I am the beginner to .net framework itself.I am too confused whether to use asp.net using vb or just visual basic is enough?As I am just thinking over this topic.I feel this is not a website so not to go for asp.net.I thought to do it in
As the beginner I want to know Is it necessary to add MDI parent for Library management System?
Can this be done without MDI Parent too?
And also is it necessary to add the below code for mdi parent of every project? Private Sub ShowNewForm(ByVal sender As Object, ByVal e As EventArgs) ' Create a new instance of the child form.
I have read syedwaqasali95's thread but found it rater confusing so thought I would post my query separately I am trying to build a library system for a local blind person's charity using Visual Basic. Their current system of recording is an Excell Spreadsheet that was created for them by someone else. What they have asked for is something more User Friendly.I thought about using Access first, but I wanted to hide the Data where it couldn't be modified by accident, and I wanted to make it as user friendly as possible so I opted for a VB WindowsFormApplication that will have a simple user interface albeit having to get more complicated under the hood.The library has two types of items that they lend, Audio Books, and Music CD's. Also there will need to be a record of the members creating three tables for my database.I should state that the library has a laidback lending approach whereby it is less worried about how long you borrow a book or CD, rather it just wants to keep a record of the location of said items.
I need help/pointing in the right direction with the following things 1) I want to prevent any ability to directly edit the datagridview data instead I want the user to highlight the entry in the datagridview, and then click an edit button which will open a form containing the record to be edited.
2) I want to be able to call information from the borrowers database, and to be able to apply it to the books data, so that the user can see who has what book at any given time.
e.g. the user highlights a record in datagridview and clicks the "Lend" button, this pops out a form allowing the user to search/choose from the list of members, once a member has been selected the save button (or confirm lend) would add the member info to the book table and close the form
3) I have a large amount of data (1500 records) in the original excel document, I would like to import these (once the database is ready to be compiled) so that they don't have to be re-input.
I have developed an app containing a form in vb.net with MSAccess as its back end . I have deployed it using Install shield . I have packaged Access 203 redistributable image with it . Every thing works fine till installation. When i launch the app , enter a value in the text box and search for it in the database and display it , I get the following error ,
I've created a custom class that I've grown rather dependent on in my coding. I've encapsulated it as it's own "Solution" and use a reference to the class module within the solution on most of my new projects, and that all works fine. It seems slightly clunky to me that my encapsulated class module is packaged with solution-related directories and so forth. For me, this seems to make management and maintenance of these little class modules difficult (renaming them for instance). So now, a few questions:
When you recognize you have a useful class embedded within a solution: 1) What's your method for encapsulation? (is there a template you like?) 2) How do you organize/arrange your code libraries? 3) When, if ever, might you consider using that "Code Snippets Manager" thing in the IDE?
I'm struggling a bit trying to understanding how Visual Studio wraps-up everything in what appears to be a "Solution" umbrella. There doesn't seem to be a lot of write-ups on how to go about organizing your code libraries to work well within this Solution/Project Visual Studio framework.
I've just finished installing VS2010 on my computer. I have a project I built in 2003 that I'm trying to open in 2010. It went through the conversion process and generated this error: System.SystemException - The type library importer encountered an error during type verification. Try importing without class members. : System.MissingMethodException - Method not found: 'Void
I am trying to manipulate files as part of a Document Management application that stores documents in a location on a Network Drives. But the My.Computer.FileSystem.Drives collection does not contain the Network Drives mapped on my machine. I have about half-a-dozen of these, but none of them seem to show up in the Drives collection and thus are not visible to the other FileSystem functionality I need to use for file management.
how to make sure the Drives collection contains all my drives? I am running VS2010 Premium edition on Windows 7 64-bit on a 64-bit Dell machine.
I am using VB Express 2008, and I'm experimenting with querying WMI. I have tried the code samples from MSDN, but they do not compile. Here is an example of code that my IDE doesn't like:
Imports System Imports System.Management Public Class Query_SelectQuery Public Overloads Shared Function _
[code]....
In this case, SelectQuery and ManagementObjectSearcher are underlined with squiggly blue, and it doesn't know what these are. What am I missing here? Please help, because I'd love to be able to write console apps that query WMI.
I'm trying to write some code that can read events from another computer's event log. I haven't used WMI or System.Management all that much before this, and despite all the examples I've found on the web (there's a lot), I cannot authenticate to another machine.
No matter how I tweak the code, I always receive a System.UnauthorizedAccessException in System.Management.dll. (The message is "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))".) I have tried connecting to two different Vista machines on the network using their local user account information.[code]...
