That means that the code does the same as: boolVisible = False --- b { font-weight: normal; } Cannot find keycodev2.dll or invalid keycode khwo5-Jul-06 22:32 khwo 5-Jul-06 22:32  Hi, I'm working on VB.Net (Window Base), I have add crystal report in my application. When I make a setup file in my own PC and I have try to run the exe file, it seem work nice on my own PC. Then I try to run the setup in other machine, and try to run the exe as well, when I open the report from it, it give me a error msg. The error msg are look like this 'Cannot find keycodev2.dll or invalid keycode.' Can anyone teach me step by step to slove this error? Thanks. Re: Cannot find keycodev2.dll or invalid keycode Dave Sexton6-Jul-06 4:26 Dave Sexton 6-Jul-06 4:26  it's actually quite simple. assuming you've added a setup project to your solution, what you gotta do is 1. right click on the setup project in solution explorer and go to " Add > Merge Module..." 2. add the Crystal_regwiz2003.msm to your project. 3. to get your license key, click on "Help > About Microsoft Development Environment", click on the list box item for crystal reports and then click on the "copy info" button. 5. now right click on Crystal_regwiz2003.msm in solution explorer and select "Properties". 6. expand the (MergeModuleProperties) node in the properties window. you should see a "License Key" property. Paste the license key that you obtained from step 3 (remember to delete the other junk that was copied with it). to explain a bit... (from MSDN) Crystal_regwiz2003.msm configures registration information on deployed computers (server or client) in order to track licensing information. When Crystal_regwiz2003.msm is added to a setup project, it exposes a LicenseKey property that must be set before building the setup project. The license key is emailed to you when the product is registered. This key is also available from the About Microsoft Visual Studio .NET dialog box from the Help menu. Enter this license key into the LicenseKey property for the Crystal_regwiz2003.msm merge module. Note: If the license key is not set for the Crystal_regwiz2003.msm merge module, an error will occur when building the project. If the setup is installed on a target computer without specifying the license key for the merge module, various keycodedev2.dll errors will occur. --- sorry for the long explanation. Re: Cannot find keycodev2.dll or invalid keycode khwo6-Jul-06 17:15 khwo 6-Jul-06 17:15  In the step 6, it is I only need to paste the 19 digit inside the license key? After paste the license key, I have try to build the setup by right click the setup file at the solution explorer and choose build. After success everyting, I have copy the setup file and try to install at other machine, but the error still come out? What mistake I have make? Can give some advice? Re: Cannot find keycodev2.dll or invalid keycode Dave Sexton6-Jul-06 19:51 Dave Sexton 6-Jul-06 19:51  have you also included the correct merge module for your database type? Re: Cannot find keycodev2.dll or invalid keycode khwo6-Jul-06 20:42 khwo 6-Jul-06 20:42  What you mean by merge module for my database? I not understand this? Can you explain a bit? Thanks.

Shedding Light on Stored Procedures TheFoZ5-Jul-06 20:52 TheFoZ 5-Jul-06 20:52  Hello. I've read my text book and it tells me how to use stored procedures but it doesn't tell me what they are, how to create them and how to use the values returned. I've looked through the MSDN and maybe I'm typing in the wrong things cause I cant find the information I want. Can anyone help? What I am after is:- 1. How can I create stored procedures in Access 2003? 2. What do I do with them in VB.NET 2003 A table I have in a data base is called Houses. It contains a house address, phone number etc. How could I use a stored procedure to find a certain address or to find the next auto-number for my primary key field. Many Thanks The FOZ Re: Shedding Light on Stored Procedures DIMPLE_R5-Jul-06 21:05 DIMPLE_R 5-Jul-06 21:05  Try these links http://www.devcity.net/Articles/34/msaccess_sp2.aspx http://www.devcity.net/Articles/18/msaccess_sp.aspx --Dimple
