IDE :: How To Run Program After Changes Were Made Without Being Forced To Save It
May 27, 2009
In my Tools/Options box under Projects and Solutions/Build and Run, I have selected: Before building: to "Don't save any Changes."However, after making changes to a form, I would like to run it without saving, but I get a message that forces me to save, unless it runs the version of the program before the changes were made.The VB 2005 edition works the way I want it to allow testing without saving, but VB2008 does not allow this.Is there any way I can change this behavior?

I am able to read and write text files fine within vb using this project.
How can I detect if changes were made within the form textbox after opening a textfile? I want to prompt an OkCancel msgbox, if changes were made, upon menu exit or opening a new file.[code]...

I use a DataGridView to Add/Edit/Delete records from an Access database. Doing those 3 things is working just fine. When I try to update the database with the new Table data, nothing happens. I need to basically overwrite the table in the database with the data that was added, edited or deleted in the DataGridView. I opened the connection and got the table data like this

I'm making a video editor program and I'm getting kinda stumped at the save portion, I've worked with openfiledialog so I figured save would be sorta the same. What I'm doing is adding files(music,videos, and pics) to a flowlayoutpanel. I just don't know how to save those controls made at runtime, this code is my import code. It's pretty much the same for music, video and pics with the exception being the format and openfiledialog being used:

Is it possible to save into temp data a user made class? I have a class with many structures and each structure contains variables and im trying to add to my program a way to save the data of that class object with its structures and everything is that possible? I tried manually making some sort of save but its taking too long and proving way too hard for me. Is there a way to just convert it into some general object format and save the object? Is that possible can you just save undefined objects without having to create a format manually for that object?

I'm having a really hard time with this. I have a situation where I'm running an "internet kiosk" kind of situation. So i'm forcing firefox to run as a shell with some custom settings that prevent users from tampering with anything. Problem is, and this is well documented, you force windows to use something thats not explorer.exe as the shell - you get to wait 2 min before the welcome screen dies. I'm running XP Home - I've tried disabling the Welcome screen in the registry but, nothing seems to work. I keep running across snippets of code refering to something like this:[code]
I've used C++ a few times, so I sorta kinda get whats going on, but I have no idea how to implement it. A lot of people are talking about just adding these snippets to the beginning of their custom shell applications. My shell *is* an application, so i can't add any code. I need to know how to send this signal to the kernal so i can shorten my boot time. I'm assuming I need to take some VB code and turn it into an EXE so i can run it at boot - I tried SHELLing this out to cscript.exe in a batch file, but it says theres errors.

I have made a VB.NET program on my laptop. It works just fine on the laptop. But when I install it on another computer it wont open (when I click on program it wont open form). I think I had this problem once before, but cant remember what I did to make it work. Its Win XP on the machine that wont open program and Win Vista on the one that it works on.

right here ever experience having their programs made in vb.net run slow on the computer it was deployed at?
what are the system requirements to run a program made in vb.net with framework 3.5?
is it a simple program or a large program (eg with database)

I have a project im working on in which data is loaded from a database using sqlite into a datagridview, one column in this datagridview is a custom rating column which windowsmedia like rating stars are displayed and when moused over the image is changed using the following custom column. When the mouse is moved in a cell the cell is forced to repaint and display the star image according to the mouse location in the cell.Now the odd thing is that this works perfectly when the data is loaded in with the SQLreader and added row by row, but when the data is loaded in using fill() using a datatable the cell will not repaint when moused over unless its row is currently selected or has been selected. Everything works fine loading the data row by row but loading time is much longer when there are 1000 items in a table.[code]

I have a web service with both SOAP and REST endpoints. I have to accept requests from a client that I do not have any control over on my REST endpoint. Currently the client gets a 400 response and the tracelog on my server shows this error:
The incoming message has an unexpected message format 'Raw'.
The expected message formats for the operation are 'Xml', 'Json'.
I've tried everything I can think of with the WebContentTypeMapper but seem to end up right where I started every time. The request from the client doesn't appear to be well formed XML or JSON so if I try to force XML or JSON types from the WebContentTypeMapper I end up with parser errors.
So I guess I need to find out if I can force this endpoint to accept the message anyway.

I've seen used the datagridview to save the changes.
I don't use a dgv, but rather I connect directly to access and when a text field has text in it, it takes that text and searches, and updates various text boxes with the according information (finds a row, and takes all the data in the columns and adds it into their respective box). There are approximately 5-7 text boxes being used at the same time, and only a few will be changed.
How would I go about updating and saving through the VB program?
Here are some relevant pieces of code:
Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=C:\InventoryMusic.mdb")

I have numberic updown control in my app. There may be times when I want to programatically change the vlaue (in which case I don't want to ValueChanged event handler code to run). There will certainly be times when the user makes a change (in which case, I would want the event handler code to run).

I was wondering if anyone knows of any way of statically linking all dependant DLL's to the vb.net program? I know there are ways to find the dependencies using dependency walker and other tools like that. But was curious since c++ supports the static ability to load DLL's. If not, what tools can i use to quickly package the required DLL's without having to install .net on all my systems?

After debugging a particularly tricky issue in VB.NET involving the order in which instance variables are initialized, I discovered that there is a breaking discrepancy between the behavior that I expected from C# and the actual behavior in VB.NET.Nota bene: This question concerns a slight discrepancy in the behaviors of VB.NET and C#. If you're a language bigot that is unable to provide an answer other than "that's why you should use C#, noob", there is nothing for you to see here; kindly move along.Specifically, I expected the behavior outlined by the C# Language Specification (emphasis added):
When an instance constructor has no constructor initializer, or it has a constructor initializer of the form base(...), that constructor implicitly performs the initializations specified by the variable-initializers of the instance fields declared in its class. This corresponds to a sequence of assignments that are executed immediately upon entry to the constructor and before the implicit invocation of the direct base class constructor. The variable initializers are executed in the textual order in which they appear in the class declaration.
Contrast that with the portion of the VB.NET Language Specification concerning Instance Constructors, which says (emphasis added): When a constructor's first statement is of the form MyBase.New(...), the constructor implicitly performs the initializations specified by the variable initializers of the instance variables declared in the type. This corresponds to a sequence of assignments that are executed immediately after invoking the direct base type constructor. Such ordering ensures that all base instance variables are initialized by their variable initializers before any statements that have access to the instance are executed.
The discrepancy here is immediately obvious. C# initializes class-level variables before calling the base constructor. VB.NET does exactly the reverse, apparently preferring to call the base constructor before setting the values of instance fields.If you want to see some code, this related question provides a more concrete example of the divergent behavior. Unfortunately, it does not provide any hints as to how one might coerce VB.NET into following the model established by C#.
I'm less interested in why the designers of the two languages chose such divergent approaches than I am in possible workarounds for the problem. Ultimately, my question is as follows: Is there any way that I can write or structure my code in VB.NET to force instance variables to be initialized before the base type's constructor is called, as is the standard behavior in C#?
