I had a large application that I needed to develop into two separate applications with different customer needs. I created a new VB.Net application and copied/imported all the forms and classes into the new application. The new application works but, for some reason all the forms have lost their 3d look, all the textboxes have a flat look now in the new application. It is as if I have lost a setting somewhere that controls the 3d look of the controls. I have checked the properties of each control and they still have the 3d option selected, and cannot see what else could be changed to get the 3d look back.
I need to compute the percentage of games won and games lost. I keep getting errors and it's driving me up a wall. I've changed my code so many times that I don't really remember what it was like when I started.

I m using vs2008 with vb and sqlserver. I just attached a .sdf database file to my project. There is a form to insert data in products table and a dgv to show that data. Everything is working fine, i inserted the data and dgv is also showing the data. But when i tried to see that data from server explorer, thr is no data, table is blank. Then again when i run my project thr is no data in DGV also. So problem is that when i entered the data and retrieve back the data in dgv,evrythng is fine,but when i tried to see my data from server explorer, data is lost. Why data is not comtted to my .sdf ?
I trying to create application that can read loss bmp with bmp constructor, what I mean loss is bmp without header, here the sample of loss bmp (zip is including with original bmp):
Download(you can see the different by comparing the original bmp and loss bmp with hex editor, the different is loss bmp don't have 54 bytes header bmp) Height of image is 126 px and width image is 45 px
my question is how I can preview that loss bmp in picture box? someone of my friend say, its need BMP Constructor to preview bmp properly but he doesn't know the code, please give me the code..
VB 2008 Express edition. I'm pretty new to VB2008, a little over halfway through my first classi am writing a console program to ask the user for the price of gas for 7 days, then to get the average of that price. here is my code so far:
I'm having bizarre performance results of the methods in FileInfo class.I'm using 5 methods of the FileInfo class in the Paint event.The datagridview is bound to the dataset.First the application searches files in the RecursiveSearch. When rows are added to the dataset the Paint event is fired and the rows displayed are filled with extra information from the FileInfo class . In this case the performance is very good. If I remove the DoEvents() from the RecursiveSearch the 5 methods of the FileInfo class become very slow (about 0.25sec for each line of code)!When the search ends, the user can scroll down to see the other files listed.At this point the Paint is again fired. This time the 5 methods of the FileInfo class are again very slow!
Private Sub RecursiveSearch(ByVal sPath As String, ByVal strPattern As String) System.Windows.Forms.Application.DoEvents() Try Dim strFolders() As String = System.IO.Directory.GetDirectories(sPath) Dim strFiles() As String = System.IO.Directory.GetFiles(sPath,
my project is attached. I have a very weird problem with Winsock! I made 1 program with 2 forms. 1st form is the client, 2nd form is the server. Server send snapshot for client. So, client display either Single Picture. Or stream of pictures (to simulate video capturing).
when open 1st window (client) in a computer, and 2nd window(server) in another computer... it connect and display picture without problem just once!! when press "Capture" button again it may reponse or Winsock may loss connection. and when Check "Loop"=> means for stream of pictures.. Winsock loss connection immediatly! I don't know where is the problem exactly! The code attached. Winsock ocx is attached.. see it in the release folder

how many of you out there in the VB.NET community have installed VS2010 SP1 and are experiencing this issue with the loss of intellisense in SQL Server 2008 R2?I'm holding off installing SP1 because I kind of like the intellisense thingy (though RedGate's SQLPrompt 5 is way better - have it at home).So is this pee-ing you off, have you explored workarounds, tries the hotfixes (that apparently don't work for many setups)?url...Please note that even though Cumulative Update 9 (CU9) was released the month there are still people it does not work for..including a coworker using a similar setup as mine (Win7 Pro, x32) This is a disaster and embarassment for MS IMO
I found a win, loss, percentage calculator in the forums. The form has a PLACE FOR INPUT
Team Braves WINS = 96 LOSS 66
a button Compute Percentage and a text box it should read Braves won 59.259 percent of games. The program in the forums does not work. Does any one know how to do this? The math should be wins / wins+loss * 100.
I am trying to code to capture the packet loss on computers, but the only way I've been able to do so was to run the NetStat.exe and the TraceRt.exe processes and capture them to a listbox (using the code below):
I coded this program. It has three forms, when I try to open the [Design] on one of the forms it give me this error: To prevent possible data loss before loading the designer, the following errors must be resolved:
i want to make crystal report of profit and loss statement i have a column of "vr_type" and there are 4 types in it "sale invoice", purchase invoice" now i want that put a 4 formula s where i select that "sum (vr_detail.debit) where vr_detail.vr_type} sale invoice it make Sum of al these types so kindly tell me what formula i should use to get the result in simply i want sum of sale,sum of purchase,sum of expense?
I have an access DB with 3 columns, ID#(Primary Key), Minutes, and Profit/Loss. I'm using the Total feature in access which adds a Row 'Total' to the bottom and shows the sums. How would I get the sum from the 'Minutes' column, 'Total' row, and get that to show in a text box (txt002004Min) ?

I have an application putting new data into a database so I want to use a DataGridView to display the data. I have a timer triggering every 5 seconds and running this UpdateGridFromDatabase() routine every cycle. It works, but I can see my application memory usage going up by 10kB every 5 seconds until my computer with 6GB of RAm & 64 bit Windows 7 grinds to a halt! Can anyone see at a glance what I am doing wrong? I am trying to open & close everything as necessary. I have also dimmed two variables outside - I had then inside previously and it didn't make any difference.
For the past 3 weeks now, we are encountering a sudden loss of table in our database, but with that. our .mdf file is still on its same size before this disaster comes along and again..anyone had encountered or know how to solve this problem.
I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.
.NET developing and have a simple question, i've been stuck on this for a while and searched many forums first with no solution so i'm posting myself. In VB for excel i've used Screenupdating=false to disable the screen updating however now i'm creating a visual studio 2010 windows forms application and its not showing up as a property. Here's the code i've tried.
just wondering if it is possible to add a method to all forms in my project without having to do it on one form and Inherit all my other forms from that one
I'm using VB 2010 and need to multiply 2 user input numbers in forms, so basically: TextBox5 = TextBox2 * TextBox3 That obviously didn't work but it shows what I want it to do.
I'm working on a website where we'll be getting a lot of videos to be uploaded. To keep things simple and secure, I'm just writing VB.net windows app to suck all the files in a directory in, allow you to set some options, and start the encode by spawning a new FFMpeg process.
I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?
I would like to know if its possible to start up a second windows forms inside the parent form. Ex: A button is pressed and a new form is showed. I would like to keep that new form inside the parent form, and have it not be able to go outside the parent form.
I am writing a program for my A-level coursework But for some reason I got this build error this has never occurred to me before, I have no idea why I can't use string for the name of my form.
a program and i need to have a button put a file into a folder, i know how the button works i already have it doing some other stuff. i just don't know the code to copy and past it to a folder.
When I add a new, empty form to my VB.NET VS9 project, the linenherits System.Windows.Forms.Formis missing.What am I doing wrong here?I thought it would be added automatically.I experienced that some thing get weird if this line is not there (Form_Load is not firing, I think).
Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs Public Message As String

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.
