Trying To Suppress Error Screens
Apr 13, 2011
I am writing a program that tests our hardware write blocker units.When i send it the command to delete a text file on the device it should ONLY respond with my error message coded with a try...except statement.However the error message seems to be coming from windows 7 when it says "The disk cannot be written to becuase it is write protected. Please remove the write protection from the volume POCKET in drive F:" then it has the buttons Cancel, Try Again and Continue. If i click on Cancel or Continue then my error message comes up.Is there anyway I can suppress the "The disk cannot be written to." error message in Visual Basic 2010?

I've run into a couple of errors within my program which reads a text file. When a user clicks a button to read the textfile and an exception is thrown, i have it displayed as a string in a message box, but an additional message box related to runtime error 52 'bad filename or number' has shown up and continues to pop up, even after clicking ok. I am currently working on the error itself in the textfile, but until I can work around all of the variables with reading this file, I was wondering if there is anything I can do to either prevent the runtime error box from popping up or figure out why it's popping up so many times. The really weird thing is sometimes after clicking ok on the initial message box displaying the error string, it won't pop up and other times it does, repeatedly.

I am aware of the Screen class, but when trying to use Screen.AllScreens[0], I get something like .Device1. Instead, I'd like to have my screen's name, something like HP 24' something.

I have read the MSDN Page on how to suppress messages. I am unable to supress warnings for VS2008. [code] The problem was I had a series of parallel tasks that were dependent on check boxes. I wanted each task to to run simultaneously and then join back. I overcame the warning by using a callback method that decremented until all the call backs completed. [code] The warning was an Uninitialized Variable. Which was not the case as it was dependent on identical if-statements. I opted to use a callback method instead, which turned out to be a better alternative and did not lock up the GUI.

I often use VBA to automate internet explorer and interact with web sites.I can find links on regular URLs I navigate to, fill in forms on them, etc.But I don't know what these types of windows are that come up or how to get a hold of them to click links on them or enter text in their forms if there is any. It comes up then grays out the screen it came from. It looks like its some java popup or something. I'm not interested in the site this is from, its just an example of one to show what I mean. I've been searching and looking but can't figure it out.

I have 2 screens, and 2 forms. I want each form to fill a screen, so I did the following code:
s = Screen.AllScreens
f1.Bounds = s(0).Bounds
f2.Bounds = s(1).Bounds
(s(0) is my primary screen, and s(1) is above it.) F1 fills s(0), but f2 does not fill s(1). The size of f2 is set correctly but the location is set to (50, 0) instead of (0, -1024). Maybe location won't accept negative numbers? If so, how can I get my form to the other screen?

I'm compiling a VB.Net 2.0 app (created in VS2008) using msbuild, and now I've added a generic return type, it's giving me the following:
Warning: Type library exporter
encountered a generic type instance in
a signature. Generic code may not be
exported to COM.
Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.

for a test project that i'm doing i am looking for ways to program a LED screen. I ordered a few LED screens (320x160) that can be connected together). Using a special controlcard the whole thing can then display text etc. Using the software that a Chinese supplier gave me. All the above works fine. But I am depending on the software I have. I have VB.Net experience and I would like to put the software aside and write my own software. I would like to set up the COM connection and tell what LED to activate.
Problem i'm facing is that the chinese cannot provide me good use of the software dll files. I need a small Vb.net program that does the above. Would somebody be able to figure out how to do this.

when i call GC.ReRegisterForFinalize(obj) and changed my mind, i could call GC.SuppressFinalize(obj) and remove it from the list of object that requests finalization. problem is that when i call GC.ReRegisterForFinalize(obj) twice, it registers the object twice in the finalization-listing. i need to remove the object from the finalization-listing but multiple calls of GC.SuppressFinalize(obj) could not remove obj from the list.also, why is it acceptable for this function to be called SuppresFinalize when after calling it Finalize still occurs?

