Creating A Tool Or Utility Or 'helper App' For A Project?
Nov 23, 2009
It seems that in C#, a solution can contain multiple projects, which, I guess, would compile into separate but somehow related programs. It seems that this functionality is missing in VB, even though VB uses solution files as well.How would someone go about creating a tool or utility or "helper app" for a project? For example, a command line version of the program, which is a separate executable, but obviously would be distributed as part of the main program? Maybe I want to integrate a feature into windows where the user can right click on a certain file and choose "convert" from the context menu, where "convert" would open the helper app, which would read the file and save an updated copy of the file (converting from one file format to another and saving the result) without the user needing to wait for the main program to load, wait for the interface to be configured, then wait for the file conversion. The helper app would not need to display an interface to the user - just convert and save the file.
What I need to do is be able to enumerate pretty much all hWnds and locate any TextBox (outside of my program) and get information about it (eg: Name if any, text in it, etc).
I am creating a password managment tool and for the storage I will be using a text file, I want to encrypt so I decided I will use the Rijndael cypher. I have found source code which does this to a file:
http:www.codeproje...ncryptFile.aspx. It is well explained but I am but still struggling to understand parts as I never looked at cryptography at all before.
Private Function CreateKey(ByVal strPassword As String) As Byte() 'Convert strPassword to an array and store in chrData. Dim chrData() As Char = strPassword.ToCharArray 'Use intLength to get strPassword size.
[Code]...
This assigns all of bytekey with half of the hash from byteresult. Am I correct? If not why not just use SHA256 instead of SHA512 as you are only using half of the hash. If somebody could explain this to me this would be great. Already confused and this is just creating the key, then the IV needs to be created(not sure what an Initialization vector does) then the encrypt/decrypt function. I think I will struggle understanding this but I am going to try.
i am creating a temperature conversion tool with vb 2010. i am trying to use radio buttons to choose the type of temperature that i am converting to and from.

I haven't been doing a programming for awhile now. But, I was a VB programmer before. I will be creating a tool to log issues encountered by the users of our system. It will be a web based. I'm planning to create it in VB.Net. Any resources that you could share is greatly appreciated. I'm looking for a ready program that I could start with to speed up my programming.
Is there any tool I can use to create a report from a pipe-delimited file? This report will need to have multiple fonts on the same line and be "programmable". I need to be able to loop through a section to output detail data to the report, keeping track of how many records are output.
I recently added a class I created with a tool to my Visual Studio 2010 project but I can't call it in my codebehind file. I was told I need to check the namespace. How do I check and control a classes's namespace?
I am creating a small admin reporting tool that gathers certain information on some PCs. Unfortuantly the user that is running the tool doesnt have access and I cant give access to those particular machines. What I have done is created a user on these machines that can get this information.I would like to then have the reporting tool run certain parts of the code as this user so the information can be obtained, without any intervention from the user running the tool. Can I hardcode this user into the code so that it runs the code as the user?
i have created a project in asp.net.now i want to implement asp.net administration tool in my project for user management.The tool works fine in a website ,but in a project it does not work.
I am creating a user tool for a game I am playing (NOT a hacking tool, it simply shows information about my own character). I have a template of what I need to do with the data I recieve, here is the code, it is coded in PHP
Ok, I understand PHP a bit (As you know one programming language you can understand just about any) and this is what I have created from this
Dim Style As Decimal Dim Rank, RRank As Decimal Dim Gender, RGender As Decimal Dim Aura, RAura As Decimal
[CODE]...
As you can see, it is receiving a single piece of data from a remote SQL server, I then need to run this data through the above calculations (Seen in the PHP file) although the answers I'm getting are incorrect.
Here are some simple instructions I got in what goes on between values:
How do I modify or create my own Html.ActionLink helper to accept and handle the first parameter (linkText) passed in as an empty string / nothing?Details: I currently have a strongly typed view that's passed a model which contains search results. My view loops through each item in the model and attempts to display a link to a contact with the following code:
@Html.ActionLink(currentItem.ContactName, "contact", "details", New With { .id = currentItem.ContactID }, Nothing)
Normally this would work just fine, but not every item in my search result has a ContactName. The Html.ActionLink helper errors when this first parameter is empty. In case it helps, here's the model property for ContactName (which is generated from a template due to Database First, so I don't believe it can be modified):
Public Property ContactName As String
I'd like to have a helper function that simply returns nothing if the ContactName is an empty string / nothing.I'm guessing I need to extend this helper, and I've struggled to find any good, up-to-date resources in VB.net for extending helper functions. Other approaches are more than welcome if they're considered best practice. I'm working in VB.net, MVC3, and Razor in the ASP.net 4.0 framework.
