Mysql And Visual C++ 2010 Windows Form Application / CLI C++

Aug 18, 2011

Working on a project trying to use mysql and Visual Studio C++ 2010. I have an established connection to the database on a server using a connection string. My issue is I am not sure how to get the retrieved data displayed in dataGridView. Below is where I have my code for the button named Search. Right now all I am trying to do is get already inserted information out and displayed. Not sure if I am utilizing the dataGridView correctly or if there is another way. When I select bind to database I do not show any data sources even though in my server explorer window I show that I am connected. I have googled my eyes out and still havent found any information relating to a non console application. Here is some code that worked and returned a value of 1 to a textbox just stating that it had no errors in the execution. [code]

Visual Studio 2010, Outlook 2010 And Windows Application, Return Emails?

Jan 5, 2011

At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:

Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)

However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

Print A Windows Form In Visual Studio 2010?

May 3, 2010

Is it easier to print a VB.net windows form in Visual Studio 2010?

I have been struggling with this - the PrintForm utility in the Powerpack only prints the displayed portion of the current form.

I spent a lot of time creating a process which loops through each control on my form, converts to a bitmap, and drops it on the print document, only to finally discover that the RichTextBox control (which I used extensively) does not include a functional DrawToBitmap method.

I have already researched various ways of managing this, but if VS2010 will do it without jumping through the hoops then I'll spring for it like the sucker I am.

I can do this in Access and VB6, I believe, so I don't think this is an unreasonable expectation.

Unable To Clear The Contents Of A Text Box (Visual Studio 2010, .net Windows Application)?

Mar 18, 2011

What I have is on my form there are several text boxes. These text boxes are for user input and attached to each text box is a Private Sub txtBox1_KeyPress function. In that function I have some validation code to check that the user is inputing only what I want them to. And if it doesnt it will pop up a message box telling them so, then it is supposed to clear the text box so the user can try again. But no matter what I try, the text box does not clear it still keeps the last character typed (the invalid one).

Here is the code for one of the text boxes.

Private Sub txtLanIp_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLanIp.KeyPress
Dim strEmpty As String = ""
If Char.IsDigit(e.KeyChar) = True Or Char.IsPunctuation(e.KeyChar) = True Or Char.IsControl(e.KeyChar) = True Then
'do nothing

[code]....

The commented methods at the bottom are some of the other things ive tried to make this work. The txtLanIp.text.clear() is what ive tried from the beginning. I have also tried setting the text to "", I even created an empty string and set the .Text value to it but no matter what it wont remove that character. I have also tried various trim(), len(), Select() functions, most either give me an 'index out of range error', a 'length cannot be less than zero' error or a general ExceptionOutOfBounds error. I am just tearing my hair out as to why the simple way doesnt work, there is no logical reason why and it gives no error it just doesn't clear the box.

I have also tried moving the validation to a _LostFocus but e.KeyChar isnt a valid method or property for that declaration, which doesn't surprise me but I wanted to try everything.I dont see how it would matter in this case but I am running Windows XP Pro SP3, though I also see the same behavior in Windows 7 64 bit ultimate sp1 and windows 7 64 bit pro.

Visual Studio 2010 VB Windows Forms Application - Organization Of DLL Project References?

Mar 26, 2012

In my VS2010 VB project I have a lot of external references to DLLs, to the point that organization has become a major headache and I'm wondering if I am going about it the wrong way. My assembly references include common redistributables (SQL Server Compact 3.5 SP1, ReportViewer 2010 SP1, DataVisualization, as well as some useful 3rd party dlls from CodeProject and CodePlex.

Currently, I am copying each DLL into a 1st level folder (/dll_lib) under my named project folder (under the solution folder), and adding the reference from that path. However, I see that Visual Studio copies the DLLs to various other locations (/bin/debug or /bin/release) in my project when I build the project or solution, and some of the 3rd party DLLs come with instructions to copy them manually to /bin.

What is the "best practice" for where to put the DLLs? Can I just put all of them under /bin and let the build event copy to /bin/debug or /bin/release as required? Should I try to force a single reference path for the dlls in the project output?

VS 2010 - MySQL Connector As A Resource On My Application - Connect To My MySQL Server

Jun 21, 2012

What i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.

The code i am using is below

Imports MySql.Data.MySqlClient

Public Class Form1

Function UpdateRecord(ByVal query As String) As Integer

[CODE]...

How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7

Winforms - Load System.Drawing V4.0.0.0 On A Windows Form In Visual Studio 2010?

Mar 4, 2012

I've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.

I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?

VS 2010 : Change Application From Windows Form To System Service?

May 3, 2012

one of the apps that I wrote a couple months ago is getting to be rolled out to my production floor; one issue tho - It works great as a standard executable (you double-click, it starts and waits for data), however, I cannot get it to start as a system service.

I've already done a little bit of research for how to create a system service, but most of the information that I've come across is point to VC# or Visual Studio 2010 - I'm not finding much for VB 2010. Additionally, I'm only using VB 2010 Express and I'm pretty sure that I don't have the Windows Service application template's on my PC.

My application does have a "UI", but there isn't any user interaction; it starts and just sits minimized in the system tray polling a directory for the existence of a file - i.e. the windows form is not required.

Windows Media Player Not Working On Windows XP Using Visual Studio Application?

Aug 8, 2011

I have embedded the WMP control in my Visual Studio 2010 app which works on windows 7 (Framework 4.0), but installing the app on winXP, I get the following error:

System.IO.FileNotFoundException: Could not load file or assembly 'Interop.WMPLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
File name: 'Interop.WMPLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

[code]....

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].

I guess this is a reference issue, but I have added references to WMP libraries (axinterop.wmplib.dll and interop.wmplib.dll). The WMP works on the XP machine, but not when called from my application.I have searched the web now for 5 days and changed references, and reinstalled the media player on the XP machine, but nothing works.

Mysql DB In Windows Form Id Field Has Negative Number

Jun 18, 2012

I got a Mysql sql database for my project. The id field is set as auto increment, which seems to function correctly. But on the form in my text field and datagrid i see a negative number, while in the database its a postitive number. I do not really plan to use the id field right now, but when i do it might cause some problems.

Anybody know why it would show as a negative number on the form(textbox/gridview) and as a positive in the actual database?

Installing A Visual Basic .Net Application On Windows 7?

Oct 4, 2011

We are installing our application on windows 7. The application utlizes a Acces database. The application locates the database by looking in the registry under at HKEY_LOCAL_MACHINE / SOFTWARE / WOW6432NODE / COMPANY NAME / SOFTWARE NAME /STARTUP. When i install the application on windows 7 it places the a database where installshield directs it to and writes the path to the registry. However, somehow local copies of the database are showing up under the user profiles. (Example: c:/users/profilename/AppData/Local/VirtualStore/Program FIles (X86)/Company/SoftwareName/Data). We recently changed it to store the information in c:/ProgramData/Company/software however the same issue occurs and its creating local copies of the database and when the application runs it points to the local copy of the database. What we need is for all users to be pointed to and use the same database in ProgramData, is there something we are missing to accomplish this?

VS 2010 Developing A Chat Application Using Online Connection To A Mysql Database?

Mar 4, 2012

I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).

Dim MySQLCon as New MySQLConnection
Dim MySQLCom as New MySQLCom
Dim counter as Short
