Feb 14, 2012I generated SQL Server 2008 Database scripts. There are total 80 objects. The script executes successfully from sql server query. But not from .NET. That is I want to create the objects (tables and stored procedures) from there.If the database don't exist already in sql server, it fails. I have included the line
IF NOT EXIST (DATABASE)...
CREATE DATABASE DBNAME
But it simply don't work and the process fails while the code perfectly works directly in SQL Server.
Any work around this? Can I run CREATE DATABASE somehow?

Forms :: Create A ControlArray Instead Of A Non-working For-Function?
Aug 7, 2011My Problem is, that I have some Buttons, Labels and TextBoxes I need to generate after the User told a number of Players. With the Code I'm using now only the last Player will have these Controls working, because they are moved - for example - from Player 1 to Player 3. how to create such a ControlArray The biggest Problem I have is, that these buttons have to have names like "1", "2", "3" and so on (or if it works somehow to read out the Index of a ControlArray the names will not be necessary).
This is the code I am using right now to generate the Controls, but as you see it won't work, because the properties will be changed when the For-Function restarts.What I need is a hint on how to get these Controls/Buttons into a Control-Array and then read out the Index-Number to use them in the Functions that are called.

View 4 RepliesCreate Log File To Track Progress And Populate Controls Via Text File Or XML File?
May 22, 2009I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

VS 2008 Getting .exe File Working?
Jun 21, 2010However I am trying to get my program into one little file. And I read how to Build Project and go to inRelease and get it from there. However it says this once I actually move it from its other files
Quote:
"*Program Name* has encountered a problem and needs to close. We are sorry for the inconvenience."
I get that as soon as I load it up. If there is any way at all to get it one simple file rather then like 3,4 files it would be so great.

View 4 Replies2 Methods Of Opening A File Not Working?
Oct 23, 2010I am trying to call a batch file from my program. It opens the file but the file doesn't work. This requires a little knowledge of java.
method one:
Code:
Dim odlg As New OpenFileDialog
odlg.InitialDirectory = path
odlg.Filter = ("Batch Files (*bat)|")
[code]....
Both of these make the batch file appear but somehow it isn't opened correctly or something. The two batch files are in the resources of my project. They get copied to a folder and that directory is named "path" which appears in the code above. Then I try to call the file from that folder with the directory being called "pathComp" which also appears in the code above. This batch file is meant to compile the java files created in a folder by the program by using the command "javac". Now when I run the program and get to this point and the batch window opens the cmd window says this:
Quote:
javac: invalid flag: *java
Usage: javac <options> <source files> use -help for a list of possible options
[code]....
It doesn't compile the files, however when I run the batch file independently of the program it works fine. I really need some help on this one. If you need it here is the code for the batch file that is called:
Code:
@echo off

Apr 19, 2009I just saw in some wordpress plugins, there are auto tag plugin, auto RSS fetch, just you install the plugin and it keep working for ever without calling it.What i want to do is to put a dll file inside my Images folder and it will monitor the uploaded files and edit them based on some options, i want this dll to work automatically just when uploaded in the right folder, and keep running forever This can be done? If no, there is another options to do so?

View 14 RepliesBatch File Not Working When Called From Shell
Apr 30, 2010We are attempting to run a batch file that will result in a submission to a help desk ticket system. When we run the batch file from command line on our W2003 platform, it works successfully. When we run the same file, called from our vb program, using shell or process info, it does not. With shell, we can see the batch file being called, but it is not resulting in update to the help desk ticket system. The vendor of the system believes it is a security issue. We are signed on as Administrator while running this. We set security permissions of cmd.exe to include Batch, per KB867466. What else should we be doing or looking at?

Error Log File Location Not Working On Vista With UAC?
Oct 13, 2009I have a program that writes unhandled exception detail to a log file stored in the same directory as the program itself. I am wondering how I can have keep the file in the same location, and not have to worry about a file write access. With Vistas User Access Control enabled, the file is not accessible unless the program is run as an administrator, which I don't need it to be for anything else. The file does not exist all of the time, it only exists after an error occurs. Users are encouraged to email the file to me and then delete the file. Thus the file should only exist if their is a error that the user has not emailed. I really want to keep it in the same directory as the program itself, or within a subdirectory of the programs directory, since the portable version is exactly the same program executable and I would like to keep it that way. I am not sure how to go about setting the file security, set it when I create the file if the file doesn't exist, prompting for Administrator privileges to create it with the security. I was also thinking that I could just set the entire folder containing the program executable when it is installed, and then it would be able to create the file without having to have administrator privileges.
