I'm trying to create an app in Visual Basic that will allow a user to input an address, state, zip, some radio buttons and other data that will then add information into a json file.
The JSON text is set up like this:
{"ChapterId":1,
"ChapterName":"Batesville",
"Region":1,
"Field1":"TestField1aData",
"Field2":"TestField2aData",
"Field3":"TestField3aData",
"Address":"72501",
"Latitude":35.775765,
"Longitude":-91.641083,
"ChapterType":"Active"},
The current Visual basic app is divided into two forms. The first form shows all "chapter" names which can then be clicked on and edited or create a new "chapter" which will then open a chapter editor. One thing I'm having trouble with is opening a current JSON file and formatting it to show up in the txtboxes I have set up for editing. Also, I want the chapter names to show up in a collection. When the user highlights a collection in a combobox and clicks a button it will open a window (having trouble with that too).
So the Visual Basic program opens up the JSON file (unable to get that to open)
Imports "Chapter Name" into a collection.
When a user clicks on a item in the combobox and then presses add new chapter or edit chapter it is then able to edit said JSON file.
IF ADDING NEW CHAPTER
The text will be able to create a new "chaptername" and add a new region address state as seen in the JSON script example. When the user clicks the update button, the new JSON text is added to the original JSON file.
IF EDITING A NEW CHAPTER
The text boxes show the original data from the selected chapter and will then be able to update that original "chapter" section.
OPTION TO REMOVE CHAPTERS
How to remove one of those sections of code within the visual basic .exe file
I'm doing this for a charitable organization (I know it seems like I'm asking for a lot of info, but I have to get this done within 30 hours and I'm pretty new to visual basic)
Thanks for your help.
Use Json.net or Json serialization. Have a look at MSDN article - An Introduction to JavaScript Object Notation (JSON) in JavaScript and .NET

This is my first application using VB.NET.
I am trying to add new windows form to my application. I followed the tutorials too but can't add the new form .
I am trying to add new form by right clicking in my project -> add -> Form (Windows Form). But this form does not show designer.vb code. I do not know what am I doing wrong. I just want to create a new windows form like the default form created in the project. The default form created in the project has designer.vb and resx file.
When I try to add new form via Project menu, I can't find any of the icons that resemble to the icon of the default form Form1.vb.
Please see the attached image for details.
You can do this two ways:
Add->new->new item. You see this:
Then you get this:
So, from above, you select Form (windows form)
but, since creating a new form is "common"
Then you can use what you choose:
right click, add->Forms (windows form)
that will then launch the SAME screen as above, but WITH the forms already selected - hardly saves you much effort and time - but either way, you can then type in the form name - BUT BE CAREFULL!!! - WHAT you type in, if you change the extension, you will wind up creating somthing VERY differnt.
So, ONLY edit the name part, so when I do above, and choose forms (windows form), then I get this:
But ONLY edit the text "form1" and do NOT change, or mess with the .vb that follows.
So, I can chose (set) the form name to MyCoolForm like this
So, don't put spaces in the name, and LEAVE alone the .vb part. That is also imporant.
Now, hit add,
and you should see this:
We have been using PDF file as a part of help docs in our vb.net desktop application. In PDF, we would traverse to the certain chapter in the PDF doc.
Now we have decided to use MadCap Flare as documentation tool. We have a menu item in vb.net form for documentation. On click of the link, we want to open the specific chapter of the Flare documentation.
You know managing content with single-source XML authoring is possible when using MapCad Flare (I'm not using Flare!). You can publish content to an increasing number of formats including HTML5, WebHelp, PDF, Word, XHTML, Clean XHTML, EPUB, DITA and more by MapCad Flare.
So, you may continue using PDF and the way connecting your vb.net desktop application help.
Using HTML based topics maybe another solution for your needs by creating Help for a form, a dialog or control with HTML files (See also: Help for controls with VB .NET).
Properties to display help (HTML file - local)
Activate the hlpProvider component hlpHtmlLocal and set the HelpNameSpace property of hlpHtmlLocal to the file name you want to work with.
