I'm trying to convert the following C# code to VB. The reults from online conversion pages I have tried doesn't make sense to me and VS2010 marks them as flawed. My limited C# knowledge about events isn't enough to solve this one.

a user will enter a number, n, which ranges from 1 to 30. they will also enter a "P" or an "S" (sum or product). depending on which was selected, it will calculate the sum or product of the numbers from 1 to n.i'm having a conversion error on line 5 stating "Conversion from string "S" to type 'Double' is not valid."

View 2 RepliesI'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
Here's 2 questions that I hope someone can help me on. This is in VB.net. I keep on getting this error 'java.io.bufferedInputstream.count is not accessible in this context because it is 'Protected Friend'. Does anyone know how to fix this error?
The other errors i get are "Overload resolution failed because no accessible 'Val' accepts this number of arguments". I have listed below the code that I have coverted from Java. Where is my mistake?'the underlined areas are where it is giving me errors.

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

Here is code.
Dim Locate As String = Application.StartupPath & "\Games\"

Here's my problem i am trying to extract data from a forum
Now what i want is to remove a specific word from only a specific line
So here's a example
[quote=randombla13] I am the king of the world bla bla
[img]http//google.com/img.jpg[img]
[quote]This line should not be removed[quote]
[quote]
Now as you can see these are the codes you may have seen in many forums
Now want i want .Net to do is filter the the content in a textbox
And remove only the lines marked with red "[quote=randombla13]" from the first line
And the Extra "[quote]" from the end line
As you can see in the example the content has two "Quotes" so i jest want to remove only one from the first line and last line of the content
And note "[quote=randombla13]" the length after the = is Unknown it maybe of 6 characters or less or more
I was wondering how I would replace a specific character at a specific position.[code]...
View 7 RepliesStrange story... I downloaded VMWare but it has since advised of an available update. I downloaded the update and when I click to install it, a window comes up with VB Code from a project I created a while back in a completely separate folder from this install file. I then tried downloading the trial of VMWare Workstation and when running the installer it shows the same thing. I don't know of anyway to contact VMWare support since I don't pay for any services or products and all there is available is a FAQ type section. Of course this problem would not be in there, nor can I find any such related issue online. his is VMWare specific or perhaps the type of install specific. I have no other issues with any other app installations other than with VMWare installations.

View 5 Repliespublic class FloatToolStrip :ToolStrip { private Form floatForm; public Form FloatForm { get { return floatForm; }} c# is case sensitive so floatForm and FloatForm are different.
vb.net is case insensitive so when the inline compiler sees FloatForm, it says it has already been declared.
how do I convert the blue code into vb.net?
convert this code (Structure and its members) which is in VC++ to VB.NET.
#define GBIF_IP_MAC_NAME_CHAR_ARRAY_LENGTH 16
#define GBIF_STRING_DATATYPE unsigned char
typedef struct
{GBIF_STRING_DATATYPEucMacAddress[GBIF_IP_MAC_NAME_CHAR_ARRAY_LENGTH];// unsigned since the adress components can be higher than 128

I am getting ready to release a .NET 2003 application, and this application has a file type associated with it.During the installation I register the extension to be associated with my application, and everything is working fine.My question has to do with the icons. I want a specific icon for the exe, and also a specific icon for the files associated with my app.i want to have both icons in the exe file.I guess my question would be, how do i embed 2 different icons into an exe, so that if you selected that exe as an icon source, windows would see the different icons in it (as seperate icons)I know I can embed them as a resource, but windows only sees the main icon.To give you an example, of what I am trying to do, winamp, the mp3 player program, has several icons in its exe (see picture)(the visual studio IDE exe - devenv.exe - also has more than 1 icon in it)

I'm currently working for a client who owns a custom developed ASP/VB6/SQL2k5 3-tiered web application... The application has been developed over the course of 10 years by several different companies... I have a team who is in the process of rewriting components of this application over to a ASP.NET/C# applications, leaving the structure of the back end database in its current state (ie: no redesign of the database)... As you know, this is a very long tedious process when performed correctly... Our client is looking for a "wizard" type conversion tool or process instead of the redesign of the web UI and business objects... Several people on my team (including my architect and I) continue to tell our client this is not possible, that a full rewrite of the application is required... Can someone just validate my thoughts on this? Here are some of the technical specifications of the legacy application:
· VB COM objects are heavily reliant upon ADOR recordsets
· ~150k lines of VB code spread across 6 COM objects
