it, this should open excel, then navigate to the actual excel file. The print preview dialog should come up, which it does, and the excel sheet1 should be previewing, but it's not? I don't have any errors, just a blank print preview. At least thats how I see it, but obviously I'm wrong because it won't work.