I want to learn by resolving a problem i have been having with my small car hire business.
I want to develop a system which will enable me manage the business efficiently, the solution should be able accessible to more than 1 users, on my LAN and i would also like to have a web reservation system.
How easy/difficult is this when using VB.Net and what things must i do at the onset to achieve my goal.
I've been assigned to do some report analysis in a management information system.My question is, do you think it's a efficient way to gather datas from SQL, with the use of basic syntax and have them manipulated through my code in VB.NET?(I'm more skilled with this kind of execution, but it takes a lot of data calling from the database)Or should I just do the advance way of inner jointing or more likely a stored procedure?
I ran accross this piece of code that uses the System.Management to get the free space on a drive for ONLY logical drives on Hard disks drives. It does this by check the Mediatype. Anybody know where I can find a listing of the Mediatype values? I would like to modify this to get free space only from USB flash drives.
I have read a ton of stuff about this but not getting it, noob error I am sure
Type 'System.Management.ManagementObject' is not defined. Type 'System.Management.ManagementObjectCollection' is not defined. Type 'System.Management.ManagementClass' is not defined.
I'm looking at creating an asset management system for all our electrical equipment, the equipment already have security labels with barcodes on them. What I am wanting is to be able to do is create a form where i can state some general information about the piece of equipment and then scan a barcode to register the equipments security number. so that if an employee needs to use that piece of equipment off site then I can just scan the barcode and register that the employee has taken the equipment.
My understanding is that the barcode reader is generally plug and play and acts as an input device? So what I would need to do is find a way to identify which input device is used, and if it is the reader find a way to assign a labels text to the value that has been read, rather that insert it into a textbox? I also want to display the actual barcode itself above the label, so I assume I would need to re-generate the barcode as an image and then display the image?
Basically I am trying to create a child management system for a nurse using vb.net and SQL as my backend dbThe application consists of a number of differen forms. Two of these forms are called "frmSearchInfo" and "frmChildDetails".
frmSearchInfo consists of: - three textboxes "SFirstName" "SLastName" and "SDOB" - one button "BtnSend"
[code].....
When users enter details on form "frmSearchInfo" I want it to be able to search records in the database and return the same first name, second name and DOB as well as the ID, phone, addressline1, addressline2, county. I also want the datagrid to show dates of appointments for the children.The records needed are stored in the Child Table.
I have some software that does the following code to try to loop through the software (MSI's) that are installed on a machine. Originally it was passing in a package name as a parameter, but I've simplified my code to make it easier to follow. It was working before, I can't figure out why it's not now. Here's an example snippet with a package that doesn't exist:
I need to read the value of one subkey located under a list of 17,000 keys in windows registry. I have no problem doing it locally but cannot get the system.management name space to do the same remotely. I know MSDN documents the system.management name space but much more knowledge is assumed than in other areas I have used. Assume no problems with connection and authentication.[code]....
I have created a windows Service which invokes executables on remote machines, waits for it to complete and then proceeds to the next machine on the network.
The Account type for the windows Service is "Network Service". For monitoring if the process is completed on the remote machine, I am using ManagementEventWatcher class. I get the following error when I start the Management event watcher object.
I would make an unattended recovery disk for my Dell laptop using Windows PE 2.0 and, so I am in need of a program which analyzes the first disk on the system in order to get all partitions. The program should check: - if there is an OEM partition (hidden); - the number of logical partitions; - the number of primary partitions. Then, if there is only a primary partition, the program should delete it and create two primary partition...Is it possible?
I am looking for an open source .net DMS. I know in the post below there are some c++ but am not familiar with it so that would be much help.I found this post but is was asked back in 2009 so there might have been some progress or additions to this? Open Source Document Management System in .net? The reason for open source is that I would like to be able to integrate it into something else later on. I would also need it to be a desktop based system and not web based.
I am able to query/read the "Application" event log using System.Management classes in VB.net 2005 (win xp)But I have problem reading the "Message" / "description" of my custom event log.I am getting a System.NullReferenceException{"Object reference not set to an instance of an object."} while reading the "Message" / "Description of the event log while it is reading the others properties.Also when I use System.Diagnostics.EventLog and read all the Events on by one I am able to read the message/description of my custom event log. Why is that the System.Management classes can't read the my custom event log messages while the System.Diagnostics.EventLog classes can read them.The reason I want to use System.Management classes is bcoz I can query my custom event log where as with System.Diagnostics.EventLog classes I have to read the whole event log.
