Weird String To Create Button Name Visible?

Jun 29, 2010

I have a graphical button named ba1(blue arrow 1), ba2, ba3, etc to ba8 which coincides with questions on a sig pad 1-Qmax(=8) so that the clinician can see which question the patient is answering at the time.I need this For statement to work but it is giving me syntax errors and nothing much else. I am guessing it doesn't like placing a string and integer together. I have tried turning the int into a str and it balks.[code].....

Button On Form - Visible To Invisible?

May 18, 2012

I understand the properties to change a button from visible to invisible, but I need to be able to have two buttons alternate visibility when the first button is clicked.It's for a game. The first button is to "Begin Game" and on open, the invisible button that sits over it is called "Begin Again" which I would like to only appear once the Begin Game button has already been clicked. This would then trigger the "Begin Game" to become invisible.

Create Screenshot With Visible CURSOR?

I have been searching for a screenshot example for the 2008 version that can show cursor, and thought it should be possible to upgrade this one. I suppose that means a lot of rewriting, and I am still not capable to comprehend all the code and what to rewrite it to, but maybe someone else is, and would like to try to upgrade this PERFECT code for the whole community (probably not just me who needs this)?

Populate Textboxes And Make Them Visible Once Button Clicked

Mar 10, 2011

I was looking for some better way of coding to populate all text boxes and make them visible once a button is clicked. I have a letter like format on a page with labels displaying address, name etc and it was recommended that on this page some of the information should be able to be edited. The idea I had was to keep the labels displaying the information but then when the edit details button is clicked the labels disappear, text boxes will appear and be populated with the same text as the label to allow the user to edit the details.

I seem to repeating lines of code but changing one thing each time on page load
Dim Sname As String = Request.QueryString("Name")
lblStuName.Text = Sname
tbStuName.Text = Sname
tbStuName.visible=false
[Code] .....

On edit button
tbStuName.visible=true
tbAddress.visible = true
etc..

On the save button
sqlStatement = "UPDATE StuTable SET Name = '" & lblStuName.Text & "', Address = '" & lblAddress.Text
My code seems very repetitive in many parts, I was looking for a better coding style to do this.

VS 2008 Button Set To Visible = False Causes Form To Not Open Properly

Jan 1, 2010

I have a form which won't open properly under certain circumstances if a particular Button is set to visible = false. Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

Build Failing When Adding A String, No Visible Errors

Mar 14, 2011

After adding a string to the program from the resources the build always fails, and removing the string and the code to load the string does not solve the problem, as the build still fails. We've been using multiple versions of the program since this started happening with the most updated one, and adding the string is what started the failure in building even though we added other elements (like an exit button) and other forms without it failing. With the one that started with the build failures we've tried it on all types of computers and it does not manage to build on any of them, even one's with a new installation of Visual Basic Express 2010.

The exact line added that apparently makes the build fail is:

PictureAndInfo.infoBox.Text = My.Resources.StegmeierBreweryString

And the string added to the Resources isn't anything unusal compared ot the rest we have but it is this is:

The Stegmaier Brewery business began in 1857 when Charles Stegmaier first set up a shop. Since then the Stegmaier business has grown greatly. The size of their operation has grown from the original shop to the large building pictured to the left (opened in 1863 and purchased from Stegmaier in 1978). The Stegmaier Brewery Company was purchased in 1974 by Lion, Inc. and Stegmaier Beer is still produced today by Lion, Inc. and remains a popular choice among consumers.

I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

Jumping Between Forms - Making A Form Visible And Not Visible

Jul 17, 2009

I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.

As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.

If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

Weird Value Returned When Using Len

VS 2008 Weird Text Box?

[Code]...

I don't know of any better way to have it handle each textbox, hence the long string.Anyway, these boxes are populated from a database and this code seems to work fine if there is already a number in the box. If the box is empty and I try incrementing it, I only get the actual "+" or "-" in the box and it locks my whole form out. Clicking other textboxes doesn't activate them, and my buttons press but do nothing. I can't even exit the program with the "X" in the upper right. As far as I can tell that's how to replicate it anyway.

IDE :: IDE Giving Weird Build Error

Oct 26, 2006

I just finished putting the first 6 datagrid controls on my form and i went to go test it and got this build error: Error 4 Value of type 'String' cannot be converted to 'System. Windows.Forms.DataGridViewTextBoxColumn'.C:SoftwareForm1.vb 1425 19..When the line generating the error is this Me.Name = "Form1".where it has the "Form1" portion underlined in blue.This is a weird error because that line was made by the IDE to say the name of the form and has nothing to do with 'System.Windows.Forms.DataGridViewTextBoxColumn'.I tried saving my progress and restarting the IDE with no luck..Now I cannot even access the form in designer mode,One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.The designer cannot process the code at line 1424: Me.Name = "Form1" The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified.
