How .net Determines The Placement Of Files And So Forth
Sep 12, 2008
Suddenly whenever I build my applications, although I get a "build succeeded" result - the executables are either not updated or updated in the "wrong" place.So for example if after succesfully building I press <F8> to step through the code I get a message saying the "source is different from when the module was built"I have no idea how to begin tracking this down - how .net determines the placement of files and so forth.

I need to create a program that connects to a database and determines if what the user entered is in the database. Trying to do this in somewhat the same way that a translator might workchecking to find the word, and if found replace it with what is in the row beside it in the database)
Anyone have any idea on how i should go about doing this?
I know its gonna involve looping but as to how i am completely lost

I'm having some issues with the suppression of the typical javascript and other scripting errors that show in the webbrowser.I have three webbrowsers. The third webbrowser goes out and determines some action based upon location. The one thing I'm having trouble with is this example. It states that it should work but the errors keep on coming.I attached some of the code below. Am I doing something wrong?

I was trying to make a program for a teacher that automatically determines random students that he or she can call on.I'm trying to make a program that will allow the user to add student names to a listbox. Then, when a button is pressed the program will output a random name from the list. I keep getting a lot of errors and can't seem to figure out why. Finally, I need an exit button that should close the program. I need to assign access keys, have a proper tab order, and assign default and cancel buttons for the form. Also, if you know how to implement any extra 'bells and whistles' into the program,I've tried making this program but it comes up with either a lot of errors, or it just doesn't want to debug. Was wondering if I could either get some help with the coding or the "how-to" on doing this.

I have a program written in vb.net 2003 which has text boxes for integer input. When the boxes appear, they are filled with the default value of zero. When the program is run on a computer running Windows XP the cursor appears in front (to the left) of the zero, but when run on Windows 7, the cursor appears behind (to the right) the zero.
In xp, if the user enters 1 (one) a 10 is diplayed and the user must delete the zero. In Windows 7, if the user enters 1, there is a leading zero which disappears once they have exited the text box. Is there a way to force one presentation or the other?

I'm new with VB and a time program I'm trying to complete is incorporating a tick event. I have the code I need to use, and have the timer placed within the VB Designer but when I start the debugging process, 12:00:00 pops up in the text box. I would like to have it start incrementing after I set the hour, minute and second and initiate the Set Time click event. The code I have for the timer is

Im working on a program that is about to drive me nuts figuring out how to round and show only 3 or 4 numbers past the decimal placement and also show the scientific notation.
Here is an example of the code.[code...]
The problem here is that most of these calulations turn up so long that my text boxes just show a small portion of the answer. I have really investigated rounding and decimal placement but nothing seems to work...does anyone have a solution?

I'm working on my final assignment for my Visual Basic class, and the last assignment is to create a program which stores CD collection information. It works fine, but the task is to create a structure for the input information and use it in the Add buttons click event code.I'm not asking to have my homework done for me, but i'd like some advice on where I should declare the structure and how. Everywhere I try and declare it, it ends up closing that particular sub procedure or section. I've tried looking up plenty of help sites to learn about structures, but sadly they and the book are both very vague. The instructor also mentioned padding each entry, but that I'm pretty sure I know how to do

I want that new text to appear at the beginning of the existing text, not at the end of the existing text.I've got the following code but it's not working. The new text keeps going to the end of the existing text.
Dim newtext As String
newtext = TextBox1.Text
RichTextBox1.AppendText(newtext)

I am trying to put an unbound button in the last column in a DataGridView control and it appears way, way off to the right when I run the app. I have to scroll all the way to the right to get to the buttons and then manually resize them to show up the way I want them to. I am using the Edit Columns feature found in the Smart Tag of the control. It works ok when I place them anywhere else in the columns! It only messes up when I try to place them at the end of the columns.

i frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?

I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.

I am trying to import a bunch of excel 2003 files all with A:H columns and they are under the same headings etc. into a table in access 2003 database. This is a module in access im making. Im using a file search to look for every file that begins with Format (which they all do ) to get at all the files in the folder path. is there a more efficient way to do this? somehow select all files in a folder? and import each to the same table in access? The DoCmd.TransferSpreadsheet seeems to take each file path individually so I'm not sure how to get each file name in the folder to import it.
I have this at the moment:
Sub Import()
Dim db As Database
Set db = CurrentDb

I have VB project and I tried to use PUBLISH feature.It seems to create nicely some kind of setup program, but the setup program does not ask where to copy files (it does not seem to copy filesto target machine "PROGRAM FILES".)Is this setup program somehow different from usual installers?
NOTE: I want that app files are installed to Hard disk( from USB stick source)Is the signing recommended or necessary? My App is pretty simple, its just using access DB + printer api, should I still sign?

i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".
Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.
But when i write code like
Dim strTest As String
strTest = File.ReadAllText("ae.txt")
Debug.Print(InStr(strTest, "ä"))
i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]

I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase
If f.Exists is False, mark it as deleted in the database
Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

I am trying to retrieve file details from files in the Program Files folder. I receive an error while trying to retrieve file details.
Dim sFileName As String = ("%ProgramFiles%Windows DefenderMSASCui.exe")
Dim Info As FileVersionInfo
Info = FileVersionInfo.GetVersionInfo(sFileName)
Msgbox(Info.ProductName.ToString())
I receive file not found error at 3rd line. But if I change the path from "%ProgramFiles%Windows DefenderMSASCui.exe" to "c:Program FilesWindows DefenderMSASCui.exe" it works fine.
What should I do if I want to retrieve file details from the path which includes a "%" character?
