I save the following six individual rtf files in my application and now would like to combine them into one RTB control on a form.
rtbC1.SaveFile(selectedfolder & "" & "FileC1.rtf")

View 5 RepliesI am currently using windows media player as the control I use which plays media (video's and music). It is great and does everything that I want it to apart from play flv files. I am actually desperate to find a control which does this now. Windows media player is brilliant as it has visualizations etc. Does anyone know a control which plays flv files, which excludes realplayer as that control is bad.
View 1 RepliesI'm a long time VB.NET developer and has recently switched to C#. I found out that some of the built-in VB.NET functions (which predates .NET back to 6.0 and BASIC itself) such as the String.Left, or Right, or advanced functions like saving to the registry (SaveSettings and GetSettings) are noticeably absent. What I did was create a new project in the same solution with VB.NET as its language and recreate basically all the functions I need that are available in VB.NET. And then I just call that to the C# code I'm writing.Since compiling the code in .NET pretty much boils down to the same CIL, it shouldn't matter performance-wise what language I wrote the code in or whether I mix C# with VB.
View 4 RepliesI'm trying to write 2 extension methods to handle Enum types.One to use the description attribute to give some better explanation to the enum options and a second method to list the enum options and their description to use in a selectlist or some kind of collection.You can read my code up to now here:
<Extension()> _
Public Function ToDescriptionString(ByVal en As System.Enum) As String
Dim type As Type = en.GetType
Dim entries() As String = en.ToString().Split(","c)
[code]....
So my problem is both extension methods don't work that well together. The methods that converts the enum options to an ienumerable can't use the extension method to get the description.
I'm working with a third-party library interfacing to an old database system. There's a method - CallProg that calls a "stored procedure" (for lack of a better translation - any Pick users in the crowd?). However, instead of doing something like this:

I have 3 textbox's and 1 dropdownlist and I am trying to combine all that data into one string. Here is what I tried but is not working:
Private Sub FullAddressTextBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles FullAddressTextBox.TextChanged
FullAddressTextBox.Text = AddressTextBox.Text & " , " & CityTextBox.Text & " , " & StateDropdown.text " , " & ZipCodeTextBox.Text
End Sub
My goal is to combine these simultaneously as whoever is filling in the data or after I hit my submit button, if so it has to occur as the first event.
I think my problem has to do with .text after the statedropdown, Is it suppose to be .tostring?

I have two (actually many) .png images in my application. Both have transparent areas here and there.I want, in my application, to take both images, combine them, and display the result in a picture box. Later I want to save the result through a button.So far I managed to find the two images and combine them, but it seems the transparency thing won't work. I mean, if you put one image over another, only the top image is visible as the result because, apparently, the image's background is a plain white box. Which is not. Here is a bit of my code:
Dim Result As New Bitmap(96, 128)
Dim g As Graphics = Graphics.FromImage(Result)
Dim Name As String[code]....
resourcesPath is the path to my resources folder. Bases is a folder in it. And Name is the image's name.

Let's say I have 3 tables: carts, baskets and eggs where a basket can contain many eggs and where carts contain many baskets. Each basket has a foreign key that maps to a cart and each egg has a foreign key that maps to a basket.I need to return a table that contains these 3 columns:Cart Name | Count of Baskets in Cart | Count of Eggs in Cart.Each table is an EF and I'm using linq with VB.So far, I have 2 queries: one that returns the columns Cart Name and Count of Basket and another one that returns Cart Name and Count of Eggs. How can I combine these two result tables so that I get the results in one table?

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 have a set of objects that I'm returning via a Linq to SQL query. I'd like to modify the query so that I return a set of objects that are combined only when one of the fields match. The relevant columns of my Products DB table are CategoryID and Quantity. I'd like to combine the fields so that if the CategoryID is identical, the Quantity fields are summed up. However, I don't just want the sum - I need an object that has all the common fields (assume all other fields are identical for the query) so it appears as only one object of type Product. Is this possible? (I'm using VB.net - but open to solutions that include database views, partial classes, etc)
View 1 RepliesHere is a complicated, but possibly dumb question concerning adding projects together in the IDE in order to increase performance and share memory at the same time.I have written two distinct exe's. The first exe (file processsor) operates using three timers to perform communication between a hardware OEM proprietary ComServer and file output from the second exe. The second exe (work generator) simply outputs files on hard disk so that the "file processor" can process the commands in the order given. The first exe was written as a "background processor" to the second exe in a stand-alone fashion. There is a need to communicate data between the first and second exe that is time sensitive. The ComServer called by the "file processor" only allows one port to for communication to the hardware device that is a USB. The "file processor" is capable of extracting the data required but the existing technologies, such as RPC, IPC are too slow and or full of pitfalls. Microsoft's Memory Manger has found it easier to create multiple instances of the proprietary ComServer and assign the needed memory to the calling routine so that it can "scoot" memory easily in the garbage collection feature of the operating system. What this does is cause the mullitple instances that are created to "gang up" on the device either slowing its performance down, or causing time outs. [The second process is a custom 3-D graphical CAD/CAM. The first process is a machine interface. Although hind-sight is 20-20, it seemed more ideal to write this background or file processor independantly, as then it could communicate with existing as well as a custom CAD/CAMs.]
Simply writing the first processes' code into the second slows down the second process as a result of all the timer interrupts looking for work to do. (Mouse is squirrely, screen refresh is slow, etc.) I am only guessing here that the operating system's service of the more complicated single memory location is somehow interrupted more frequently for a larger project, than two smaller independant projects running seperately. I only know what I observer here. Interestingly, the two smaller projects running seperately seem to run fine.
Now for the dumb question. Is it possible to merge the "file processor" with the "work generator" in the IDE such that each process runs as independantly as two distinct apps, but at the same time, make it possible to share memory via one Module1.vb? So far, I cannot find a way for the "file processor" to see the "work generator's" Module1.vb, regardless of how many PUBLIC statements I issue in the code. In other words, what would be the steps after File->Add-> Existing Project to cause the "file processor" project with a form to start first, then drop to the background, followed by launching of the "work generator" second where each process shares the same Module1.vb?.
If this could be done, say through a compiler statement, or whatever; then this could make the Memory Manger folks happy, and provide for the speed required to operate real world processes? Basic computer science suggests a simple processor LD instruction could make data available to any application within a few clock ticks. Microsoft now longer allows direct memory access, or the ability to carve out a "stay resident" dll in memory where a memory location can be called for quick distribution information to all apps with just one call to a device.

I'm making a program in which there is a form and when opening this form it automatically checks the internet for a csv file and reads the data from it.
the csv file consists of 2 items i need "Provider name , Provider smtp" example:
==
Chello,smtp.chello.nl
Het Net,smtp.hetnet.nl
==
I've got the part working that when the form loads the online file gets read and the data is shown in a combobox. Only it shows the whole line like 'Chello,smtp.chello.nl'.
What I want (and can't seem to get working) In only the combobox the words before the comma and in a invisible textbox the corresponding smtp line. Ergo when I select option number 4 the right smtp is put into the invisible textbox.
