[2008] Accessing A Directory That Has A . In Its Name?
Jan 15, 2009
For some annoying reason you can actually create directories with full stops in them... and Microsoft just so happened to of set the default path for one of the Exchange server log files to go into a folder named Server.log. Yes it is definitley a folder not a file, there are .log files within the folder too though.
So, I'm trying to parse some of these tab delimited log files but I cant actually get at them because whenever I try and access the Server.log directory my code just dies. I mean, it doesnt throw an exception, it just stops executing. The form is still responsive etc but the parsing routing doesnt do anything and if i step into the code i see that it gets to the line that tries to access the server.log directory and then it just jumps straight out of debug mode.
If i move one of the log files out of the Server.log directory then my code works fine so what can I do?I tried using IO.Path.Combine but that doesnt work either (and for once I'm not saying "it doesnt work" and giving you no error details because im useless, its just because there are no error details!)

I have an external project (DLL) that I have referenced in my project. One of the requirements of using that DLL is to include an XML file in the same directory as the DLL. Now I know in a production environment I could just add that DLL to the GAC and place the XML file in that same folder. However, that doesn't help me when I'm trying to debug it. I have tried including it into the BIN directory but it never gets moved to the Temp directory when compiled.

I am building an intranet site and i want to display the users email(not the complete email), but the subject, from, date and time. However, the first step would be connecting to the exchange server using the NTLM credentials, which are the same, however, i dont want the user to have to type their password to connect to the email.

I Am a new developer in VS 2008. I am writing a small program that reads an XML file. Here is a snipet of code.
filename =
"XMLPolicyList.xml"
Dim DR As XmlTextReader = Nothing
[code]....
My understaning is that the system looks for the file in the bin/debug folder, so that is where I put it. But when executing this program. I always get a FileNotFoundException. The file name displayed is (filename). If I hard code the entire directory name and file name I get the same error and the file name is displayed with the same slash in front of it. For instance I put the file on the C drive and the error displayed C:(filename).I don't have the problem in older versions of Visual Studio. The same program runs fine in VS 2003. I'm thinking that there must be some sort of setting within VS 2008, but I have been unable to find it.

I want to create and populate populste several databases on my server MySQL. I pretty much know how to handle the data and queries once I have a connection, it is connecting that I don't know how to do. I have read all the help file I can find till I am sick of reading about "Northwind" which doesn't help me a t all. What I need are the three or four lines that establish a connection to MySQL at [URL] I need to be able to establish this connection transparent to the user who needs only to put thier user name and password for the site into a configuration file. Then I need to be able to create a database and give the user access with thier username and password. I know how to create the database but not how to set the username, password and permission.

I have been using GreaseMonkey for Firefox for about a year now and I find it wonderful, but I am really prefer using VB over JS and I would like to do some stuff that is on my computer along, not on the internet.I wrote some script for GM that read the contents of an iframe, and GM allows you to "include" which addresses the script runs on. This is really nice because it keeps the script from running where you don't want it to, AND it allows cross-domain support for communication between dom elements (in a round-about way).
I want to get away from using GM because I like some of the stuff I have already done in VB over the last 10 years and dont want to rewrite it all. So really I want to go back to my old stuff and learn how to get this functionality from VS2008.What I am specifically looking for is HOW in the world does GM listen for the creation on the window objects and run some script on it when it is finished?
Lets say I have a few webbrowser objects or other non-active xml, html or dom objects in my project. I want to retrieve info with one, send info with another, and display info with the actual webbrowser object.It sounds weird and I bet it could be used maliciously, but I mean no harm. Like I said, Ive been doing it for a year in GM already. I know .net really tries to prevent this kind of stuff cross-domain, but I figure if GM can do it, anybody can. The question is just how.
I understand how to access dom elements and all that, and I have some skill listening for events. I am just a little lost on how to combine the two in this situation. Grabbing an iframe is simple, and I realize I cant (shouldnt be able to) read it when I am acting in the parent object's domain. How do I sequester the iframe window away from its parent object once its loaded, or at the point before it loads its content so I can read it or more specifically add an event listener so I know when its finished loading? This seems super simple, my brain must just be addled.
I want to listen for the creation of the iframe from the project level, and I want to be informed of the document load from project level. I dont want to listen or do anything from the parent window object, so I really want the iframe sequestered as much as possible. Assume all iframes I will be dealing with are not of the same domain as the parent object.

I've just started learning Visual Basic 2008 and I am stuck with accessing a database through VB, I am using the Data Source Configuration Wizard. Everything goes fine until I start debugging, there is no information in any of the fields. However if I use a different computer in the house I can look at different records.

