I've trying to get the runtime path of an OLE Object stored in a database. The code below is used to get the Ole Object (In this case a PDF document).

Currently, all that's being returned is a pile of bytes of which I have no clue of how to handle.I need to somehow find the path at runtime of this PDF file in order to use it as the value of the 'src' property (string) for my Adobe Reader control.
Ok i need to make an object in this case a picture box draw a line to another picture box with the shortest length while avoiding other type of objects such as labels i am not sure how to do this but so far i have come up with

I'm working on my first web service and I'm having a blast doing it. I've got a client that talks to the web service installed on a test server. I'm ready to release the code and I realized that when I created the web reference I gave it a path to the web service. I do not want to hardcode this in my program, so I'm looking for a way to dynamically change the path to the web serivce.
What I've done is --
1. Create a web reference to the Web Service:[URL]
2. Built my client using this web reference
3. ... not sure where to go from here.
Basically, I want to stash a value in the app.config file and, on load, use this URL as the web service. Can someone point me in the right direction? There has to be a property I can modify at run time to point it to a some location.
I'm writing a function like this:
Private Function mostRecent(ByVal folder As Directory) As Date
'function to convert the given directory param as a path obj
Dim foldPathStr = Path.GetFullPath(foldPath)
[Code].....
I'd like to fill in that commented line with a built-in command, if available. If not, guess I'll change the parameter.
How can i change the background image during runtime? so far, i have an openfiledialog that grabs the location of the .png or .bmp file and then i have this below it[code]...

This creates a folder. How to create a folder by giving its name and path at the runtime?
not like changing the code and running it again and again

I have created a data source connection to an access db by using the wizard in vs2008. I have then used this as a data source for crystal reports. My user would like to put the database on a network and reference it there. Is there a way to set a new path for this data source during runtime?
View 4 RepliesHow can I programatically find the path and file name for an embedded object in an Excel worksheet? I know I can right click on the object and select Packager Shell Object and then Properties to find the information

The tree is obviously very deep. Does anyone have an algorithm to create this into a jstree, series of "UL" and "LI".

My thought is to eventually make this into a jsonp web service so I can use jstree to build a tree, but for now im just trying to understand the logic necessary to parse this correctly.

I get this error in this code:
Private Sub Request_Stuff_button_Click()
Call Main.createObjects
Call My_Control.requestStuff
End Sub
at the 'Call My_Control.requestStuff' line.The 'Main' module looks like this:Public My_Control As ControlObject
[Code]...
right before the line that gets me the error, x gets the correct value right before the error happens which means My_Control is definitely an object and is definitely not nothing.
I have an object, o, and a type, T. I'd like to use reflection to change object o to type T at runtime without instantiating it.The equivalent at compile time would be:
Dim p as Point = Nothing I know how to use Activator.CreateInstance to create an instance at run time that is equivalent to: Dim p as New Point()
But i don't want to do this. I have no knowledge of the type's constructor parameters and some types don't have a parameterless constructor. eg. Font. So, to sum up, I'd like a way of performing the equivalent of: Dim o as T = Nothing
In case you're wondering why I'm doing this, it's because I'm using a PropertyGrid on a form to edit types. If this is the first time for editing, say, a Font, then passing an uninitialised Font to the PropertyGrid makes the grid display the default values.
I tried 'o = GetUninitializedObject(T)', but the PropertyGrid either wants a properly initialised object or an object, with a defined type, set to nothing.
I've actually solved my particular problem here: how-to-use-the-property-grid-in-a-form-to-edit-any-type
, but i'd still be interested to know how to assign a type at run-time without the use of a wrapper class (which I was lucky enough to be using).
I am developing a fairly large database in VB 2010 as a record keeping. There are 37 tables with some many-to-many relationships in there and some collections too but it all gets loaded into a List of Person object.It is a record keeping database for a youth charity including Personal data, lists of events attended, Medical data, Duke of Edinburgh (UK award scheme) etc The main form is a tabbed form with the linked data from other tables and collection on various tabs
Is it possible to bind a runtime object to a control? if it is possible my life becomes very simple.I can get basic data working with DataSet binding and navigation but the ralationships may prove too fiddly to link as datasets.
Is it possible to construct the name of an object (in this case, a Panel control) at runtime?
What I want to do is change the Backcolor of one Panel that is a member of about fifty panels. I can get the string of the name from the Sender in a RadioButton CheckedChanged event. So what I want to do is something like:
PanelName = sender.parent.name & ".BackColor"
PanelName = Color.Red
(I realize that the syntax above is invalid. I'm just using it to try to get the idea across.)
I can do what I need with big, fifty-element Select Case blocks, but the code is so repetitive that I was hoping there was a more elegant way.
Trying to create an application where the objects in a form are created during Form.Load depending on the content in an ini-file.The objects I have in mind are textboxes and labels for a start.
View 5 RepliesI want to create a new object of a class which is not predetermined before run-time. Something along the lines of:
[Code]...
TabMenu.Controls.Add(btnOrder)
'btnOrder.Parent = Me.TabMenu
'btnOrder.Location = New Point(300, vertloc + 20)
'btnOrder.Text = "Order"
'btnOrder.Name = intCount.ToString & "OrderButton"
So I have my program make buttons similar to the above, I'm going to have a button created at the point were the cursor is, as long as the location is a valid one. Now I have two questions.
1) I want to use the following code to be able to move around any of the new buttons that I place down on the form.
' a quick TY to Ronald_Hare here on the forums for posting this little snippet, as it does exactly what I want.
Private oControlOffsetPoint As Point
Private Sub Button_MouseMove(ByVal sender As Object, ByVal e As
[Code].....
2) I also want to be able to change the back color of the button based on a number of boolean flags I will be setting. Is any of this possible without completely mangling things? I'm hoping there are some easy options for setting a button made on runtime to use a number of premade subs or functions.
On a side note: This does not need to be exclusively a button. a picturebox or a text box would probably work just as well for what I want to do, but I like the look I can get with the button atm.

Dim x As Integer = 0

As you can see, i can retrieve the tag of the button (which is created at runtime) without any problems, i've made a temporary msgbox to show me the value of the tag, just for testing purposes. What i do have a problem with, is retrieving the tag of the individual web browsers, how should i do this?
Next issue, how would i code for my buttons to show the web browser with the same tag as the button that's just been clicked?

I am having issues adding a custom object to an arraylist at runtime.
Details of what Im trying to achieve.
My object is Fixture which represents a light. My light has the following properties:
Name, isMover, HighlightValue, UserNumber, Channels.
Channels is a dynamic arraylist which lists all the different channels of the fixture. A channel could be the lights colour or its intensity. A channel has the following properties:
Type, FeatureGroup, Value, Universe, Address, Slots and Offset.
Slots is the same again, breaking down to another ArrayList with more details.

I am using reflection to get an object's type, or for this issue an object that has instance properties type, at runtime and then I need to change an existing variable's type into that newly found type. Is this possible? For example, the following code does not work in the line indicated within:

but it gives an error (nullreference exception was unhandled) hereby the code;

This is a more elaborate explanation of my code. If you observe that in the Eval function I have tried to evaluate Fval(abc). Now the object array abc is not declared in the Test class because it existence is not known beforehand. What I want to do is create an object array abc of length 2 and populate it with some values and when Fval(abc) is called then then the value of index 1 should be the return value of Eval fucntion.
