How To Combine Multiple Matrices Into A Single One
Jan 12, 2011
I am trying to understand transformation matrices (not just their implementation in VB, but in general) and I've put about 3 full days into this so far. I believe I have the data in my matrices correct. Applying any single matrix to an array of points does a correct transformation.I am wondering if I understand how to combine multiple matrices into a single one.I understand you just have to multiply them together.I took this to mean you just have to multiply each element with its corresponding element in the second to make a third matrix?[code]

I've made a rudimentary program that combines multiple files into one single file. Currently if I combine two .csv files together the output comes out correctly for what I need, which is a coma delimited file. When I try to combine two .csv files into a .xls file it doesn't format correctly (I get all the data separated by commas, but thrown into one column in the .xls file). For this reason I believe I need to add a delimiter.I'll post my code below.

I had a related question running on this in a different thread,but I was told to start a new thread since the original had gotten off the original topic. I am trying to scan multiple pages from an Automatic Document Feeder Scanner and combine them to a singlemulti-page tif file. I am using two different third party libraries to do this.The first library I am using is to scan the documents. It saves the files to the local hard drive as single page tif files. This library returns the file-names as they were saved on the hard drive. This part seems to be working as advertised. The sourcefor this including a video on how to use it is at:
Dim FileNames As Collection
Dim FileArray As New List(Of String)
Dim Mergename as String

Say I have a code with 3 methods that do some pretty intensive work. Would executing these methods on 3 seperate threads be faster then executing them one after the other on a single core cpu? And what if it's a dual core or HT?

How do I combine multiple files into the one file with a new extension. No need to be compressed. So I avoid Zip or similar solutions. (Actually don't want to add third party solutions into my application.)

I have three arraylists (datasets and subsets) that I need to combine into one arrraylist so I can databind it to a repeater control and then present data to the user. As far as I know, you can only bind the repeater with one datasource (please correct me if this is wrong) that's why I'm combining these arraylists.Each arraylist has an ID from the database which I can use as a datakey to keep the data aligned. How do I combine these lists?

Now I am needing to add a second table. For instance, my second table "EQUIPMENT" has a field called "DESCRIPTION" that I would like to add to my dataset. The "WORKORDER" table has a field called "EQNUM" which is what the "EQUIPMENT" table uses as the primary key. how to combine these into one dataset?

Each table has 100 columns, and first column is primary key. Now I need to read data from these five tables so that I can export it into Excel file.

My project contains a DataGridView with a SQL Database Table called Shows. This is a list of TV Shows and I want to apply several filters to it. So I have several different columns to apply the filter to.
1. Completed (bit)
2. Hide (bit)
3. Seen (bit)
4. Genre (nvarchar)
Currently I am using RadioButtons to switch between the queries, but I want to be able to have several filters applied at the same time with CheckBoxes.

I want to combine multiple lists of items into a single list, retaining the overall order requirements. i.e.:
1: A C E
2: D E
3: B A D
result: B A C D E
above, starting with list 1, we have ACE, we then know that D must come before E, and from list 3, we know that B must come before A, and D must come after B and A.If there are conflicting orderings, the first ordering should be used. i.e.
1: A C E
2: B D E
3: F D B
result: A C F B D E 3 conflicts with 2 (B D vs D B), therefore requirements for 2 will be used.
If ordering requirements mean an item must come before or after another, it doesn't matter if it comes immediately before or after, or at the start or end of the list, as long as overall ordering is maintained.
This is being developed using VB.Net, so a LINQy solution (or any .Net solution) would be nice - otherwise pointers for an approach would be good.
Edit: Edited to make example 2 make sense (a last minute change had made it invalid)

I have multiple datasets that I would like to combine into one. There is a common ID field that can be associated to each row. Calling Merge on the dataset will add additional rows to the dataset, but I would like to combine the additional columns. There are too many fields to do this in one query and therefore would make it unmanageable. Each individual query would be able to handle ordering to ensure the data is placed in the correct row.
For Example lets say I have two queries resulting in two datasets:
SELECT ID, colA, colB
SELECT colC, colD
The resulting dataset would look like
ID colA colB colC colD
1 a b c d
2 e f g h

Is it possible to have a single class reside within two name-spaces and how can I do this?
To clarify: We have a class library (let say root namespace is classLib1), which has grown over time (more classes) and I want to logically group classes into different namespaces. However some of the older classes need to be grouped into these new namespaces (e.g classLib1.section1) and doing so will break legacy code in other assemblys that use this class library. So I want to be able to refer to a class using both name-spaces until we can phase the old ones out.
I can't find any information on this, which suggests there is a reason that people would not want to do this!?!

My program has two forms which get data from the same data source. After binding controls to tables and fields on both forms, I noticed each form has it's own apparently duplicate DataSet. Is it standard practice for each form to have its own DataSet even though they use the same ConnectionString and connect to the same database at the same time?

I originally developed a simple application software [VB.Net + MS Access] (Lets call this project A) but now I want to include more functionality in it. I have an encryption/ decryption software utility (Lets call this project B ) and a Text to speech generation utility(Lets call this project C) . That is, I want to add Projects B and C to project A. [Such that clicking on the main form of project A calls a form from project B or C as desired].In solution explorer, I right clicked--Add Existing Project--and added both the above mentioned projects 1 by 1. (Added B and C to the solution explorer with the already present A).As the application software's (Project A's) main form is the main form of my project, I want to have a menu option on the main form (Of Project A) so that a user could click on one of the menu options and the main form of my other projects ( Project B or Project C or Encrypt/Decrypt or Voice Generation) should open by him doing so. To this effect, I tried the following:
1. I dragged the form simply from one of the projects (From B or C ) into the folder of my Application Software (Project A).This generated a lot of Build errors and the Voice Generation utility (Prj. C) would not work like this.
2. Tried to reference a dll, however the authors of Projects B and C did not include a dll in their projects.
3. Now I came to know that to call a form residing in another project folder or even another folder within the same project, you have to give a path for the form. HOW DO WE DO THIS?
As you can understand, I cannot copy the entire code of the 3 projects here....I will try attaching my project here though..Here it is: http: rapidshare.co...MY_Prj.zip.html[Dear Administrator: The downloading option on the webpage does not allow files bigger than I mb, thts why I used an external link]As I said, in the application, Project A is TMS.NET ; Project B is EncryptFile and Project is C.I encountered a problem while adding project C [spoken word], so the project contains only projects B and A. I will try to attach project C seperately.That is, TMS contains proj A+B and Speech contains C.

I've written an application with about 30 forms and am almost ready to publish, my biggest concern though is that i'm not sure if its a normal thing to do having all these forms and hiding, disposing and showing forms throughout the use of the application.I've toyed with the idea of converting to a MDI Child / Parent interface as well as having one form with lots of subcontainers that are hidden and then hiding / showing them as the navigational buttons are shown.Ive worked on this application for about 8 months now, but would be happy to rewrite the interface and appearance of it if i know that it is not generally an acceptable practice having forms flashing open and closed while navigating through the application.

basically im looking to have two textboxs with 3 buttons
TextBox1.text contains the path to the new file and
TextBox2.text contains the path folder to subdirectories
i have everything i need working, haha i know not much, this is only my second day with vb.I just needed a button now to carry out the function of copying the file i tried using simple file copy but i had to specify a file output in that and it only gave me option to copy it to one directory.For instance
C:index.php TextBox1.text <- loaded in from button 1
C:www* TextBox2.text <- button 2 loading subdirs
now i need a button 3 that would carry out the function of copying textbox1.text to all subdirs in textbox2.text.i thought i would have been able to use simple copy as stated above with wildcard in my program but no joy
