I have been using access for my applications from over 4 years now. I realize its time to move on now and i need suggestions for a new database. Here are my requirements :should be able to connect it with Vb.net windows form frontend GUI - all database functions such as add/delete/edit/update will be done through the vb.net front-end only.Should be able to place the db on LAN and each client on the LAN can then access the centrally stored db through their individual front-ends.At the most 5-6 users will be reading/writing to the database at the same time , so the database should not crash or slow down Since i come from MS access background, i would like something thats similar to it so that i can learn and adapt to it quickly.Not very important, but i think its worth mentioning. This db will be the main central db for my .net application.My .net application will also be interacting with quickbooks and magento via some apis but ultimately all this data will go to the central db. So just curious, will there be any compataibility issues with the database that you suggest Should handle about 10 tables and around 10k records in each table Should be secure - just that i should be able to lock it up or anyhow prevent it being accessed from anywhere else other than the vb.net front-end.
Lastly, I would prefer it to be free to use if possible but not essential. I realize there are some topics like mysql vs sqllite and on databases, but pls understand i need suggestions for one that will be apt for the purposes i have listed above.
Edit : Just curious - Would i pushing the limits if i still stick to access - i understand access won't be good for multi-user access but i guess 5 users is not much ?
I'll explain what I'm working to eliminate the assumptions of a brute forcer. I'm working a Random SQL Data generator. What I need is a way to create a multi-dimensional array from multiple word lists, 1 dimension per word list. I have tried a few different things and nothing I've tried works. However, I have got it to work with a single word list and an array of 1. I figured there is a more efficient way of doing this than writing a massive block of select case and using multiple 1 dimensional arrays, this would end up very messy and inefficient it seems.No this is not for homework, this is for personal learning use only.I would post my code, but like I said, nothing I've tried comes close to working.
View 5 RepliesI have a small VB .Net application that, among other things, attempts to substitute system wide typed text by the user(hotstrings concept). To achieve that, I have deployed 'ahk2exe' and 'AutoHotkeySC.bin' with my application and did the following:When a user assignes a new 'hotstring':
Kill 'hotstring' exe script file if running Append new hotstring to the script file (if non exist then create a new one)Convert edited/new script file to exe (using ahk2exe)Run the newly converted script exe(somewhere there I also check if the hotstring has been already assigned)However, I am not totally satisfied with this method for the following two main reasons:
The extra resources deployed with the application. Lag: The time it takes for the system to kill the process and then restart it takes a minimum of 5 seconds on my fast computer and more on other computers. That amount of time is much more than the time it takes the user to assign the hotstring, minimize/close the window and then test his/her new hotstring. When the user does so initially with no success they will think the process failed. So this method is not very good for user experience.I am looking for a different method or implementation. May be using keyboard hooks? Or maybe adding a .dll library that achieves the same. Are there any resources you know about that might help (free or commercial)? What is the best way to achieve my desired goal?
I m trying to use multi code file that contains events, functions etc...I have a form that named Form1.vb, code file Tab1Codes.vb and a class ClassUsers.vb.Form1 is containing a function like:

Basically I want to create a little program with 5 or so text fields where I enter the specific names of movies. Upon pressing a "go" button it then does a google search(with certain criteria) for all textfield entries on the website [URL} and then download the files, if possible without opening a browser.
Search criteria:
-only video formats(.avi .mov etc)
-download url contains the "_de" tag (to insure german trailers)
That way it should hopefully find the right trailer and download it. If possible have it use progress bars.
How much work do you think this is? Or is it even possible? From a logical standpoint I don't think it's too much work... I am using Microsoft Visual Studio 2008 Express Edition. My project currently is just full of test code but I will post it anyway:

I have a question about creating a multi-language application and the use of resource files. I will explain what I have done and what I would like the final product to be like.I am doing this in VB.Net and using Visual Studio 2008 After creating a new project, I added a resource file to the project (Add -> New Item, Selected Resource File, named it Resource1.resx).
I then double clicked the resource file and was able to add some names and values. For example,
Name - lblFirstName, value - John
Name - lblLastName, value - Smith
On my form, I have 2 labels: FirstName, and LastName
In Code, I added
FirstName.Text = My.Resources.Resource1.lblFirstName
LastName.Text = My.Resources.Resource1.lblLastName
If I run this code, it works fine. John and Smith are displayed on the labels. Now for my question. Say instead of first and last name the labels (buttons, menu items, etc.) were actually words that would be different in different languages. What I would like is to have something like
EnglishText.resx
SpanishText.resx
GermanText.resx
Each resource file would contain the same names, just different values. Depending on what language was selected, decided by the user (from a menu), how can I get the matching resource file to be used.
Basically what I want would be FirstName.Text = My.Resources.<Language Specific Resource File>.lblFirstName
Is something like this possible? Is this an acceptable approach? Is there a better way of doing this? I try to check often to see if there are follow up questions or if more information needs to be provided.
well i am populating a listview with some entries from an explorer tree, but i want to create a multi-column listview in which column 1 holds
the name of files added by me and column 2 hold locations of the corresponding file.

abc_120811.txt
abc_130811.txt
abc_140811.txt

How can i store unlimited multi-row strings without the need of extra files?Example: the user enter a multi-row string into a textbox and clicks save. Then the program should save that somewhere. And then the user enters another string and clicks save. And then there is a combobox where it can choose between those 2 strings to load.Can i save them in some sort of collection like My.Settings.Collection? Where each text also has a header.
View 5 RepliesHow to exit from a multi-line text box without deleting the text inside when press enter
View 2 RepliesIm designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

What I want is character $ in Red color and other digits or character after $ in color blue.$ 480.00 I cannot use separate labels for digits and $ due to limitation?
I am trying to draw some multi colour text onto a form using the paint event and the GDI+ object (note it has to be done using the GDI as i will be needing to scale and do bmp pixel manipulation on the resulting graphic . I have so far managed to create a class and collection winch allow the user to move the text around and change the displayed string, font and colour.
My question is how can i change my class so that it draws multi colour text? and if possible allow the user (uinsg the mouse to graphically select parts of the text.

Example:

View 1 RepliesI'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?
I have a need to build an app that will access about 10 websites and pass data to them, etc.I've read about something called multi-threading when searching Google.

View 2 RepliesI have a line of data that represent a data import. When the import is done, I would like to keep that exsisiting line, and add another line for the next import.
