Is bindingsource.count only used to give the total items in a list? I'm trying to prepare data for a pie chart, and need to count the instances of different items in a column (If there's a way that the Chart will do this itself, I've not been able to find it, it seems to need linked items and values). The bindingsource is already filtered and would prefer not to combine filters.Would it be best to loop through the rows of the column and count them 'manually' or is there a quicker way of doing this?Put it in a datagridview? Is it possible to use Aggregate Count on a bindingsource?
View 4 RepliesHow would I go about counting the number of times a given query occurs inside of a text file using LINQ?I need to search through the attached file and see how many justices were appointed by each president, and then create a new text file displaying the following:
presName, justiceCounter 'president name ordered by first name, number of justices appointed
I pretty much get how to do everything except for keeping an accurate counter within the LINQ query. However, I do feel confused about the order in which I should write this code, as in where I should keep my counter for how many justices a given president has appointed.
My output is displaying like this:
Abraham Lincoln,111
Abraham Lincoln,111
Abraham Lincoln,111

I am attempting to write a very basic console application which simply counts the number of times a word appears in a sentence. This sentence is input by the user, as is the word to look for.(I also need this search to ignore the full stop and case, but I'll try and do that myself)For example:
Sentence: "This is the last time that I'll say this."
Look for word: "this"
Expected output "2" (as "this" appears twice in the sentence)
I have written some basic code below, however, the output is a boolean value rather than a count of all the times the word has been used.I have a very limited knowledge of VB, so the solution is probably going to be long winded and simplisitic. I am a mature student at university, hence the reason I am writing these odd looking applications.

I would like to count the frequency of words (excluding some keywords) in a string and sort them DESC. So, how can i do it?
In the following string... This is stackoverflow. I repeat stackoverflow.Where the excluding keywords are
ExKeywords() ={"i","is"}
the output should be like
stackoverflow

txtSubject1Info.SelectionStart = txtSubject1Info.Find("Hey!")
I am finding specific words in the RichTextBox (in this case, "Hey!") and selecting them by getting their initial position through the "Find" command. Unfortunately, this does not work when I have multiple instances of "Hey!" in the RichTextBox. Here's an example:
Text in RichTextBox:
Hey! This is cool!
The Find command would return a value of 0 in this case. However, let's take a look at another scenario:
Text in RichTextBox:
In this case, the Find command would return a value of 0 again, but I want it to get the initial position of the second "Hey!" statement. I'm wondering how I can do this.
How would I find all instances of a letter if it appeared multiple times in a word? For example if I had the word 'mississippi', how would I find every 's' or every 'i' or every 'p'?
I know how to use the string.IndexOfMethod() so I was thinking I could find the first letter, mark that position, and search again from there. Then I would keep looping until the end of the letter. But I'm not sure how to signal the end of the loop.
Basically in visual basic 6 I could access word tables in existing templates with the code owordactivedoc.tables(1).select() where owordactivedoc refers to the active word document and tables(1) refers to the first table in the template.Trying the same code in VB 2003 just leads to errors. Secondly how do I access bookmarks or alternatively word variables.Furthermore how do one deploy web.services. For example the current program I am building is for another computer. Simply copying the web service to Inetpubwwwroot dont work because it is not picked up by the Internet Information Services program. I have to create the web service in vb2003 on the other computer change msconfig manually. Copy and paste the existing service vb file in the created folder replacing the empty vb file.
View 3 RepliesWe have an interactive windows based application written in VB .Net 2010. It uses Word Object to display documents in MS Word. We have a form with a button. When the button is clicked we open the Word document and maximize the Word Windowstate. When we have the Visual Studio Tool running, the Word Document is maximized and has focus, even if we are running the exe from the bin folder outside of the tool. However, if Visual Studio is not running and we run the exe, focus remains on the original form window and the document stays in the task bar.

I have been trying to figure out how to read paragraph content which exists a heading. The heading itself is part of the table of contents. The heading will have a particular style (say Heading 1). For example: "Introduction" is a entry in Table of content with style Heading 1. I want to read content under heading "Introduction" but not any more content (i.e not content under sub headings of Introduction) I have been trying to do this using styles/style, TableofContent, Paragraphs/Paragraph,Range.

I have a VB.net application that gets data off our server with ODBC and populates and saves a Word Document. When I try to deploy it to another computer it will get the data just fine and populate the first document, but it will crash before saving it. I've installed the .net framework 4.0, Microsoft Data Access Components, and the Microsoft ODBC .net data Provider. The error code is 0xC0000005, which is from what I can see is called an "Access Violation Exception." It works fine on my computer.

I have document, with numerous pages, that will populate at key locations using a UserForm and bookmarks. One of the pages in the document may need to be repeated. In other words, one of the pages may need to be populated more than once (and inserted successively in the document).
The troublesome page has bookmarks that will need to be repopulated with different information for every new instance within that same document.
I am considering making a table with the verbage in the "Troublesome Document" located in a Table. When I need to repopulate a new instance of that page, I think I should:
1. populate the document
2. copy and paste the wording in a new page
3. insert the new page (without bookmarks yet maintaining formatting) before the "Trouble Document"
4. repeat steps 1-3 for every necessary instance
5. delete the "Trouble Document" with the Table
I'm trying to read a word document for the purpose of obtaining a word count, I realise Word has built in functionality for presenting a word count but I want to write a little app that will omit certain parts of the document from the word count.
So far I have tried this code to open the document but I am getting an error 'Word.Document cannot be found' and 'Microsoft.Office.Interop cannot be found'. I have added a reference to the Microsoft Office 12.0 Object Library under the COM tab. I have Office 2007 installed and I'm using VB2005.

Dim appWord As New Microsoft.Office.Core.Application

I have developed a WinForm Application with VB.Net (VS2010) having Office 2010 Professional Installed, and it is 64-bit Windows 7 Platform. The program opens a .doc and .rtf format document, and attempts to save it in htm format. I am using following commands:
Dim sFilePath as String = "C:ABCfile.doc"
Dim oApp As New Microsoft.Office.Interop.Word.Application
Dim oDoc As New Microsoft.Office.Interop.Word.Document
[code]....
All goes fine with development and running on development PC, but when I publish it for offline installation, and deploy it on Client PC having Windows XP with Office 2007, it gives error on oDoc.SaveAs2 line, and program crashes.
The following code allows words to be added to a listbox. Add the word to a text file and create a folder with the word as its name. The second part undoes the actions.If I try to delete the word immediately after adding it one of two things happen.
1.An error is reported stating the path cannot be found. Although the listbox index value is correct according to the code the error is pointing at that index +1.
2.The code continues to the point of requesting conformation to delete the folder, still pointing at the index value +1. I the action is confirmed the wrong folder is deleted.
However if I stop debugging, then run the code again all works correctly.Is it likely to persist when the application is compiled?