We open a local HTML file with the dialog using the little button to the right.
The next step is to set the HelpNavigator property of a control (e.g. button) to a value of the HelpNavigator enumeration (see table below). Here we use Topic.
When the application is running click the HelpButton to enable "What's this .." Help. The cursor changes. Now click the button or press F1 when the button has focus. This will open the single HTML file in your browser.
It seems you can't use anchor names to jump to a specific part of your HTML file.
Properties to display help (HTML file - Server http://..)
Activate the hlpProvider component and set the HelpNameSpace property of hlpHtmlServer to the file name you want to work with. Here we use a http:// address of a single HTML file. If you provide the file on your company server, you don't have to update the help file with the customer.
The next step is to set the HelpNavigator property of a control (e.g. button) to a value of the HelpNavigator enumaration (see table below). Here we use Topic. Then we set the HelpKeyword on hlpHtmlSever property to e.g. "anchor3". Don't add a leading "#". Leave it empty if you want to open a HTML file without anchors. The Help Handles cmdControl2.Click Dim sHelpFile As String Dim sStartupPath As String '--- Initialize context-sensitive help --- Keyword property provides the key information to retrieve the help associated with the control.
When the application is running click the HelpButton to enable "What's this .." Help. The cursor changes. Now click the button or press F1 when the button has focus. This will open the single HTML file over the Internet in your browser.
I wondering if its possible to use Microsoft Word as a text editor in a VB.Net project?
My project currently uses a Rich Text Box to allow the user to right a report which is then saved and a report generated. I was wondering if i could switch to Word for better formatting and layout options, be it embedded in the actual form or in another form thats called (if that makes it easier to assign the control).
I have worked on opening Word itself via a button click but would like to have it incorporated in the project. All users that would actually use the program would have one of the more recent versions of word installed.
Any pointers to websites would be great as i'm constantly searching but not getting very far
Thanks
I have a picture library and added few fields to it. When i click add new item from picture library, the EditForm.aspx appears after uploading the picture. This form contains many fields of which I want to hide Title, Date Picture Taken, Description, and Keyword. In short the EditForm should contain only Name, Preview and the columns that I have added. Is it possible to hide the other columns? I want to perform this out of the box.
Several possibilities.
You can use SharePoint Designer to manipulate the NewForm, EditForm and DisplayForm. Edit the existing form, use CSS to set the out of the box HTML form to hidden, then add a new custom form to the page and remove the columns you don't want to see.
If you don't want to use these columns at all, just delete them in the Library settings
If you don't want to delete the columns, click the parent content type in the Library settings, then edit each column and set it to "hidden"

I found this solution to be really simple and effective. Very well documented and descriptive.
We have following requirement to be done via excel and VBA programming. Please check and let me know if it feasible to do so and if not what way would be best to do it.
There would be excel spreadsheet say excel 2007/2010 with 2 tabs.
1st tab contains normal excel data
In 2nd tab user can enter a particular value and then click on a button in same tab. Is it possibly to have a button in excel tab and can it raise events like windows/web applications?
Now if button can be kept in excel and it can raise button click event then on such an event we need to create xml files. Is it possible to create xml files adhering to schema using excel &/or VBA programming
You need to activate the developer tab (from backstage go to Options and check the visibility of this tab) to get access to normal windows controls, like buttons and drop-down lists etc. You can easily place those in Excel sheets and write event handlers: the controls support the full range of events, including OnClick, OnMouseEnter etc...
You can write custom text files directly from VBA, but you can't validate those. The usual way to do so is just to concatenate small XML blocks into a bigger file, so XML output is more like a normal text output. But it works fine and as long as you do not need to perform something really complicated it is also ok.
EDIT: You can easily add references to custom COM objects (.dll or .ocx) and use them directly in your VBA code. One very helpful suggestion (see the comment below) is to use the MS XML library.
To add a reference just open the code editor (Alt + F11) and then go to Options -> References. Most of the references you need will be already in the list and you just have to check them, but you can also add your own custom libraries by clicking on Browse.
