View 9 RepliesOne of the applications I've written uses DirectX in order to record the user speaking (basically for making verbal notes about something). It fails to work correctly when the installed version of DirectX isn't recent enough. I'm just using a setup project of the type inbuilt into VS 2005, is there a way to check at install time that DirectX is recent enough?
View 3 RepliesI have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

View 3 RepliesI'm looking for Version Control software that works with VS 2008 & allows multiple check-outs of a file, merging the changes as each version is checked back in. Obviously this would require manual resolution when two programmers changed the same procedure,but that rarely happens here-what usually happens is we have two (or more) programmers working on different parts of the program that happen to occur in the same file so only one of them can actually do their work at a time. Highly inefficient.
We're currently using Visual Source Safe, by the way. I 'inherited' this so I'm not *absolutely* certain it can't be configured for this, but if so none of the older programmers (in terms of time in this office) know about it. I think they used a home-grown program. Besides, I haven't been able to remember who I heard about it from so remembering that really isn't a help-at least not yet.

I want to add a counter for my program that basically counts the times I answered correctly and incorrectly.

View 1 RepliesThis is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form.

Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form.
