I am new to VB.NET, Now i'm working with Events in VB.NET, I have two event methods, Mouse Click and Mouse Down for a single button in a form, I have displyed a message in each of these methods but only mouse down event is triggered. Why Mouse Click is not triggered? Similiarly I Did the same for Mouse Enter and Mouse Move for a particular button, in this case both the events are triggered.
My program has two forms which get data from the same data source. After binding controls to tables and fields on both forms, I noticed each form has it's own apparently duplicate DataSet. Is it standard practice for each form to have its own DataSet even though they use the same ConnectionString and connect to the same database at the same time?
I've got to the stage where I want to make changes to my application so that all of my forms appear to the user as a single window.
I have a main Form with a menu bar which opens up three separate forms. Only one forms is visible at any time.
One way to do this, that I can think of, is to place all the controls from each of the "auxiliary" forms on a panel contained in the main form and then show and hide the panels, when needed. I can envisage this being a big headache though.
Another way would be to give each form a menu bar and make it look like the main form so that the user would not know the difference (with a bit of luck).
I just wonder if there are better ways to do this. Maybe if I could incorporate one form into another form?
i wants to load many pages in same form which each of the pages contains different messages.example....if i press more in the page no1(form 1) it should load the page no2 at the same form(form 1)...
I've written an application with about 30 forms and am almost ready to publish, my biggest concern though is that i'm not sure if its a normal thing to do having all these forms and hiding, disposing and showing forms throughout the use of the application.I've toyed with the idea of converting to a MDI Child / Parent interface as well as having one form with lots of subcontainers that are hidden and then hiding / showing them as the navigational buttons are shown.Ive worked on this application for about 8 months now, but would be happy to rewrite the interface and appearance of it if i know that it is not generally an acceptable practice having forms flashing open and closed while navigating through the application.
I'm new to vb.net and I have what probably is a simple question, but one that I am stuck on. I'm trying to add a single item to a ca combo box at run time. For example, a user selects a category from the first drop down box at run time, say "Admin", I want to add a single item to the combo box below it: Not applicable.
Most of the apps I write have a base / home form and a few other forms (three of four typically) which pop up in response to controls clicked by the user. I'd like to be able to set some properties to be the same for all the forms in an app; particularly properties like BackColor and FormBorderStyle. Yes, I can manually set the individual properties for each form in the VB IDE, but I'd prefer to be able to have one line of code in the base / home form for each property along with one line for each dependent form which says something to the effect of "use the same property value as the base / home form has". Overall, my objective would be to have one single line of code in the app which, when changed, would apply the changed property to all the forms. For example, a single line which I can change to take the BackColor from Apple to Orange for all the forms ...

I have a Search form where the user can click a Button that opens up a rtb with every single word (12,800+) used in the King James Bible. Every word is Capitalized ("Thankful, Grateful", etc), so in my code, the user selects a word, then right-clicks and sends the word to the TextBoxSearch in lowercase. Now, if the RTBDisplay (where all search results go) is empty, then a msgbox pops up asking if the user would like to re-search the same word in Uppercase. If they click OK then the word in the TextBoxSearch (lets says: "thankful") is supposed to become "Thankful". But instead, the TextBoxSearch goes blank. I have tried many variations of code, and here is my latest (doesn't work):
If Me.RichTextBoxSearch.Text = "" Then MsgBox("Would you like to search the same word but in Uppercase?", CType(1, MsgBoxStyle), "Re-Search?") If CBool(MsgBoxResult.Ok) Then[code]....

I have been working on a project which is used by a company's sale team, to combine all the wanted input data in one place allowing the sales team to show customers, where switching to them could save them money.
Basically what i want is a program which can save single records, which can hold data added in other text boxes, or indeed take the data from the list view boxes which is the intended output. I want to be able to save that data, then be able to Open it up again at a later date, and even modify it.
enabled me to save the three ways to identify a single record, the index number, company name and the date it was added. However I now need a way to save the data entered in my other forms to these single records.

In my application, the user clicks a single button and the program displays each network adapter description into a message box and then gets all the ip info for the workstation and places it into a text file and opens that text for reading. What I would really like for it to do would be to display all the network adapters into a single messagebox instead of messagebox for every adapter like it is currently doing. Here is the code I have on that button. Let me know if anyone needs more info or has any questions:
