I'm trying to connect a remote mysql database. I'm doing it from a vb.net 2005 application with a connector mysql.data.dll What's happening is, suppose if I try to connect thrice it connects twice and once throwing an exception that says A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. there's nothing wrong with the code, otherwise it would never have connected
View 4 RepliesI have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.

I am working on a Data Survey Project and first I have a few questions about the different types of databases, and second, I need help querying my tables that have relationships.
1. I need a database that is stand alone. It is just the back end for the program. Simply to hold all the data an employee gets while out on a job. So would I be better using access, or SQL Express? I have played with both, but I do not want a large redistribution to my user machines. When I compile and produce this app does the SQL Database still work without installing any SQL Technology? Or do they have to go in after they install my app, and install Express?
2.Overview: I suppose depending on the first question regarding the database, it might change this question a bit, but none the less...I have 4 tables( using Access at the moment) I will be generating Reports based on data in the database. I haven't gotten that far yet. *Project* is the table that holds all the details that pertain to the job and client. It has a "one-to-many" relationship to *Survey*. So for one customer there are going to be many Survey Records. *Project Type* also has a 1-to-many back to *Projects*. Parts is kind of an orphan, but is linked to the *Survey* table with a one to many. So there can be many parts for one survey. I wanted this table for a drop down box, so the user could just simply select what hardware he was using instead of typing all the names and parts.
So in VS 2008 using the Designers and related Query tools, how do I constrain the Survey Data to one Customer? I have one form that opens from a button that is "New Project" and then there are all the *project* fields listed, so the user fills out the info and hits accept and that opens a new form called "frmSurvey" I need to add some code to the accept button to check what type of project is selected from the frmNewProject and then run a select query based on that. How do I write query statements in the code section of the form, without using the Visual Database tools?
Ill stop here, and get these questions out of the way first. If I could just get a handle on how to use the data properly with different forms and different controls with my queries, that would be great.

I have a window form with a label. On the form I have a dataset, bindingsoure, and tableadaptor (all created by the IDE in response to binding the text property of the label) To fill the datatable, the IDE created this: Me.ClientsTableAdapter.Fill(Me.MyDataSet.Clients) Works fine. The bound field is a phone number, stored in the db as a 10 digit numeric string I need to format this with the standard ()-, and I have a function that will do just that. How can I apply the formatting so the phone number appears in the label properly?

I need to find a Windows forms Text edit which can handle MS Word documents correctly.That is documents with Images, textboxes etc (.doc, .docx).I have tried Devexpress Xtrarichedit and TXText Control but when you load a MS Word Document (.doc, .docx) the document does not appear as it does in MS Word.That is Textboxes overlapping images are misaligned or have no transparent background option, so the white background of the textbox hides part ot the image.Has anybody had experience with 3rd party Document .net editors which mamage MS Word Documents correctly?
View 3 RepliesI am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.
I've spent the best part of the week learning about TCP/IP and sockets but it's really draining my enthusiasm for my project. The basics are simple enough and the MSDN examples are fine and I can put together a simple server/client easily now, but once I start getting into asynchronous connections, threading and all the other stuff, I'm getting bogged down and frustrated. I've followed a dozen tutorials and examples now and they're all too confusing and half of them simply don't work.
I think what's most frustrating is that I really don't wish to become an expert on sockets or TCP, which seems to be the advice on most forum replies. I really want to be getting on with my project which has ground to a halt since I started looking into this. Yes, I know the world isn't always that simple.
So, what I'm looking for is a 3rd party app or some working code that will let me set up a server and multiple clients. All I really want them to be able to do is to send strings to each other, without blocking the application. Really, that's it, just the ability to pass strings back and forth between server and client, preferably in as simple a format as possible - e.g SendMessage(Client,String).