Basically I am creating a Windows Service as an 'updater' program to update all my software packages. Whats going to happen is every piece of my software that is installed in its program folder will have an Update.dll this DLL will be a library to do with the update of the software.
There will also be a database in the Updater program folder which will contain a list of all my installed software. So when the service starts it will open my 'database' which will load the paths to all my installed software to a string array. Each path in the string array will have a Update.dll in the folder.
What I need to do then is is in turn call a routine called StartUpdate() from each of those Update.dll which will then do all the work. So the service itself is fairly basic and doesn't really do much I just need to figure out how to access DLL's when I don't actually know what ones will be there while programming, Reason I am doing it this way is to support my future software programmes without having to update the updater.

I did some research (mainly in the Drawing namespace) about animated GIF files and I know you can see how many frames are in the specified GIF using the GetFrameCount method, however how I can access each frame directly/loop through them one by one. This is my first time trying anything like this and I can't seem to find the right methods, classes or information. I'm not even sure if this is possible using the .NET framework.

I was wondering if there is any way to manipulate layers of a psd from within a VB program. I would Ideally like to inserts just the psd file in and then once a command is clicked turn one of the layers on or off.
I know I can accomplish this inserting a jpg/gif for each layer and have that image be turned on or off by a button click, but I figured using the psd would save room and if something needs to be aligned differently I can just make a change in photoshop. Opposed to trying to realign the coordinates in VB

When I create the code to initialize the Sections array like this...
Dim MasterX as MasterStruct
Dim Temp as Integer
For Temp = 0 To 98
MasterX.Sections(Temp) = 0
Next
VS 2008 tells me that MasterX.Sections "is not an array or method, and cannot have an argument list."

I am trying to access objects created at run time.The following code works IF Options Strict is off. If it is on it indicates "Option Strict On disallows implicit conversions from 'System.Windows.Forms.Control' to 'System.Windows.Forms.TextBox'."
Option Strict Off
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim txt As TextBox = Me.Controls("T3")

I am having trouble formulating the type conversion.A Second problem I am having occurs when I create a groupbox at runtime and then add the textboxes to the groupbox. I am having trouble drilling down to gain access to the textboxes inside the groupbox.

I am trying to access controls that were added to the form and created code all before I added them to a panel. Upon form loading I create the form handle into a dictionary. then I call that dictionary ID and add data to the controls. I can't seem to add data to the controls inside the panel.. I think it is something simple. I may just be over looking the method I need to call.

For school and other reasons, i am making an application in which the user can draw tile based backgrounds, to then turn into long line of code , i think called CSV , which can then be used in programs such as flash, to draw a tile based background. I am currently making a flash game, and dont really like the other tile array making programs out there.
For instance, code such as [1,0,1],[0,1,0],[1,0,1] with the correct code would generate a 3x3 tile background with an X shape.Anyway, at the moment i am currently stuck.I have code up and running which generates a 2 dimensional background out of pictureboxes randomly, however thats as far as i got, i dont know how to access the pictureboxes created.
What i have right now is two variables, gridX and gridY, which determine the amount of tiles placed in a for loop. These variables would be used to determine the size of multidimensional arrays that store the tile data, and determine the map size.i intended each image to be clickable, so that its picture would change from black to white when clicked
When clicked, the tile would switch between two images, to represent two different tiles. at the same time, a value in an array created with the tile, would change from 1 to 0.Then when its time to make the code, i simply use a for loop to spit out the array in the way i want.
I understand that i could perhaps create a class for the pictureboxes, but i dont know how to, since ive never dealt with them, and i dont understand any of the guides and tuts.how to use a class so that i could add and change the properties of multiple dynamically created pictureboxes, but also change the value of an array created with the picturebox, when clicked?
i need all of this to be done however without adding or including any additional libraries or anything to visual basic as it will be graded on school computers.

When I try to access the controls of a form which is not yet created (i.e. to modify the contents of a text box , to press a button etc) , I fail , usually without even an error message . I found out that the only way to make my program go right is to take care that the form is first created before I try to access anything on that form . However this means I must use the Show method to create it and then to Hide it , which leads to an instant awful optical effect . I remember back in VB6 there wasn't such a problem ; it seems that in VB6 each time I accessed a control on a not-created form led to the form being created silently . Is there any way I could do that in .NET too in order to access my precious controls ?

I need to access a file path, but a part of the path is different on each PC. Mozilla creates a random profile name for each PC it is installed on. I can get most of the path through environment variables. I need to access the files inside of the default profile, but can't since I'm not sure how to access it.
Here's an example of the file path:
'C:Users\%USERPROFILE%AppDataRoamingMozillaFirefoxProfilesxxxxxxxx.default'
The only thing that stays the same with the profile name, is the '.default' part.
