View 11 RepliesScenario:A widget developer codes using HTML and javascript.my vb.net application allows developers to create widgets for other users.in javascript you can call window.external to comunicate with the host windows scripting object and I would like to add a helper namespace with many functions to aid the development of widgets similar to windows sidebar's System namespace.
Problem:So I could allow developers to use Window.External.System but how can I just allow them to access System directly without using Window.External?Microsoft adds a System Namespace to windows sidebar gadgets host window which is just an internet explorer server window.

I want to create a global function to use throughout my application. Let say it's about the connection to the database.My code that i plan to use in my global function is:

I have also tried adding "FixPath()" under Sub On_load() but got same result. Also the reason I have to have these global is because I have around 30 Subs that refer to "Path" Variable.
I want to create a new instance of a class when I click on a button, but I need to interact with members of that class using other controls on the form, so I need the class to have a global scope. I know I could call the new class in formload, but the class creates certain variables that need to be current. If it is done on formload, the variables wouldn't be current, because if the class is created at formload, it would have different info at that time. Surely, there must be a way to create an instance of the myClass from within a sub that is accessible from other subs of the same class.

I am working on a solution that does not name namespaces in code files. Instead it uses the root name space of the project (which is the same across all assemblies). Basically there is only one implicit namespace.
Well, I am trying to isolate some code so that I can run FxCop against it. I explicated named the code file with a namespace to do this. This works for FxCop, but it bricks the entire solution.Visual Studio is now asking me to prefix all uses of the implicit namespace with Global. So instead of:

I need to execute a stored function in oracle or sql through vb.net. I created a command object. Depending on the database type(oracle or SQL) i am preparing the Command text as Select functionName(?,?,?,?,?,?,?,?) from dual; (For Oracle) Adding the parameter values of the function.

In the software I am developing for my A-level computing coursework I want to add a function to export the database (to backup, use in other computers, etc) and later on a function to import databases (that I had previously exported using this function). At the moment I have a SaveFileDialog, and I have filtered .mdb files only (as this is the type of files supported by my application). But How do I select what is going to be saved? (How do I point to the .mdb file that is located in the program's directory?)

I have an XML file and I have a function to which this XML is passed as string. I have loaded this string in Xmldocument and I need to insert few children nodes under one node. This function returns the modified XML string. I want that whenever this function is called, new child nodes are added, currently, It adds child nodes once.Do I need to overwrite the XML file ? If so, How can I replace the node with new node ( with new child nodes added) so that It has child nodes added before the function is called again ?
My code looks something like this:
Dim doc As New XmlDocument
doc.LoadXml(applicationXml)
Dim parentNode As XmlNode = doc.GetElementsByTagName("prList").Item(0)

View 5 RepliesI am looping through all folders on the computer in a background worker. Starting with just the C: drive, the function works perfectly I've been tasked with adding recursiveness to this function to loop through all subfolders within each and every folder.
This is the working code without recursive. Startpath is set = "c:".

EDIT: I was doing some testing and threw in an if check to skip the C:$ folders. Working ok so far and noticed something really strange. It doesn't loop through all the folders in the C: drive. I think it will loop through only the first 2 folders. One is C:Boot so I skip that and the other is C:Dev-cpp. It won't loop through the Program Files, Program Files (x86), or Users.

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?
View 1 Repliesi wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.
