View 4 RepliesCreating A Logon System To Check Users In SQL2008 Express?
Jun 21, 2010I am currently creating an application to track timekeeping (a clock in/out system) and I am trying to work out the best way to do this.
I have a Main Form which contains buttons to ;
- Log in
- Out for Break
- In from Break
- Log out
When a user presses the "log in" button the logon form appears, the user then enters their username and password. What happens next is where I would like the help.
Process is as follows:Click Logon Enter Username/Password Check Logon Form for errors (eg no password etc) Check User is in Database (using SQL query) If user is in DB and username and pass are ok then refer back to the main form to perform Stored Procedure for what the user wants to do (eg logon or or out for break etc). Set label on main form to show user as logged on My question is should I be using a public variable and calling the main form again or in the user logon form having 4 options and using an IF ELSE to select the appropriate Stored Procedure?

View 7 RepliesATM System - Check Card Number Matches Up To The Users PIN Number
Mar 13, 2009I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.

C# - Which Options Are Ther To Set Up Your 3-Tier System
Jul 29, 2010Which options are there to make your 3-Tier System.Client / Common / Server Now we work with the entityframework and agatha. But are there other options to make a good 3-Tier system?
The agatha framework, makes for us the request/response on the common site. On the server site the response will be filled in. But are there other framework to do all that work for you? Or should you do it without such framework. And call at the server site stored procedure? Or with LINQ? With the agatha we query the repository's with some LINQ queries.
But i am wonna know if there are other ways to do the communication. Maybe there are other and better ways to do it. I hope i get some usefull answer. Where i can read some new things.
Date / Time Represented By String Is Not Supported In Calendar System
Aug 9, 2011I have a application which gets info from an external feed where dates are in the format ddMMM. I'm trying to turn them into full date format so I was using DateTime.ParseExact. Which was correctly working out whether it should be 2011 or 2012 . But it is erroring when trying to parse 29FEB (which should be 29 Feb 2012. I can guess why its erroring. But if that correct behaviour is this documented and is there a better alternative? [code]

View 6 RepliesVS 2010 Options View Control - Child Options?
Aug 20, 2011I am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.
System.Web Missing For End Users?
Sep 11, 2011I have been getting a lot of crash reports sent from my application that describe System.Web not being found.
I was able to reproduce the problem, and at first it seems that it would be caused by not running .NET 4.0, however, my test machine is running Windows 7 SP1 with .NET 4.0,
How would I go about fixing this problem? Was System.Web deprecated?

View 1 RepliesBuffering Using Ftpwebrequest - Allows Users To Login To The System
Mar 15, 2011This will be my first post on this site, so I thought I would make it a doozy. I have an web application on our site at work that allows users to login to the system, and submit filings for dockets that our state agency governs. Without getting to involve with what that means, they basically upload mostly .pdf files, but there are others that are acceptable to upload as well. The current system that is being used, uses a simple FileUpload and saving it to a folder on the d: drive of the webserver. I ran into a problem that with anyone outside the building/network, the upload is extremely slow and seems to be limited files no larger than about 1.4MB. There have been a few cases where larger file have made it through, but those ar few and far between. I've tried a couple different 3rd party components, but seem to run into the same limits. So, I install the FTP server on the box with the IIS and am trying to go the FTP route using ftpwebrequest.
Below is what I have put together so far:
Imports System.Net
Imports System.IO
Partial Class _Default
[CODE]...
This seems to work as it is at the moment, but I know it has a long way to go for catch exeptions, speeding it up...
1.) The first problem I have run into is if you try to upload to large a file, you get Out of memory error. I'm needing to change the buffer so that it is buffering chunks instead of the entire file. I've googled over and over again and seem to find several good options in C#, but can't seem to convert them to VB. So, could some one give me some idea how to take what I have and change the buffering to use smaller chunks.
2.) I need to catch an empty UploadFile field.
3.) I will eventually be changing this so that it handle multiple file uploads like my current system uses. (Did I mention that I'm new to the ASP.NET and have been programming in .ASP)
4.) As you will notice from my list of acceptable file types, I might have a problem with some needing to be upload as Binary and some not. So I'm going to have to come up with a way to test and change the Requested.UseBinary = False as needed.
I'm sure that I'll find other items as I progress or the big bosses will find other things that they want to add, but for now.... I know that given enough time, I will get all of these items worked out.
By the way, we have a network adminstrator that leave a lot to be desired and most IIS and now FTP I'm having to learn, implement and configure. I'm wondering if there is anything else that could be causing these limits in file size. Since I've tried 4 completely different forms of uploads and they all seem to run into the same limits, I thought there might be something in a router, firewall, server configuration.... that I might need to look into as well.

Hypothetical Controls - Options Checked As Enabled In FrmConfig Effects - Controls (like Buttons/menu Options) Are Enabled In FrmMain
Nov 26, 2010As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
