Insert A Password Concept In Visual Basic?
Mar 3, 2011My responsibility is to build a vb.net function that when a scanner scans an object, it would take the scanned string and call a stored procedure to get a row of data that match that scanned string and pass the data row to an application that would print out a label. below is my vb.net and sql server stored procedure script 1. Do I have to come up with a public class in order to store my row of data to pass it on to a different vb.net application that would take that data row and print out a label? 2. In my stored procedure, how would I return the founded data row to the vb.net function?

Convert Vb6 App To .NET Concept?
Feb 4, 2009(i dunno what title that describes my question better) well, i'm new in this .NET box. i used by Vb6. and now i want to convert my vb6 app to .NET concept. well now i'm stuck with DataGridView, seems like this control is an "all in one" control and memory eater too. well what i want is to have 2 combobox column in datagridview. say as cboGridID and cboGridDesc
while i type in cboGridID in a row, the cboGridID is dropdowned and select the item which is by Autocomplete, while in cboGridID is active i want the cboGridDesc dropdowned too, and select the item by the same index in cboGridID. and vice versa if i type in cboGridDesc
CONCEPT - Control The Message And The Ads
Nov 7, 2008A commercial application we are selling can display a User control written in VB.Net in the interface. I am writing a vertical strip that will display some of our ads to our customers. I would like to be able to control the message and the ads. My idea is to upload an XML file to our server, then have the Vb.Net add-in (user control) download the XML file to a temp location and display the contents as advertisement. 1. Is that a good way to do this? I am open to other suggestions. 2. Is there a way I could embed javascript inside user control? I want to be able to animate the text displayed if possible and I dont know how to do that in Vb.Net user control.
View 4 RepliesReplace Registered Dll Concept?
Jul 22, 2009I am replacing a VB6 application with a rewritten counterpart in VB.Net. In the VB6 app there was a 'control' application which presented a form to the user and allowed them to select a 'client' from a drop down list. Selecting a client caused the reading of an ini file which set client-specific parameters, including the program names of several dlls, which were also written in VB6 and registered on the subject machine.
For example, each 'client' had a different letter format, and the letter was written by the selected dll. This made everything late-bound, but there is only one user. Most of all, it made it convenient to continually update individual letters by updating only that dll, and dropping the dll on top of the old one. Thus the (clerical) user had only to be told to save this file to the usual folder. I could have compiled everything together in one exe, making my updates larger and more complex.
In re-doing this in VB.Net, how should I replace this sort of approach?
I could tie everything together in one big project (and compile it to an exe which is the large update I was avoiding). Should I just do that? If I continue with the approach of having my client-specific (.net) dlls compiled separately, does this make sense in the .Net world? How do I call them? Do they need to be registered as they were before? What's the right way to do this and still give me the flexibility I had?

Oct 29, 2010I am having difficulties grasping the concept / context of two dimensional arrays. For the assignment I am working on I am required to use radio buttons to allow a user to vote if they like or dislike an item from a combo box. The contents of the combo box have been populated through the IDE via tht item property.I understand how to set up my rows and columns, which will be, (0 to 4), (0 to 1). The trouble I am having is how to record and display the votes and have them correspond to the selected item from the combo box. Can anyone give me an example of how something like this works?

View 1 RepliesPossible To Achieve Performance Tuning With Same Thread Concept?
Apr 26, 2011We have developed a vb.net application using multi-threaded listener concept and a dedicated thread for each folder to monitor. With that we simultaneously keep track of the incoming files in each folder.Currently, we are facing an issue whenever we receive multiple files of bulk volume, parallel processing of the files getting delayed with thread concept or failing sometimes.We need to implement the same logic with some other concept avoiding multi-hreading. Or is it possible to achieve performance tuning with the same thread concept?

