My application needs to extract an embedded file (OLE object) from an excel 2003 document to a file on disk. This file can be any type, not only an Office document. Searching in the web it seems to be possible by copying OLE object to Clipboard and later copying (binary) it to a file (¿perhaps using MemoryStream and FileStream?), but I see no working code about this.
View 1 RepliesThis is the code i wrote in order to First open a csv file as excel, then find the required three columns, n then read data from them n save the data into another variables showing them in textbox. As about the csv file, it contains many columns out of which my focus is on only 3 columns under title ID, L, Lg.Problem is Excel doesnt actually open but Excel.exe process runs in task manager. But by this point its not the compile error; Compile error comes at 'Next' Statement. It says Compile Error: Next without For!!

View 2 RepliesI have a csv file with 48 columns of data. I need to open this file, place it into a data structure and then search that data and present it in a DataRepeater. So far I have successfully used CSVReader to extract the data and bind it to myDataRepeater. However I am now struggling to place the data in a table so that I can filter the results. I do not want to use SQL or any other database.
So far, this is working in returning all records:

View 1 RepliesI am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
i think the answer is to loop each of the cells/columns/rows in excel then show it in the listbox... i think.. the problem is i don't know how...
is populating from a text file the same with populating from an excel file?

View 2 RepliesHere is what I did.
1. Went to data source window and clicked "add new data connection"
2. Choose Data Base clicked next
3. Clicked Create Typed UserInformation as the name
4. Next.... Under Data set name I typed UserInformation again
Does naming the database and the data set the same cause problems?
5. Created New Table called users for UserInformation Database.
6. I added the following Columns: FirstName, LastName, Address, and Phone
7. Edited the table to add a couple of people. Tom/Franks/108 blah street/5555555 and Bill/West/109 blah street/5555555.
8. I also reconfigured the data connection in the data source window to show the users table.
I have four labels on my form, a text box, and a button.
I want to be able to search the database by last name for what the user typed into the textbox when they click the button.
I know this is probably easy for all of you but I am still trying to get used to using databases.
I need to convert a VB6 application into VB.Net Windows application. The program pulls data from MS Exchange (UserID, firstname, lastname, etc - not the emails themselves) and places it in a .txt file. The code has been converted, but the program does not work. When the application is run, the .txt file is created, but is blank and I get a pop-up that shows the following, "trying to access email in outlook do you want to allow this?". The popup box is gone in an instant and when I try to click on yes, it does nothing. I always have to end the program as it is non-responsive.
View 14 RepliesIm trying to extract predominately table data from a PDF file, however, I would also like the option to extract image files (such as graphs, etc) as well.Is it possible to extract data from PDF files using a VB.Net application? Im trying to get this process as automated as possible, so Im trying not to use 3rd party applications such as pdf file convertors or in-line pdf readers.
Are there any free, or relatively cheap PDF data capture API's/code snipets that I can use to import data from a PDF file? Another option is to export PDF data/images into an excel spreadsheet. Is there a .Net tool that will allow this?
All I've been able to do is create the form. We have to get information off of a website and load certain information back into the textboxes on our form.
Assignment 6 - Text Parsing Many applications require you to extract information from a block of text. We will be using this heavily in the project. This project is designed to give you some practice extracting information out of text files. You will need to open up a file, search the file for some specific content, and then copy that content and place it on screen.
Go to Jobs.com and select a state that starts with the same letter as your last name (if there is no state that starts with the same letter, use the second letter, then the third letter, etc.). For example if my name was 'John Byway', since there was no B or Y, I would pick a state starting with W - either Washington, West Virginia, Wisconsin, or Wyoming.
The idea is you want to extract all the jobs information out of the page. We want to put the jobs names in a combo box, so the use can pick any of the jobs. Ideally, this would also show the information about each job. You don't need to do that. However, you do need to extract the information and put it on the screen (When you load the next job, the old job information will be lost, and you will be left with the information about the last job loaded)
Tasks
1. Go to the above address, view the source in the browser, copy and paste it into a text file. You do not need to access the Source of the web page within your application.(in IE go to View / Source; In FireFox go to View / Page Source)
3. Extract each job title and place the name in the Combo box.
4. Find and extract the following fields. Note, some jobs may not list all of these. In that case, get as many as are presented.
a. Date
b. Title of job
c. Company
d. Location
[code].....
Indicate on screen how many jobs you found. Note, you only need to look on the first page of jobs?
