I have a small, in-home peer-to-peer network with 2 XP professional nodes and 1 XP home node. One of the XP pro nodes has 2 printers on it that are shared over the network by the other 2 systems. I have a Linksys wireless router that attaches by cable to the system with the printers and by...

I need to connect to an Access database from a C# program so I can issue SQL commands (queries and nonqueries) to it, and I don't have the faintest idea how the go about it. I'm working in Visual Studio 2003 and the database is already created. Can someone show me how, or point me in the right...

Can someone, anyone, maybe even someone from Microsoft, please tell how to make fixed width fonts work with a dot matix printer such as my Okidata ML391. I running Windows XP and printing from Visual Studio. When I select a fixed width font so that the printer will print faster using its own...

Can someone, anyone, maybe even someone from Microsoft, please tell how to make fixed width fonts work with a dot matix printer such as my Okidata ML391. When I select a fixed width font so that it will print faster using its own internal font instead of the bit mapped TrueType fonts, it prints...

I'm a Windows XP and VS.NET user. I have an Oki ML391turbo dot matrix printer on my system. When I print out listings from within VS, the printing is not spaced correctly, either horizontally or vertically. Windows overrides the front panel setup of the printer and, using True Type fonts, is...

I'm a Windows XP and VS.net newbie, so be gentle. I like my listings on fanfold paper for debugging, so I bought an Oki ML391 turbo dot matrix printer. I hooked it up and everything works great except that when I print out listings from within VS, it sends out printer formatting commands that...

I need to write some code in Visual Studio which interfaces directly with the serial, parallel, and keyboard ports of the PC. I have many years of experience doing this in assembley language in embedded systems, but when I try to understand what the Microsoft C++ programmers have provided to...

I'm running XP Pro and it must be corrupted in some way because when I try to install SP2, it dies a horrible death, and my system along with it. I have backups, but they are obviously of the corrupted system. I would like to save the settings, favorites, and emails from IE and Outlook and...

Something has invaded my IE and sets the home page to something like "Icanfindit.com" or something like that. I reset it to what I want but the next time I come it's been put back to this page. It's very irritating. Does anyone know what this is and how to get rid of it? I've also had...

In C#, how can I determine whether a file exists out on the disk or not? Thanks

Another newbie question: how do you convert an int to a string for printing, but format it in hex rather than decimal?

How do you convert an array of bytes to an int or a float?. I'm reading in binary bytes of data from a file. I have to take them 4 at a time, reverse their order (because they come in "wrong endian"), and then combine them into a single int or a single float. I know how to do...

Microsoft apparently stores dates as an integer number of days since Jan. 1, 1900. At least the application I'm interfacing with does. I need to find some C# or .net classes which will handle Microsoft format dates and figure what date is represented and create a string containing a...

I know this is a very basic question, but I can't find an understandable answer for it. I want to create an SQL insert command in Java to send to an MS Acess database. I want to send values that have been computed and so they don't exist as strings. I need to know the syntax I need to use with...

I am trying to read the MSysObjects table in MS Access in a JSP, but I get an error saying I don't have permission. How do I go about getting permission to read this table? I'm pretty new at this and I don't have a clue as to how to handle this problem. I am including the short test program...

I am querying an MS Access database from Java. I want to find out if a certain table already exists in the database, or whether the program has to create it. I would like to know if there is an SQL query that will tell the program if a certain table exists or not. Any help would be greatly...

The data that I am reading from a file written by another application on a different web site is wrong-endian for use in Java (I can never remember which endian is which). I can reverse the 4 bytes in an int successfully using the following code: public static int SwapIntBytes(int i) {...

Microsoft apparently stores dates as an integer number of days since Jan. 1, 1900. I need to find some Java classes which will handle Microsoft format dates and figure what date is represented and create a string containing a human-readable formated date. Classes that went the other way...
