I'm trying to find an easy way to export data from my database using VB. I already managed to write some textbox values into excel, but since this takes a lot of time and is not practical in my program, I need to learn how to export masses at a time...
So, I need to write 6 different values from the database table (shown in the picture in red) that are decided by 3 other values (shown in the picture in blue).
I have a Form1 where I can choose the "ProjHenkID", "Ty�Nro" and "Pvm:" (shown in blue)...
Started the code like:
Dim MyExcel As New Excel.Application
MyExcel.Workbooks.Open("C:Tuntilappu.xls")
MyExcel.Visible = True
but don't know how to call values from the database and insert them into specific cells in Excel...
having problems getting one of 2 pictures displayed when I run the program. In a whole, this is a coin tossing program that, after the toss button is pushed, is supposed to show either a coin heads or tails image while also displaying True or False for heads or tails respectively. Additionally, a running tally of how many times heads and tails is displayed.The main issue right now is that when I press the toss button, no image is displayed, but True or False is displayed as well as the running number. After checking, running numbers correspond with the T/F results. The secondary issue is that a running tally is displayed, but instead of it being in a single or double digit increasing format, it shows up as 0011122223345666 as you keep pushing the toss button. I've researched books and the web to find out where I'm going wrong and to get more clarification on why it's not showing, but I haven't been able to decisive.

Dim randomObject As New Random()

I am building an application using vb.net with sql server for a small company which requirs me to create reports that contain images. In my application I use microsoft report (rdlc) and I don't using any data source wizard, I just add empty datasets and bound them from sql data when the application loading. By doing this, I want to retrieve images from my sql field and display them in my reports. I've tried to drop an image control from the report items into my report, match its value with an image field in my dataset, select database source and choose a appropriate MIME format for it but it doesn't work.

View 3 RepliesI have created a basic word processor and come across a small speed bump; I have used a rich text box as the input, the user will be able to paste an image into it with no problems.
However I can't seem to find away of browsing for an image in a directory to insert into the rich text box.
i have an aspx web form with vb code behind. the form is a simple input form with a table with textboxes and a submit button. i am looking to be able to insert a captcha image into the table with an entry textbox and check the value entered against the image on the submit button.
i have found various 'helpful' bits of code on the net to explain how to generate the image. but none of them explain exactly how/when the image would get generated, how you can insert the image onto the webform where you want it to be, or how you can check the text input against that image.
Is it possible to insert an image to a directory from my resources when i start my application?
Im using this to create a directory when the app starts.
Dim dir_name As String = "C:Wallpaper Changer"
If System.IO.Directory.Exists(dir_name) Then

I want to add data to a column in excel but I need to do it without inserting a row. I want to type the data in the top cell, execute an event, have all of the data shift down, and then clear the cell that I typed the data in. I can't insert a row because I have calculations that are based on each individual cell in the list in adjoining columns. I can get this to work by inserting a row but can't get the loop quite right without doing it this way.

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.
The code that I will be posting here in this thread is about inserting image into MS Access database. I have a problem indicating an error saying "Parameter is not valid".

I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""

I am running into trouble converting the ActiveChart.Paste method. I can't get it to work in VB.NET. It either throws an error or It just leaves an empty box when I do it in VB.NET (if I add .chart before the paste it runs, but doesn't paste any values), but in VBA it fills in the values of interest. I have tried creating a chart object, but that did not seem to work either.

We're exporting a set of data using .net interop to Excel and our template file contains some images. Depending on the amount of columns we're exporting we want to position the image X pixels left of the last column depending on the image size/width. Using the record a macro function moving the Image around is a 'no op'. Setting the Shape.Left position also won't work.

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:

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.
