Objects - Display Some Test Extra Textboxes In A Dimmed / Transparent Type Of Fashion
Feb 9, 2010
I have a form that displays data. What I would like to have is a button that when pressed will display some test extran textboxes in a dimmed/transparent type of fashion. I can get that using another form, but would like to do it without the second form.

I usually can find anything I need on google, but this isn't the case this time. I have a com object that is a display control, it displays images from another software that are retrieved from a camera. I am trying to overlay graphics on this image for reference to an operator. I have found how make a picture box image transparent but not over another object. The images are PNG and are set to transparent.

I'm doing a new interface for my app and I'm using MDI forms. On the parent form I want some objects like Labels and ToolStrips with Transparent BackColor but even when I change the MDI Client BackColor to Color.Whatever or the BackgroundImage and apply a Transparent Object it just doesn't get the color behind it but gets DarkGray instead .
I changed the MDIClient.BackColor with: Me.Controls.OfType(Of MdiClient).First().BackColor = Color.Red

I've written a for loop to generate several new text boxes and numericUpDowns when the application is run.
The text boxes / numericUpDowns are generated with a 2-dimensional array. My question is: How do I handle when the text boxes / numericUpDowns are modified?
If you would like the code, just request it and I'll add it here.

I am looking for a VB control that operates as a more or less transparent or semi-transparent ruler or bar that can be scrolled up and down the form over an invoice or letter, so that the user can see what is under the ruler/bar and thus stop scrolling when he reaches a certain point.
To give a bit more detail of what I am looking for - such a bar is used when someone is setting the focus on a line of a long list of items so that they know where they are all the time. Most people would use a ruler on a paper list to keep track of how far they have progressed down the list. It would be nice though to have the "ruler" or bar as semi-transparent so that the user can see under where he is at on the list or form.

So I have my main form (Form1) and I have a module called globalMod. On start up, Form1 loads, and globalMod contains functions and global variables (using Friend). I need to be able to have a function inside of globalMod edit a label/text box/etc in Form1. I tired Form1.object.Text = "content" and it doesn't do anything, even if I update / refresh the form.

I'm writing a program in which I want to list the values of some of the properties on every control on every form in the application. I can do this for simple controls like Buttons and Labels, but am having a problem when it comes to a complex control like a ListBox. I know how to extract the data when I laboriously code each ListBox individually. The problem is how to do it when it's a generic object buried inside two loops

I have a transparent layer on the top of a form. I need to display only some part of that transparent form.
-edited- If you think of a map and traffic signal icons displaying on the map. There are a map image layer and a traffic signal icons layer, which is tranparent except icons. if you move the map location, the traffic signal icons should move along with. if the certain area of map does not appear on the screen by moving, corresponding traffic signal icnos should disappear as well. This is what I am trying to do here. Moving the trasparent form is straightforward, but I need to hide some portion of that transparent form.
[Map]
[Traffic sig] here I need to show "fic s" part only.
This is for a very small image.

I have two separate web services, the first configured to extract data from a live database, the second from a test database.
When consuming these web services from an application the object returned is a MyMessageData class which is defined in the web service.
In the application I would like to instantiate a empty the MyMessageData (from the live web service) and then use a configuration setting to decide which web service to retrieve the actually data from.
This does not work for test because the application does not see the instantiated MyMessageData class from live as the same type as the MyMessageData that is returned from the test webservice. [code]....

I need to test a string of text that needs to contain a certain type of char values. The known is allowing of a-z,A-Z,0-9. But the variable (which will be coming from a database field) will be the allowed symbols. The allowed symbols will look something like:!@#$%^&*()
So using regex, how can I check a string of text to make sure it ONLY contains a-z,A-Z,0-9 AND the allowed symbols as shown above? Remember, the allowed symbols is dynamic at run time so I need to somehow be able to plug that in to the method at run time.
The following examples would be valid using the above symbol string:
Test1234%
Test1234
The following example would NOT be valid:Test1234%_

Currently, I have a RingBuffer which is run by a producer and a consumer thread.In looking for a method of terminating them orderly, I thought I'd use a flag to indicate when the producer had finished and then check that flag in my consumer along with the number of ring buffer slots that need to be written. If the producer has finished and the ring buffer has no slots that need to be written the consumer can terminate.However, if I artificially lengthen the time the producer takes by inserting a sleep, the consumer does not terminate. I believe this is a consequence of the semaphores being used.Here is the code I'm working with. Notice that the program will "hang" after all slots have been written. The producer terminates, but the consumer "hangs".[code]

OverviewThe fastest way to read or write Xml documents in a linear fashion is to use the XmlTextReader and XmlTextWriter classes in the System.Xml namespace. If read- or write-only forward-only access is too limiting, however, the System.Xml.XmlDocument class provides the ability to easily modify existing documents (adding, removing, or modifying elements and / or attributes) and leverages the powerful search capabilities of XPath.
Getting StartedThe XmlDocument can load Xml from a string in memory, from a URL, or from a file path. There are two methods that enable this functionality: Load and LoadXml. To load a document from either a URL or file path, use the Load method. Following is an example of using the LoadXml method to load an Xml document from memory. (NOTE: we will be working with this particular document throughout this article)

How find an object's type when it is a subclass of another object and I only know the string value of the object's type's name. I created the following classes:
HTML
Public Class word
End Class
Public Class noun
Inherits word
[Code] .....
Then, in my code I create a new properNoun and check to see if it is a properNoun, noun or word:
HTML
Private Sub checkTypes()
Dim pn As New properNoun
MsgBox("Is a properNoun: :" & TypeOf pn Is properNoun) 'TRUE
MsgBox("Is a noun: :" & TypeOf pn Is noun) 'TRUE
[Code] .....
I correctly see that pn is a properNoun, a noun and a word. The problem is, using 'GetType' to check pn against a string value, I can only see that pn is a properNoun, not that its parent classes are noun and word. Is there a way to check pn against the string value "noun" or "word" and get back a positive result, indicating that pn is indeed a noun and a word as well as a properNoun?

Which of the VB controls is best suited to show images in a strip like fashion from an Image Array?I have an Image Array. I would like to display the images in the array to the end-user in a control.The control should should apear like a scrollabel list. I guess something like silverlight does.When the user sees and selects an image he/she wants to view, it is selected by clicking on the thumbnail and appears in a picturebox.
