I was hoping that the various controls for WinForms in VB.Net 2008 would have a property such as OldValue and NewValue that I could pull from the Change property.
I'm wanting to write a generic code that will save the OldValue, NewValue, name of field and name of table, and date of change directly to a simple Audit table.
Items aren't changed often, but we need to be able to trace the history of changes to certain fields. I've got the code written for saving to the table, but I'm not finding anything that will show me the two values I need.
I get the NewValue from the changed property but how can I locate the OldValue for date/time pickers, text boxes, check boxes are the main items on the forms.
How To Create Audit Trail Of Record Changes In A Form In Vb Net?I get the NewValue from the changed property but how can I locate the OldValue for date/time pickers, text boxes, check boxes are the main items on the forms.
I would like to perform an audit as part of a unit test that uses reflection to verify some assumptions, the basic-psuedo code for this would be as follows:
Are there any examples of PC Audit software or tutorials/code? While I found 80% of my questions on this forum, like how to retrieve ram info, how to retrieve hard drive space, etc..
above the sql statment, I want to use in my login form. When a user loging in software then it will set up all above option in sql end but how to set in code
I've got an application that takes the files in a folder structure and publishes them to another location. Currently it goes through every folder/file and compares the dates in the source and destination. If the file doesn't exist in the destination, or is older, then it copies it across from the source. It's obviously foil proof, but not as fast as it could be.
Ideally, I'd like to create an audit (or audits) saying what the current state of play is in the destination and compare the source folders/files against that instead.
This of course assumes the destination isn't messed around with manually, but I think that's a fair limitation.
So has anyone got any suggestions for how this audit could work? ie: How I could store data/values, such that on the next run when I look down the source folder/files I could compare it to the audit and see 99% of the files are unchanged, so only send across the X new ones etc?
ps: I don't suppose there's a valid (in Windows) that can tell you the date any file in a folder was created/amended? ie: So rather than checking down 200 files to see their individual dates/times, if I could get a single folder level value saying the date of last update/create, if it hasn't changed since the last run, there's no work to do! There is GetLastWriteTime but this doesn't seem to get updated if you amend/update a file, rather than creating a new one!
I have a winform which allows people to edit data from a database, to simplify things assume there is a Customer table in database with 3 fields - Name, City, Country. Through winform(s) people can Add/Edit/Delete customers.For each of these actions we need to save:
What the field names are (Name,City,Country in this case)What the field values were before they were modified What the field values are after they are modified.If the action is Add or Delete then 2 and 3 will be the same.I have already implemented this using XMLSerialisation (but not using any of the design patterns) and my XML output looks like this.
The solution can handle different areas of the system with different number of fields (i.e the same thing works when you are modifying Products for instance).is there a well defined design pattern to deal with this kind of behavior?
Using a timer, am making a rectangle platform move from left to right. The problem is that it leaves a trail of itself and I believe this is down to refreshing or something. here is the timer code if your interested:
If shaperet = False Then Timer2.Start() platform.Left -= 4
I'm trying to create a 'trial version' for a software of mine, currently it is pay-only. Basically the most efficient way I can think of is to simply change the startup form of the trial version after 15 days. The new startup form will simply be a request to register.
-How can I change the startup form after 15 days? -How can I ensure that this cannot be changed afterwards (so it isn't easily pirated).
I've run into another road block while programming my game. The problem is that when a player types North in room "Crash Site" They get the description of traveling to the next room "In Trail" as well as the description of traveling to the next room after that, "Deeper In Trail" before having to type north again. I've looked over the code several times, but can't find the problem....the conditions seem to be fine, but I'm guessing that's where the problem is..
Code: ElseIf LCase$(txtInput.Text) = "go north" And Room = "Crash Site" Then Room = "In Trail"
This is my first time so please be gentle. I hope this is in the correct place.Basically I want create a reg key that will effectively add a site to the trusted zone of IE.I have got so far and can create the key but I want it to create a REG_DWORD and not a REG_SZ. My code is:
[Code]...
I only have a very basic knowledge of VB but am trying. Basically I want to run a script that will add this website to the trusted site of users. We will have hundreds who need this and want to create a script to speed it along. I will be adding other things to the script as time goes on but this is the first step.
I'm looking to create an API for a website I have built. The API will be built in ASP.Net - probably using VB and will need to be consumed by multiple platforms including PHP. I've read a bit about REST vs. SOAP APIs and am confused about which route I should go. I also need some examples and frameworks I can use to get started.
I am trying to learn how to create a DLL in C (using Visual C++ 2010) for use in Visual Basic (2008 Express). I am a novice programmer, so please bear with me. My objective is to learn how to do starting with a very simple function, and I foundC++.html This examples presented in that tutorial are for Visual C++ 6 and VB6. I know there are differences between VB6 and VB2008, so maybe this is why I am running into problems following this example. In Visual C++, I created the DLL as a Win32 project. The function is simply summing two integers. I put the function "sum" in the source file "dllmain.cpp."
Is there any C# .NET ORM that can create databases? It should be capable of creating MS + MySQL + PostGre + Oracle databases at least.And I don't mean tables or schemas, I mean the database only.I use nHibernate, but it can only create tables and schemas, and query/insert but not creating the database itself.
I am wanting to build my own version of MSN complete with server etc, I was wondering if anyone had any basic tutorials etc? I dont plan on making it open to the public and it will be purely for learning, just looking for something to do now that I have made my own version of paint, advanced web browser, media players etc... just looking for my next learning curve.
I'm building a simple udp lan chat application in vb.net and I'm wondering how I should split my packets. Each sent packet should have like an id, a username and ip address from where it's coming and maybe also a command part for like join or leave to update my userlist and a text message. I'd like to know what is the easiest way to put all this in a simple packet then easily split and access different parts from it when it's received. thanks.I'm using UDP since this is only in lan so i'm broadcasting to *.*.*.255
What I want to know is what would be the most easy and powerful way to format my packets so they include a username , an id, a command and a text message, then the user receiving it decrypt it to show only the message written by which user or if it's a command like join or leave to show the appropriate message of joining and add the user to the list for exemple.
I have a vb.net web app, and I need to give my users the facility to download a ms-word .doc file. This file needs to be created dynamically, and should contain some bold text and a table.
I've come across this code, which builds a .doc file, and lets you download it:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim strFileName As String = "GenerateDocument" + ".doc"
[Code]....
...but I don't know how to make the text bold, or create a table. I'm sure there's a better way.
I'd like some advice on building in known errors. Let's say I have a Windows form that needs to set the source path of an image in an object. It must be:
notepad file means that is used for .java file and .txt files.so this files should be converted into .exe file using the vb.net environment.so, if its required software is not installed in any pc, that file will be opened without its installation s/w....I know this is used without the code.. creating a .exe file i hav to write a code..
I want to create a big list box that has lots of default values in many lines so they can then be edited later.Right now I have in my initializer:
Dim counter As Integer = 0 For counter = 0 To counter = totalNumber listBoxThingy.Items(counter) = ("DEFAULT DETAILS TO BE COMPLETED") Next
with my list box called listBoxThingy and totalNumber a previously defined constant of how many items I want in my list box.yet when I try to run the code I always just end up with the first list value containing the text.Even if I put a counter=counter+1 it still only gives me the one completed value of my list box?