Duplicate Concept, Industrial Simulation Program To VB Conversion?
Jul 19, 2009I am trying to convert an industrial simulation program to a VB program There is one hard concept that I have problem with, it is called "Duplicate" Ex: When 1 person pass the duplicate block A, then 2 persons comes out, (that person is cloned). 1st person goes path 1, has delay time of 1 hour. 2nd person goes path 2, has delay time of 2 hours. At the end of the 1st hour, 1st person arrives at the detour, at the end of 2nd hour, 2nd person arrives at the detour, but 1st person already moves on to the next task for an hour.
So you can consider them doing their separate tasks simultaneously. Then complication comes in when somewhere down the path, 1st and 2nd person pass another duplicate B, then total of 4 persons will run into their own separates paths and delays. Then they will come back to the starting duplicate block A, thus creates total of 8 persons and follow the same path above again.
Until some condition has been met (ex: total number of persons pass through duplicate B), then all of them will leave the system.Anyone has any idea what is the best way (logically easy to follow) to program the concept? I hope I explained it clearly. It's unfortunate that MSDN doesn't allow attaching image or video.

View 3 RepliesWinform Application Based On BackgroundWorker Thread Concept / UI Update
Jan 26, 2012I have build a VB.Net windows application which does uploads data into database and basically updates two controls:
1. A textbox which is constantly updated with one line per database record upload.
2. A label which keeps track of the count of database record uploaded.
I have used BackgroundWorker thread concept, where the thread's bgwWorker_DoWork() method contains the business logic for upload and bgwWorker_ ProgressChanged() updates the 2 UI controls based on uploads.But the issue I am facing is that I do not get complete updates on both the UI controls. Sometimes the thread bypasses update of textbox and sometimes of label. I could resolve this issue by adding System.Threading.Thread.Sleep(25) before each UI control update code.[code]
Request For Peer-Review KeyedBindingList (Of TKey / T) Generic Collection Concept
Aug 18, 2011There are a lot of different generic collections available, so the wisdom in creating a new one may be questionable right from the start.However, I often find myself wanting the same features from my custom generic lists, but cannot quite find all of those features in an existing object; namely, I would like to have a generic collection which works like a List or Dictionary (much like the System.Collections. ObjectModel. Keyed Collection(Of TKey, TValue)), but also works like a BindingSource does when it is bound to an ADO object (that is, it supports full sorting and filtering as well as currency).A feature I almost never need however, is transactional adds (the BindingSource's ability to 'cancel add-new').Again, with so many existing collections out there, I should take a moment to go over the reasons why none of them quite meet my needs.There is the System. ComponentModel. BindingList(Of T) which would provide some of the functionality of a BindingSource, but has strict requirements about the type {T} implementing IComparable in order to support sorting, and does not provide filtering (it is not an IBindingListView).It also only maintains a base item list by index, so does not provide keyed access.We could use simple databinding with a custom list inheriting from System.Collections. ObjectModel. Keyed Collection(Of TKey, TValue) bound to a BindingSource, but again TValue would have to implement IComparable to support sorting and we would still not have filter support.So to get all the features I was after, I decided that the best thing would be to create a new generic collection object which implemented IList, IDictionary, IBindingList, and IBindingListView (along with a few others) and would be capable of serving as a simple list, or as a binding source while providing full sorting and filtering over any newable object type.
To that end, I've created the KeyedObjectModel which contains the KeyedBindingList(Of TKey, T) generic collection/binding source. This collection can be used as a typical list, or as a binding source (you do not need an additional BindingSource component between the collection and UI controls, although you could certainly have one).Various constructors are provided in order to initialize an instance of the collection as either an enhanced list-dictionary, or as a complete BindingSource.Any object that has a public constructor which takes no arguments can be used at type {T}, providing that the object has a property of type {TKey} which will contain unique values for each entity in a given collection.If the object implements System.ComponentModel.NotifyPropertyChanged then the collection will also bubble up property changes on the current item to the collection's CurrentItemChanged event.An implementation of IComparable on type {T} is irrelevant because sorting and filtering are performed on the property values of {T} based on the type of the specified property.The current design of KeyedBindingList(Of TKey, T) is in an 'alpha' stage.The class is mostly complete from a feature implementation standpoint, however, the code has not yet been optimized and the base collections of values, keys, and view are being maintianed in generic lists of their own, rather than raw arrays.However, even without performance tuning, the collection appears to be performing quite well, up to a few thousand entries, given the amount of flexibility and funcitonality it provides.At this stage, I would really love to get some peers to try using the compiled DLL and beat up the collection a bit.Once the code has been proven and optimized, I will publish it as an example.It is a fairly complex class though (currently made up of eleven or so partial classes) so I don't really want to post the code until it has been optimized.

Checking AD Password - Create A Password Change Form For My Company's Vendors

It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.