I have a PC with four LCD monitors attached, but often I leave it unattended and need only one monitor running. I've set up power strips so that I can flip one switch on a power strip to turn on or off the other three monitors. The problem is, when I turn off the other three monitors, the computer makes the disconnect sound every few seconds. you can go into Control Panel->Display->Change display settings, and under 'Multiple displays' disconnect the monitors you are not using, and them reconnect them when you need them again. However, this is time consuming to do manually.can I program this in VB .Net, i.e. is there a Class or some registry keys that I can use to connect or disconnect monitors the same way as through the Control Panel?

I'm building an application that essentially attempts to fill up all of the user's screens with a maximized form. On most machines this works. I'm simply using My.Computer.Screen.AllScreens enumeration to get a reference to all the user's screens (assuming a multi-screen setup). I'm then using the following to set the forms:

The data source is an Access 2003 table. I create the table in code and then populate it with 70 rows (each one empty apart from a date field). This unfortunately adds a 71st row (the placeholder for a new table row). Is there a way to stop this row appearing (I don't allow users to add rows anyway, only to edit existing ones, so this final empty row is just untidy and always empty).
Here is the code I use to create the 70 rows:
Conn.Open()
da.Fill(ds)
dsNewRow = ds.Tables(0).NewRow()

In the very near future I'll have to develop an application that uses multiple screens.
So I'll give you a practical example:
I have 4 screens where different pricing infomation is being displayed. At any given time, I have to show a Promotion which is a single image that needs to be displayed across all of the screens with text scrolling across the screens.
Now I'm wondering what the best way would be to achieve this.
At first I was thinking of using one form and to stretch it across 4 screens, while I create 4 'areas' on the form that represent a screen. However when you extend a form this big I'm afraid the text is going to look horrible.
Then I was thinking of using 4 forms and split up the image into 4 different images which are displayed on the different screens. However to get a scrolling text right on 4 different forms, that's going to take some trial and error.
how I can achieve this form of digital signage?
I want to use VB.Net unless this would seem impossible and I have to use other software?

Issue : Is there any efficient way to arrange many independent Windows Forms in .Net? I have to display many forms at the same time in my application. It is a graphic charting application, and the number of forms depends of what the user wants, so it has to be dynamic. Is it possible to arrange it like with MDI Layout ?
Example: For example, if user chooses 12 output chart forms, I would like to have them auto-arranged 4x3 on the default screen. Ideally, User could even choose many target screens among the monitors he has.
Why not use MDI: I do NOT want MDI, since my application is multi-screen and I want to leave the opportunity to the user to put his external output chart windows scattered over different screens wherever he wants. But I would though like to have a default arrangement of output windows, without calculating manually screen and forms width/heights by dividing and stuff (Already doing this, it's a real pain). I would like to spare myself this ant-work and focus on business logic.
What I am looking for: If somebody knows an open source library or tool or cool method that could be great. By the way, I found a very useful and handy tool that could help people having the same needs I am formulating here: It is named AquaSnap, but unfortunately code is not Open Source. PS: Again, I Know how to do it "by hand" and assign monitors to forms. It is not the kind of answers I am looking for.

I've tried this example directly from MSDN:
Dim Screens() As System.Windows.Forms.Screens
and I can't find a way to get a reference to the Screen. I've checked my references and they seem fine but I may have missed something. Anyone experience this or know of a bug?

I have a TextBox with a list of filenames in it. The user is able to change these file names, but I don't want them to enter invalid characters, such as slashes or question marks.
I've tried two approaches, but they are not satisfactory:
1. Detect the key pressed with the KeyDown event:
Use e.KeyValue to detect keys like Keys.Oem5 (= backslash), then use 'e.SuppressKeyPress = True' to suppress the key.Problem is, with different Keyboard layouts, The Oem5-key isn't always a backslash.
2. Filter the text:
Use the TextChanged event and do a Replace("", "") on the text for every invalid character (there's 9 of them).Of course this will create 'lag' with every keystroke, especially if there's a lot of text. Also the text-cursor and scrollbar will jump back to the top-left when using Replace.
In short: I'm looking for a way to detect the character that is being entered and suppress or remove it when invalid.