Lets say I wanna write a string "Hello World" into a MemoryStream and read this string to MessageBox.Show() without using Helper objects such as BinaryWriter and BinaryReader and StreamWriter and StreamReader etc.
how to accomplish this with low-level functions of MemoryStream stream object.
im trying to create a .dll called PDTKey.dll (for example) that will hold all of my applications Product Keys..and when the user inserts a Product key into the main application..it searchs in PDTKey.dll to see if the Poduct key specified is there..
I have a pretty large project built in vb.net under VS 2008. This project is heavy using SQL.
There is one part of the project, that I need to make a smaller project. So I am taking 6 forms out of 23 and adding them into this new project. Instead of adding the data set, I built a new one. With a different name. But it's connect to the same database.
First of all, is this a good way to make a sub-project, or is there a better way.
Secondly, I am running into a problem where my table adapters are not members of dataset. I get this error in the design code. I know it's not a good idea to manually change this code.
create a COM dll in Visual Basic. [URL]I now want to use this dll in a C++ project. I used OLE/COM Viewer to create an .idl file as is described in the second half this tutorial.[URL]I compiled the .idl with the midl compiler and included the .h file that was created in my c++ project.Here is my Visual Basic Code
<ComClass(MyComClass.ClassId, MyComClass.InterfaceId, MyComClass.EventsId)> _ Public Class MyComClass #Region "COM GUIDs"
[code]....
I receive the following errors when I compile my c++ project
error LNK2001: unresolved external symbol _CLSID_MyComClass error LNK2001: unresolved external symbol IID_MyComClass
I've been assigned to start a new Logging Project from zero in VB.NET.The final exit of the main project is information organized in paragraphs like this:
[code]...
Every paragraph correspond to a database connection. Every connection is made with an entire diferent database.i need my logging project to save everything the user does, so the logging exit would be like the system exit but with exceptions and other important information like this: Paragraph's title 1 Paragraph's content 1.Paragraph's title 2 User wasn't able to see this information because an exception ocurred: System.WhateverException:couldn't connect to WCF.as you can see the exit is the same but i need to create a detail log because the information is delicate and the DBA needs to now wich user did what and what was the response of the system. Also i need it to be and independant project so i can re-use it in another projects. Seeing the final exit of both the main project and the logging project, what would you recommend me to use for logging in .NET?
i'm currently working on building a program that will take a MS Access database system produced by my company and create a VB.Net project with all the forms in it (obviously the code should be manually done, but to save time the forms and controls can be produced automatically).I have tried Googling and seem not to be able to find anything about this (which probably means I wasn't searching with the right keywords), I was wondering whether anyone knows any good resources on how to create the VB.Net project programmatically as I already know how to do all the access stuff.
I am building an error log in a VB project. Is there a way to extract: 1) the name of the sub that a sub routine fails on? 2) what line of code a sub routine fails on? 3) what other items can I extract that are meaningful?
I am working on a project that has some events already created and working. One of these events is called SelectedIndexChanged Event. I am using it for one of my Subs in my frmNewInspection Class, and I am trying to use it for a second Sub and it says that "Event SelectedIndexChanged Cannot Be Found".
The event is created here in a class called LabelComoBox Private Sub tctlInspection_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles tctlInspection.SelectedIndexChanged 'MsgBox("Index: " & tctlInspection.SelectedIndex.ToString) [Code] .....
So, I fired up my old laptop while my current app was running and tried to start a new project.
As soon as the form comes up, I see this instead of the normal windows form.
Code: at Microsoft.Win32.RegistryKey.Win32Error(Int32 errorCode, String str) at Microsoft.Win32.RegistryKey.GetValueNames() at Microsoft.VisualStudio.Shell.Design.WindowPaneProviderService.AppendWindowPanes(RegistryKey parentKey, ArrayList windowPanes)
i am trying to create a simple program in vb.net but i cant start because there are no items found.. no forms are found am i missing some libraries or i installed it the wrong way?
I'm trying to use the System.Windows.Forms.MonthCalendar control within a VSTO Excel workbook. I want the MonthCalendar to pop up when I click a button in the ribbon, but so far I can't get the control to display at all.
Private Sub DeliveryDateFromCalendarButton_Click(ByVal sender As System.Object, ByVal e As Microsoft.Office.Tools.Ribbon.RibbonControlEventArgs) Handles DeliveryDateFromCalendarButton.Click
Is there any performance hit (or other problem) to creating a lot of class and structure types for a project? I'm not talking about the number of objects existing in-memory during runtime; rather just defining a lot of object types during design time. I find myself making a lot of small classes and structures that are little more than simply packaging a few related variables together.
