writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I have been writing VBA code for MS Access for years, but am starting my first project that will need to retrieve data from the Internet. I have come across code samples that use "Microsoft Internet Controls" and "Microsoft HTML Object Library", and I can make them available references in VBA, and available methods and fields etc. show when writing code, but I cannot find any documentation for these APIs. Does it come with MS Office on the CDs (if so, where?), or is it available over the Internet somewhere?

View 1 RepliesI'm writing a windows service (MacTimeFix.exe) to fix the Windows time on a Macintosh (it's like this: i live in Moscow (GMT+03:00), and Mac OS thinks that the system time is GMT+00:00 and adds 03:00 to it< and Windows thinks that system time is the local time).I need to execute my code when my VB app is closed. (it happens with the shutdown of Windows) The form is invisible (hidden), and the user mustn't click anything except windws shutdown button. It is a service. When i write a Form1_FormClosing sub, it works only on Alt+F4 or CloseButton and doesn't work when the app is stopped from Windows Task Manager or whatever also.I need a way to execute sub when app is closed with taskkill (without /force) or a way to execute a several app on Winshutdown.
Here is my code:
Public Class Form1
Dim SystemMary As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load

View 13 RepliesI have a searchbox that queries a database and shows the results in a box below. This is kinda slow when I use the ontextchanged event, cause the database gets queried each time a new letter is written.

I'd like to know if there's a better way to read/write various user settings to disk. My program loads up a bunch of settings during load but also during execution from a few different forms, encrypted string values, boolean values, different types. The code seems to work okay but I have a feeling it's just not the best way to be doing this. Some of the settings are encrypted strings that have to be decrypted/encrypted so the code to read/write the text file is a bit different on some items. The data read from disk usually goes to a public string, a textbox, or a up/down type control. Below is about 1/10th of the settings that get loaded/written at various times. Anyone have a better way that might be more efficient that I should look at?

View 2 RepliesDoes anyone have experience writing data to the parallel port (printer port) in Windows 7 64-bit. I have been trying inpout32.dll, inpoutx64.dll and following all the info on http://www.highrez.co.uk/ and www.logix4u.net but can't get anything to work. I have an on-board parallel port at &H378 - not an add-on card - and have tried various modes in the BIOS (standard, ECP etc). I have a background in electronics so I am confident my testing methods are sound; I just cannot get a data bit to change state under program control. I need to send data to an 8-bit port on some 20th Century electronics so serial/USB interfaces are not really an option. There must be a way to control those 8 data bits in Windows 7, mustn't there?
View 14 RepliesI am using WritePrivateProfileString for writing INI file in Windows directory and GetPrivateProfileString for reading INI file from Windows directory. In one of my system, I found that writing is not working but reading is working fine. On further investigation, I surprised to find another another Windows folder in C:document and Settings<username>windows. And WritePrivateProfileString is writing INI File in that folder, but reading from C:windows. Any Idea why it is happening? More information Windir Environment variable is returning C:windows and I am passing only file name not full path in the API function. This thing is working fine in all other systems.
View 17 RepliesI have a quick question. One of the functions in the program I am writing is to take all of the data entered, compile it into an HTML document, then place that document into a folder.For the past few days, I have just been using a random folder on one of my hard drives to dump the file in, but the problem is that, in my code, I have supplied the folder location as a string ("E:Practice FilesDocuments"), and therein lies the problem. Trying to test my program on a separate system brought the bug to my attention; obviously, this program can only write this file to a location of E:Practice FilesDocuments, and if any other computer that runs this program doesn't have E:Practice FilesDocuments then there is going to be a problem in the program working the way I have intended
So what I would like to do is instead of having it write the file to "E:Practice FilesDocuments," have it write to the default My Documents folder so that the program is no longer specific to my machine only. The problem is, though, I have no clue what the right code is to use. I first tried using
System.Reflection.Assembly.GetExecutingAssembly().Location to write the file to the default installation directory. This would have worked, but since this is a VB.NET program, the default installation directory isn't in Program Files and doesn't seem to be meant for users to browse through for their documents, plus it seems that trying to write back to this directory causes some unhanded exceptions and whatnot. I figured it would just be easier to create a folder in My Documents rather than use the install directory (and probably smarter).

What I am trying to do is I have a .dat file that I cannot read but can at the same time. What I mean is I know how to decipher it by hand (alas takes minutes per 6 parts and there are thousands.) I am trying to make an application that can read this and allow me to edit it from my computer. I can open this with a hex program such as hex editor neo. I am currently trying to get it so I can read the file and have it place corresponding parts in to text boxes that I can alter to suit my needs.
I am new to visual basic and know a tiny bit about C++ if you think I would be better off trying in C# I can try that as well I do know some since learning c++. There are 41 parts to each item listed in the file and each one would need to go in its own text box. In hex there are 348 blocks that need to be arranged in corresponding order. Also the beginning of the file has 6 block followed by a code for each item. I need to find a way to put all the correct code in the correct text box and have it make sense.

View 2 RepliesI'm writing a program which plays audio using a windows media player control. It's quite basic but I'm running into a problem.
Soundplayer.Ctlcontrols.play()
Sleep(3000)
For some reason when this appears in my code, the sound doesn't start playing until AFTER the sleep. I have music running in the background, using another windows media player control, that continues playing just fine.
Basically, I want nothing else to happen for the duration of the sound, hence the sleep, so how can I make it so my sound starts playing BEFORE the sleep?
