Make Do Public Sub/functions While Accessing Excel?

View 9 RepliesAccessing Hidden Properties Of Excel 2007 VBa Objects
Jun 22, 2009I need to migrate from Excel 2003 VBA to Excel 2007 VBA. When Microsoft introduced Excel 2007 it removed many objects from the previous versions and added some new objects. Also it hid some properties of particular objects. These hidden properties can be viewed by going to the object browser, right clicking any object and selecting "Show Hidden Members". My problem is I need to access these hidden properties. Is there any way I can access these properties. I can successfully migrate from Excel 2003 VBa to Excel 2007 VBA with the same functionality?

Nov 17, 2011I have am using an XBee ZigBee wireless module to communicate with a project of mine. I currently have it set up to the point where I can open a hyperterminal session to COM 4 (which is the usb com port), and recieve the data that is being sent via the microcontroller on the other side of the wireless link.
I would like to make an app that takes the data and puts it in to a more user-readable format. (Via VB 2005) So far all I have come up with is some problems. It doesn't seem like I can use the built in serial port tool to access a "virtual" com port. From the following link:Quote:
Note You cannot use the Microsoft .NET Framework classes to directly access other types of ports, such as parallel ports or USB ports.[URL]..Do I have to use a "COM port redirector" to make it seem like a real COM port? Or is there some easy way that I am not thinking of?
Accessing Data Without Using Database (.Net 2005)
Jan 31, 2010Is it possible to add, edit, view and delete records using a file only (instead of a database) and .Net 2005 (VB.Net/C#)? The concept is that a file that'll work more-or-less like a database. One can add, edit, view, delete and query data to and from the file. The file, either cannot be opened directly or data inside the file should be in some encrypted form so that even if the file is opened no one can comprehend it. Data inside the file can only be manipulated by a front end application i.e. .Net 2005.

Oct 15, 2010I have 10 threads each using the same sub to do work. This sub is calling a function to save the results. How are the threads accessing the sub? Is each one getting a fresh copy of the sub to do its thing or are they using the same piece of code and need to wait for each other to finish processing? I don't get any hits when searching for such a specific scenario. I am wondering because it is about using sockets (usually lightweight stuff) to retrieve a resource and the cpu is working at 100% all the time. Still it is very fast, 900 internet queries finish in about 3 minutes.

Nov 10, 2008I have been doing some research into accessing devices on a USB port and it's kind of helped, but not really. From what I understand, I can use the IO.Port namespace to access a device on a USB port (usually). Let me know if this is incorrect.
First, I made a simple program that looped through the ports available. I get COM1 and COM3, but I have 4 USB ports. Where are the others?

View 9 Replies[2005] UnauthorizedAccessException Accessing Comm Port
May 3, 2006I'm debugging a VB app where I'm using a comm port attached to a bluetooth radio paired to another bluetooth radio in order to communicate with a remote barcode scanner. The pair of bluetoooth devices basically work as a serial cable replacement. Sometimes it works fine, but after a while I get an UnauthorizedAccessException message which breaks the program (see attached jpeg).
I only get this when I use the radios and not when I use a direct cable. I wonder if it has something to do with other bluetooth devices nearby trying to communicate with mine. I've used the .NET Framework 2.0 Confuration tool to adjust the zone security to give full trust to MyComputer, so I don't think it has to do with security, but I'm really going beyond my area of expertise here. I don't know what's going on.

I'm concerned because when I type the period after the ) it does not allow me to select value. I type it in and it does not give an immediate syntax error but I'm guessing that when I try to run this, it will fail the build. Is there an other reference I need to add or do you get the value of a field differently for Office 2010 than we did for Office 2007?

VS 2005 - Manipulating Excel From Console App
May 5, 2012I'm setting up a console application that ...
1. Executes a stored procedure that populates a SQL table for reporting purposes.
2. Opens an Excel Workbook.
3. Refreshes the Workbook.
4. Saves the Workbook.
5. Closes the Workbook.
6. Sends the Workbook as an attachment in an e-mail using the SmtpClient class.
Now, steps 1 through 6 are inside of a loop as I would like to use the same workbook for all my report refreshes. My perfect solution is to iterate this loop as many time as needed to have all my reports automatically sent via email as an attachment. The first time through the loop, it works perfectly, however, the 2nd time through the loop, I noticed when the application opens up the workbook, the workbook opens up as a read-only copy even though I properly closed the workbook prior to re-opening it.
I've tried to force the open as read/write but then, the 2nd time the workbook loads, an exception is thrown. I'm on Windows 7 and I noticed that the folder properties has a read-only check box which I make sure is cleared before running the application but then when I stop/pause the application to inspect the folder properties, the check box is checked again. I'm not sure if this is why I'm having issues when I open up the Workbook a 2nd time or not.
