Single File To Multiple Subdirectories?
Jun 7, 2009
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

I am trying to save multiple type of objects to a single file, objects are a custom class that I am able to serializable and another object is a word document that is not being able to serialize via binary. Is there a way to save multiple objects to one file using vb, also would it be possible to save files like how a docx is saved, that is a .zip renamed as docx but get access to inner objects.

I have a *.txt file which contains instructions and data, with its own comments (preceded by ! ), blank lines, and each instruction begining on a new line, but occassionally using two lines. Each instruction consists of several feilds seperated by a TAB. Finally each instruction ends in a comma. Only a few different instructions are there (10 different ones) but there are many of each. Spanning a good 2500 lines. Comments and blank lines are obviously of no interest to me. I merely need to read the instructions and the data that follows it.
Now, I have successfully used 'System.IO.StreamReader.ReadLine' to go through it line by line, picking out lines begining with certain strings (first 3 characters of a known instruction). All good, I can 'lift' out the lines of interest and store them, for them to be split up later (seperating their fields into instruction, data, etc..) and then into an array.
The problem is, since some of the data fields in these instructions are so long, it spans two lines, before it ends with a comma. Using the above method, I end up with two array entries for a single instruction, since I have stored individual lines rather than a complete instruction. The only similar situation I can tihnk of to explain this, is to pick out sentences in text, and store each one in a string. Of course these end with a period (full stop) but span two or more lines.
I am hesitant to post an example, since its formatting is rather strange, but it is generated that way from 3rd party software, so I cannot change that for my software application.Perhaps there is no 'graceful' way of doing this, meaning I would have to find a way of 'adding' the second line of the instruction, to the string of the first line. Or perhaps reading each line character by character, literally storing every number/letter until I reach a comma.

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?

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.

But When I need user functionality in this form, I have to create an instance of Class3 to this form.

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 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 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.

I have a form which displays temperature and humidity data for a device in the field. I have multiple devices. Rather than creating a separate form for each device, obviously it is much better to have a single form that I instantiate, pass data to, and display. The devices are listed in a treeview, and when the user double-clicks the node, I create an instance of the form, pass the device's data to the instance of the form, and display the form. All of this works perfectly. However, I have a challenge: If the form for a particular device is already open, I don't want another one opened when the user double-clicks the node.
However, whenever I place logic in the program to check for the existence of the form and only allow another instance to be created if one doesn't already exist, it prevents me from creating a form instance for any other device that I may wish to view, simultaneously. So, I have a dilemma -- allow the user to display the data for multiple devices, including allowing multiple forms to be open for a single device, OR only allowing one device to be displayed at any given time.

Is it better to add just one datasource to your project that holds all your database tables and queries that you use as typed datasets. Or, create a datasource for each individual form or situation where your using the database tables as typed datasets. It seems simplier to have just one datasource but is there a down side. We're talking about @25 database tables/queries.

I've developed a couple of different stand-alone projects, myRibbonRTF and myRibbonCalendar and have them functioning well. I want to tie these together with other projects in a single solution called myMain. When I add these projects to the solution, their forms are not accessible in myMain (e.g. myRibbonRTF.frmMain.Show()). I've searched high and low for the last week trying to solve this and the only nearby solution is to turn the other projects into .dlls and access them in myMain that way.

I have been working with Visual Studio 2005 for about a year and a half but the deployment task was never left to me. So now I'm being asked at my company to build a setup which will prompt to install up to 4 applications, which can be chosen by the user using checkboxes.
All of the 4 share the same dependencies, so I created a merge modules package for that purpose. But I still don't know how can I build a single setup to install these 4 applications.
