Return DLGC_WANTARROWS To The Message WM_GETDLGCODE?
Nov 3, 2009I do have a control that inherits from UserControl.As you should know, I dont receive the WM_KEYDOWN message for the VK_LEFT, VK_RIGHT, VK_UP and VK_DOWN (Arrow keys). They are processed by window Proc as being a TAB key and not dispatch to the WinProc of the control. Instead, The control receive the message WM_GETDLGCODE.
In C, to get them, I use " return DLGC_WANTARROWS; " when I receive this message to get these virtual key and prevent Window Proc to move the focus to another control.However, VB does not let me used "Return" from Winproc, So, how can I get these arrow keys to be dispatch to the control.

View 1 RepliesReturn An Object As The Return Value Through A RealProxy Transparent Proxy?
Oct 7, 2010I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works.

Query A Database And Return The Results?
Jul 22, 2011I would like to create a vb form with a combo box (with song title), a text box (for song lyrics), and a button (to submit or refresh). It is linked with an access database. The combo box is populated with the songTitle field in the db (this part works fine). The text box is populated with the lyrics that go to that song The first updates fine but I can not figure out how to run a query to pass to the text box's text property. I want the user to be able to select a song from the combo box, click the button, and have the text box populated with the new song's lyrics.
Any suggestions on how to accomplish this, or a good place for a tutorial that explains the necessary elements for having vb query a database and return the results?

Xml - Can't Get XPath Query To Return The Right Nodeset?
Jun 2, 2011I've got an xml file that looks like this:
<Records>
<Record>
<table>[code].....
What I need is to select all the ROW nodes, across all records, so I'm using something like this:
rowiterator = Me.XMLDocument.CreateNavigator.Evaluate("//table/Row")
which is working, but it returns a NodeIterator that only contains the first Row node in the first record!? As far as I can tell, that's the proper syntax for an xpath expression of "return all Row nodes with a parent table name anywhere in the document".

Using A Web Browser To Send A Gmail Message And Have A Home Pc Return A Email In Response
Apr 6, 2012ok here is my problem, im making a little app for school since our school blocks pretty much everything so here is my plan a student makes 2 gmail accounts one for school one at home.
in the program at school (client) they put a site request into a textbox and they hit send, the request is then sent to the home pc gmail account and another app on the other side downloads the full site that they have requested and then sends them an email back with an attachment of the complete website, it is then opened in a browser and they have the site, simple idea and it would be easy except.
my school blocks the smtp protocols in vb, even outlook cant use gmail accounts only the schools registered email, however, you can access gmail on the internet without any blockages and you can send and recieve on the gmail website.so how can i use a webbrowser control to log the user into there gmail account through a custom gui, and send a string like www.facebook.com to the home pc gmail account, and then use the web browser controll on the students laptop to recieve the response email through a web browser, is there some kind of gmail api i can use?

Return Result Of A TSQL Query In Program?
May 14, 2011I have a VB.Net program that will basically make a query to a remote MS-SQL DB using TSQL, return two columns (normally 4 rows/records), 1 is a datetime and 1 is a double. I will then need to return the average of the doubles (which is easy in VB.NET).
As I will need to run this query perhaps 1000 times an hour (programmatically with different input parameters for the query), I am looking for the most efficient way to code this up so that it will take the shortest time to run. I tried SQLDataAdapter and then using dataAdapter.Fill and sometimes it returns an empty set although the raw select query has values returned.

Sql Query Doesn't Return Any Results On Datagrid
Jul 7, 2010I'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...