I have a third-party .dll file provided to me by the manufacturer. I have never worked with .dll files before, so I am wondering:
How can I add the file to my project?How can I utilize intellisense to use the methods in the dll?
I have a third party dll that contain a class, SampleClass1
Public Class SampleClass1
Public SomeValue As Double
Public Function Test() As Double

My intention is if the dll is found, use it. Else ignore it. However, if the dll is not found, the program throw an Invalid OperationException.
I am writing a small application that will display some info to my end user. I have another program that the end user will have open while running my appplication. What I am trying to do is have my application launch itself (and maintain positioning if other app location changes) and "tether" itself to the other application.Ideally the top left of my application would attach to the top right of the other application.I have tried for countless hours working with the GetWindowPos API but the values returned are either all zeros or it just doesn't work.I do a Try/Catch to see if the other app is running and I fetch the Handle of the process. This works fine. Then I try to get the positioning of this process and set my .Left property to the returned RECT's .Left property. no dice.This is Visual Basic 2005 ExpressOther application is a PuTTY window that is not a fullscreen app.
View 3 RepliesIs there any code for vb.net so i can zip and unzip file without any 3rd party programs e.g. (i know this is not right)
Using zip As ZipFile = New ZipFile
zip.AddDirectory(directory)
zip.Save(targetZip)
End Using
my program launches a 3rd party program with a few switches to update itself.Once these updates are complete I need to manually click save from the applications menu. This can be done via the keyboard (Alt Gr + M then Alt Gr + S)
The application will take several seconds to load at which point the application will open maximised and the save option will be enabled.

Does anyone know of a good 3rd party reference for Win32 API for .Net where VB.Net is the target language Most API references target C as the language of choice. Frankly, I hate C and all C like languages.
View 11 RepliesI'm using VB 2008 and I'm trying to add a xmlns="mynamespace" attribute to an XDocument's root element.The XML document is created by a 3rd party, and I have loaded it into a VB XDocument object. As it comes, it has no namespaces. I have been working on a local copy and I added in a namespace in a text editor, so that I can use the XMLToSchema in VB to enable intellisense etc, as per the instructions in the Beth Massi vids at MSDN. Now the rest of the code works I want to open the live documents again. Without the namespace, my XML literals don't resolve.I've tried unsuccessfully to add in the XMLNS property to the root tag using a few methods, and the nearest I got was the following three code samples.
Dim myNS As XNamespace = "urn:nbf:namespacename"
myXML.Element("nameofrootelement").Add(myNS)
^^^^ The namespace was added as the value of the root element, not as an attribute.
XML.Root.Add(New XAttribute("xmlns", "name"))
^^^^ Generated the error: Run-time exception thrown : System.Xml.XmlException - The prefix '' cannot be redefined from '' to 'name' within the same start element tag.
but
XML.Root.Add(New XAttribute("test", "name"))
^^^^ works correctly. Presumably it doesn't like me manually trying to set a reserved attribute? This namespacing seems way too over complex from some of the Googling I've done.I thought to .ToString it, then modify, then .Parse it also, but I wanted a better solution so that it would help me understand it a little better! I did try this though, and as you rightly point out, it affects all the descendants too, so thus it still breaks.
I will be working with multiple XML feeds all produced by different third parties, and I think for simplicity I will be leaving out the namespacing entirely!My own custom parsing function rewrites the third party feeds into one uniformed document, which then gets processed by another routine. I'll be able to add a ns to that intermediate piece of XML which will help when coding the secondary function.
I am working with dev ex controls and on a menu bar item there isnt a property for setting the button to Visible or not Not Visible. Can you add properties like this to pre made controls? If so how would you do it?

Working on a program that makes use of a third party API. That API can be found here:[URL]I'm a beginning/intermediate VB.Net developer, and have written other programs, but not using something like this. I suspect I'll need to create a Web.Request (Secure) object and 'POST' to the URL with a stream of XML text. That's the general idea, right? The actual URL is internal to our network and I have that information of course.
View 9 RepliesHow can integrate particular Third party tool with my vb.net application
View 2 RepliesI'm still new to most of this but I seem to be finding that while you can load the Microsoft Reference Libraries at no charge, I'm told they are the slowest method to use.I have tested Gembox and only read about others. Is it worth the effort to deploy these 3rd party platforms, even if I'm working with small data sets, for the moment at least? Speed is one thing but when you're talking about 2 seconds vs 0.2 seconds, it's not worth $900 per seat.
Are there other 3rd party references which are Open Source, or no cost, etc...I would like to hear what the rest of us are doing on this?
Do i need to add a reference to a third party control(DLL) before i can use it.When i go to project->add refernece ,i select the control but it didn't becomeavailable in toolbox to use it.Do i need to install that control?I just placed it inwindows/system32 dir.
