Sending Excel Objects To Subroutines
Dec 14, 2011
As it is right now I have a bit of code that kind of looks like this (a little paraphrased but Im sure you get the idea)[code]I thought for sure the above would work but it still seems that I am missing something, when I open the excel sheet nothing was printed. This would cut down the lines of code that I have in half easily, so I would love to find a solution for this [code]But the excel sheets still do not update with the new information.

I'm having trouble with passing an array between subroutines
I have an array called "lines" which is loaded from a text file and then edited according to a series of checkboxes within one subroutine. Each line in the array is essentially a line from the text file
I then need this array passed to another routine so that it saves to a new text file once the save button is pressed. (in this case just the top 5 lines)
At the end of the section that creates the array i have placed this
From File Edit
Call Savefile(Lines)
The section of code below is from the section once the button is pressed
Save Code
Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Savebutton.Click
[Code].....

I used the tool about 3 years ago to create the classes for a webservice client to send or recieve arrays as complex data. Now i have to update these classes, since there are additional informations, that have to be exchanged. When i use the tool now with the new wsdl-files, it does'nt create the classes for complex data (structur, IGCTMObjectFactory), but only one class for simple data. In addition i have to establish a new client, that sends an array of complex data and receives another array of complex data. I tried to build the classes manually combining the client that sends an array with the client, that receives an array, but I failed.

Do we have unload event for class to release these objects?

just hoping that someone may be able to point me to some information where I can create VBA objects in vb.net (I am using VS2008). For example, I would like to create a new object in VBA with the command (Dim x as Matrix) where 'Matrix' is an object with various properties and methods.

I have created a COM Object via VB .NET and exposed some functions that I wish to call in Excel using VBA. I am currently trying to pass an array of objects as a result to VBA but Excel is complaining the following:
'Function or interface marked as restricted, or the function uses an automation type not supported in Visual Basic.'
I have looked around on the internet and have seen similar issues but not to one I am trying to do.My VB .NET function, which I wish to call in Excel is declared as follows:
Public Function CallArray(ByVal serviceName As String, _
ByVal effectiveDate As String,
ByVal serviceParams() As System.Object,
ByRef ArrayRes() As System.Object) As System.Boolean
VBA is complaining about the System.Objects my question is how the heck are you supposed to pass and return arrays from .NET to VBA. Also the data that will be in the ArrayRes() is mixed type, its not just strings etc, its an array of arrays that can contain strings, integers doubles etc.I chose VB .NET because I assumed it would be possible to map to VBA easier.if System. Object and Arrays in VB .NET is not the way, ie maybe theres another way via collections or lists, then Im open to that. I just need to get this data into VBA.Also I could move over to C# if needs be.

I need to migrate from Excel 2003 VBA to Excel 2007 VBA. When Microsoft introduced Excel 2007 it removed many objects from the previous versions and added some new objects. Also it hid some properties of particular objects. These hidden properties can be viewed by going to the object browser, right clicking any object and selecting "Show Hidden Members". My problem is I need to access these hidden properties. Is there any way I can access these properties. I can successfully migrate from Excel 2003 VBa to Excel 2007 VBA with the same functionality?

I have a website. In it, I have a button which will export some data from a SQL database to Excel. I want to open an excel workbook on the client and paste the data there. This all works fine locally, but when i publish it, I get this error:ActiveX component can't create object.[code]Have searched the net, and it seems the problem is permission related. Can anyone explain to me how to configure my server so that I can use clientside Excel?

I recently added three subroutines to a form, and as a result of adding only the three subroutines, I have noticed some weird behavior in the form and I can't pin down why these three subroutines would cause it.

To detect 'death of player' I am using the mouseleave event of my picturebox background (background1). Unfortunately this triggers both when the mouse enters an 'evil' and the 'points' and ends the game without the player being able to collect points.
The obvious way to solve this would be to swap detection to entering evils.
Unfortunately I am dynamically creating my 'evils' and do not know how to also dynamically create subs to deal with MouseEnter. Here is my code for generating the 'evils'
'The number of evils (asteroids)
Dim evilcount As Integer
'A count for use with comparison to evilcount

I'm struggling with an event related to my communications class.I'm calling a 'DataChange' function via event handler any time I receive new data over my serial connection. I then proceed to load that data into a DataGridView, perform some formatting, etc for the users. I'm getting a ton of problems due to the frequency at which the DataChange event is called and seems to steal the focus out of othert subroutines and functions mid-process.For example, I'll attempt to transmit data back to the serial device. After I format the data, but before I can actually call the Send function from my library the focus is directed back to DataChange and I never actually transmit my data.
Is this a problem best addressed by threading the DataChange related routines, unhooking the DataChange event before a function or routine then rehooking, or is there some basic principle I'm not implementing.

The Visual developer express outline provides hide/plus-minus signs throughout the HTML code, and it does this for Class's, but not for my subroutines in an ASPX file.Is there a way for it to do this, so I can reduce subroutines I'm not working on at the moment? I know I can highlight areas and hide, but it's kind of clunky to do quickly through many subroutines if I have 2k lines and a hundred subroutines.

I have 2 arrays X(n) and Y(n) where n can vary programmatically, no set value. I want to pass these two arrays between two subroutines.
Sub sub1()
...
call sub2(X,Y,n)
end sub
sub sub2(x,y,n)
...
end sub
I want to know how to prepare the arrays for the "call sub2" and how to extract the arrays in "sub2".

have been writing code to replace an old Fortran program. The Fortran program had very organized subroutines which could be called from anywhere in the project. Most of these were relatively small and left a small, easily followed main routine. I'm converting over to VB.net and when I write the subroutines they are all on the same form. Wading through 50-100 subroutines on one form is going to be messy.

I am trying to convert an algorithm to use them in order to save memory. However, I am struggling to achieve error-free code while using "Strict On".
Here is a basic version of the code I am attempting to use.
Code:
Option Explicit On
Option Strict On
Module Program

It works when I do not use the Strict option. How do I improve the code to compile error-free?

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

I find myself calling functions from lambdas frequently as the provided delegate does not match or does not have sufficient parameters. It is irritating that I cannot do lambda on subroutines. Each time I want to do this I have to wrap my subroutine in a function which returns nothing. Not pretty, but it works.
Is there another way of doing this that makes this smoother/prettier? I have read that this whole lambda inadequacy will probably be fixed in VS2010/VB10 so my question is more out of curiosity.

Working on my major project for my last year of school worth 30% and am having issues with getting screen elements (buttons, labels, picture boxes, etc.) to update before or during a sequential sub program or function.
For example, I have a series of picture boxes that require to be clicked on to activate certain commands. Here is the code for one of the picture boxes, picX3Y0, when it has been clicked on:
If picX3Y0.ImageLocation <> imageFolder + hiddenImages(3, 0) + ".png" And imagesSelected < 2 Then
If x1 = -1 Then
x1 = 3

I'm trying to communicate through a serial port with separate subroutines for establishing the connection to the device and handling routine messages. I'm able to establish the connection, but reference to the COMPort in another subroutine fails with a message that the port is closed. I can successfully communicate using COMPort.Write commands within the connection subroutine, so I know that works. How do I pass a reference for the comport to other subroutines?

Visual Studio 2008, Standard Edition VB.NET I have only limited experience using the background worker, and all that I've done with it thus far was fairly straightforward and worked fine.
I am now looking to run a process in a background worker which calls various functions and/or subroutines, but of course it generates an error indicating that it's on the main thread (or something like that - I don't recall exactly, but that was the crux of it).
