How to get the value on a specific row by searching?i.e., I have a gridview:

I need to accum some data based on whether or not an SSN number appears in the data. I have it in a string, what I need to do is search for a numeric pattern within the string such as:I looked into regex a bit, but I don't have much time to read deep into it (my company needs the program this week) and it seems too complex to grasp in such a short time. What I've came across so far is:
If (rec.address1 Like "###-##-####")
but I don't know if this will filter it out of the string (it can appear with an address attached to it).
I have a program which grabs the source code of a webpage and puts it into a string. I would now like to search the string for two values.
"video_id": "value 1 here"
"t": "value 2 here"
The problem, is that I don't know the position of the values, and I the values change depending on each webpage. All I know, is the text before the value, e.g. "video_id" and "t:"
Here is my code:
Dim videoid As String = TextBox1.Text.Trim
Dim wc As New System.Net.WebClient()
Dim result As String = wc.DownloadString(videoid)

View 2 RepliesThere's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;
bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...
Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.
I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

FirstName
LastName
PhoneNumber
Basically what I am trying to do is create a Search function where the user will enter a First and Last Name in the search boxes and upon hitting the ''Search'' button the program will look through the database and check if the records exists.
If the record does exist then I want the Phone number to appear in a separate textbox which is named txtPhoneN. I have included the code I use to connect to the Database. I have already managed code the part to Add new record to the database.

I have a excel report with one sheet called "Export Report". I then add 4 more sheets and rename them accordingly.
I then need to search in "Export Report" in column A, but unknown row for the word 'Definitions' and then once found I have to copy 'Definitions' and 10 rows belows it, to the sheet called "Definitions"
How can I achieve this? At the moment I am stuck at the point of finding the word 'Definitions'. I get error Exception from HRESULT: 0x800A9C64 at this line:
LastRow = xlApp.Workbooks(1).Worksheets("Export Report").Cells(xlApp.Workbooks(1).Worksheets("Export Report").rows.count, "A").end(Excel.XlDirection.xlUp).row + 1

I have a .NET dll which I use from a C++ program. Now I have to register the dll programmatically on a deployment computer. How do i do that (programmatically! not using regasm)? I remember, when I once called a VB6 dll from a C++ dll, I had to use DllRegisterServer and DllUnregisterServer. Is that still so with a .NET dll? It seems I have to somehow add the dllregisterserver function to the .NET dll.
View 3 RepliesI have a customer that needs to convert XLS files to XLSB. Has anyone done this programatically, (with or without an add-on --- doesn't matter --- just need to be able to automate it)? I'm looking for a way to automate this.
As a side note, the customer is asking about this because they use Sharepoint, and it seems it has a way to analyze XLSB files quicker and easier than XLS??? I'm working to improve my Sharepoint knowledge, but in the meantime, I'm trying to find an answer to this XLSB issue.

View 5 RepliesI've written an interface with a 3rd party web service in VB.NET. The final step in that interface involves the 3rd party delivering to us (as a stream) a PDF document. After streaming is complete I save a copy of the PDF on our servers, so that our users can view the PDF by clicking on a link in our system. The PDF opens fine in Acrobat X, but when I try to open it programatically I an error saying that "the file is damaged and could not be repaired". I can also open the file in IE just fine, with no issues, and the same code that displays this PDF works just fine on lots of other existing PDFs that predate the 3rd party interface.
I have emptied out temporary internet files as suggested in some posts I saw online. I also opened the PDF in Notepad++ and the %PDF tag is first, and the %%EOF tag is last, so there's certainly no corruption visible in the document source that I can see. Below is the (very standard) code we use to open PDFs into a separate browser instance on our site:
PDFFile = System.AppDomain.CurrentDomain.BaseDirectory & Request.QueryString("LetterPath") & Request.QueryString("Letter")
Response.Clear()
Response.ClearHeaders()
Response.BufferOutput = True

View 1 Repliesim trying to find a better way to end the application im working on right now programatically, sometimes a user simple wants to end it all and since in the properties of my project the program is set to only end after all forms have been closed, (oddly enough i close all forms and it still is executing so i use dispose method and then end) what would be the best way to end the application and free pc memory for everything attached to it? i use:
form1.dispose()
form2.dispose()
form3.dispose()
me.dispose()
End
as ive readed online, end simply stops the app and nothing else, which makes me think, does its data still persists in the ram? i want to clear everything and not leave useless resources anywhere.
