'event Log Full' Error Prevents Opening New Express Database
Feb 27, 2009
Creating a new database in a Windows Forms project (done according to one of the MSDN tutorials) results immediately in a "The event log is full" error.The database exists as an item in the project, but cannot be opened or configured (i.e.,it doesn't exist really). newly installed MS SQL Server Compact Edition,This is a new computer (though fully updated), and to my knowledge no other versions of SQL server are installed.I note that someone else has contributed a message about the exact same problem (according to a preview in the MSDN search results page), although for unknown reasons clicking on the item does not take me to that message.

The program i'm running doesn't seem to open the database in stead I get this error:"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"ErrorCode=-2146232060Is there a way to fix this error.

I am having an issue with displaying a PDF in an iframe in asp.net. When the pdf shows up it is showing up without the Acrobat toolbar that allows the user to zoom and print. This is causing a major hassle for our customers because they cannot read the PDF in the size that it is. If you try and set Acrobat to not show the PDF in the browser and browse to that page you get a message saying that it is trying to open it in Full Screen mode.Below is the code I use to stream the PDF to the browser:
Public Shared Sub StreamPdfToBrowser(ByVal doc As Document)
Dim Ctx As HttpContext = HttpContext.Current
'// Clear any part of this page that might have already been buffered for output.

I've been in VB express for about tree weeks, formerly of VB 5 for about 10 years.
I need to open a form on top of the form of another application, that is, making the other applications form its parent. The title on the applications form can change, so searching for the form by name won't work.
I'm also curious, can you start a vb express application without opening its form? Like in Vb5/6 you could start in Sub_Main?

I have created a picturebox in a form that I want to click on and then it would send me to a excel file that I already have created. I don't know if it is even possible. Do I need to use a button instead?, or am I just way off all together.

When you Use Socket.Send Ether in VB6 with the Winsock control or Vb.Net sockets / Windows API does it generate that if you send "Hello" that on the other side it will get the Full Message Before the Data Arrival event is triggered??Or is it possible it can get it in two Different events like "He" & "llo" and a Last question, TCP is stream oriented, is there a Protocol that is Message Oriented but is wrapped with TCP, if not what is a good Delimitor to use with TCP, Usually ide use &H1 OR &H0 but I assume &H0 is common.. or Should I just add a Length Param before each Packet I send..?Now if thats the case and I got the Delimitor route... What if Im sending Chunks of 8192 of a File in a while loop and on a different thread I send a Command if I use the Length Param isent there a huge chance that the messages will get sent like this

BUT the issue lies as it thinking that only the 3 of 4 of the incomming file Frames are getting Recv due to it not knowing which frames are for which. Mainly due to me sending a big burst and on the other side recving random chunk sizes on the other side.Edit: Got another question, If I send two bytes across the internet via TCP, will they ever arrive as two different I belive the term is Frame or is that only when they exceide the size of the MTU will the Message be Split. The reason why is if I send a Header saying SOH, Length Of Message(2Bytes), thats 3 bytes can I say 100% of the time the computer on the otherend will recv that all at once so I can parse it? And What ever happen to Flush for Winsock?

Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

It's probably just a case of me not looking in the right place or not seeing the obvious, but does anyone know if a machine with just version 2.0 of the .NET Framework should be able to run a VB.NET Express application which accesses a SQL Server Express database file? Or is there an additional requirement for a non-development machine to have some kind of SQL Server Express runtime component in addition to the 2.0 Framework?It seems to be counterintuitive to expect that a VB.NET application would be able to access any kind of SQL Server data without having some kind of SQL Server host component (Express or otherwise) installed. But then again, it seems just as counterintuitive that Microsoft would require the download and installation of the new framework as well as a separate database runtime in order for the average user to run an application with accesses a local SQL Server Express database.To me, it runs contrary to the whole concept of XCopy deployment to require more than just the application's files and .NET Framework for an application to run properly. But nothing I've read so far explicitly indicates that a user would require anything more than the app files and the framework to run an application which accesses SQL Server Express data. But...I can't get any VB Express applications which uses a SQL Server Express databases to run on any machine that doesn't have SQL Server Express installed.What am I missing?(Apologies if this isn't the right group to post this in.

I have a process that I start in this manner: Process.Start("pwace", "/a C:18537-1ff.ace") The .ace loads a DBF and it is simply told where to find it like this: 18537-1.ace. When running the .ace file manually, this is fine. However, when starting the process through a VB program, the EXE (pwace.exe) acts like it doesn't know where the .ace file is located, so it can't simply append the .ace path to the .dbf to find it and the program errors out telling me to specify the .dbf with a full path.
So, I set an absolute path to the .dbf in the program, and it works fine. This leads me to believe it is an issue similar to shortcuts where if you don't set a 'Start In' path, your program has to have absolute paths defined to be able to launch external files with Process.Start(), and not simply filenames.
With that all said, is there a way I can indicate to the Process.Start() from VB where this file is located, sort of like a' Start In' path, so that my files don't have to be configured with absolute paths. And remember, it matters where the .ace file is located, not the actual .exe process that is started. The .ace file is simply a settings file for the pwace.exe to get it's parameters from. The reason I don't like to set absolute paths is because of the environment I'm in and for these .ace programs, it is better if the .dbf files are not given absolute paths.

Its based around space invaders and works quite well. however because i have finished my college project almost 2 weeks ahead of the assignments release date, my tutor has asked me to tweak my project and make it better.So far i have added a full main menu to the game and a full splash screen.

I hate to ask this question on this forum, but I'm having a lot of trouble finding it on these online tutorials. Basically, I'm learning about SQL, VB.NET, and how to glue the two together, and I've learned about using SqlCommand.executeScalar() to get the first entry in a table. But that's all it's really good for, right? Or is there something more to the story here?
Basically, I'm wanting to ask about how to pull in a FULL table from a SQL database while using VB.NET, as well as how to pry substrings and stuff from it. Again I'm having to ask this on this forum because all these online tutorials seem to ignore the subject completely.

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

I have a VB.NET form that takes up the whole screen. On Windows XP, the taskbar is not displayed when moving the mouse to the bottom of the screen. I have auto-hide set, and the taskbar is not locked. I tried the same thing on a Vista computer and it works fine. What am I missing on Windows XP? I need the auto-hide feature to work for my app like it does for other Windows apps.

I added an splash screen to my app. Then in the project settings I selected it to be used for the splash screen. Now my app won't close when I try to exit my app. I have 'When Last Form Closes' selected for the shutdown mode. So I'm guessing the splash screen is calling Hide() instead of Close(). I can't find a way to get access to the splash screen object so I can try callling Close().
