I'm trying to create a form with a lot of repeated components. I'm making a touch screen control system with a GUI in VB.net. I would like to make it so when a textbox is pressed a form pops up (form1.show()?). This form is basically a number pad. The user can press buttons (0-9) to get the desired integer to appear in a text box in the popup form. When the user presses an "Enter" button, the popup form returns the integer value that was entered to the initial textbox pressed.
I need to sort an array. I need the most repeated strings at the start and the least repeated at the end. Any easy way to do this? My brain is currently fried
Actually I am trying to make a datagridview in which there r 3 columns...payment_no, due_date and payment_date. In this DGV I want to show 5 rows (it depends on no of payments) of above 3 columns, something like this...
payment_no due_date payment_date 1 20.02.09 (filled by update query) 2 20.03.09 (filled by update query) 3 20.04.09 (filled by update query) and so on........
Im new to VB.net programming and I was wondering on how can I hardcode all of this components. What I'm trying to accomplish is that I want to create my own Binding Navigation along with other components hardcoded so that I can navigate through the DatagridView with my own buttons.. Here is a screenshot
I deleted a textbox on my login form and when I debug the startup (login) form still has the textbox that was deleted. I tried deleting the form and its components but still this form appears on start up Is. there any way that I can fix this?
I want to dynamically add some lables and progress bar on form and then set the values for it.
[Code]...
i'm setting on error on line where i'm setting the location of x and y. if i remove those lines it works but all the progress bar are shown at same location. Also i want to set the values of progress bar, i was trying this me.controls("Pbar1").value = 100 or PBar1.value = 100 but it doesn't work because in 1st case it doesn't know the control is pbar and in 2nd case it says PBAr1 doesn't exist and won't make the build.
I have a development system and two test systems. My development system is Windows 7 (64 bit). My two test systems are Windows XP (x86) and Windows 7 (x86). I have created a program on the development system mostly in VB.NET 2008 and deployed it. It looks nice on the development system and on my Windows XP system, but when executing the software on my Windows 7 (x86) system, all the form sizes and components somehow grow. To investigate the issue, I moved over the entire project and opened it on the Windows 7 (x86) system to find that the sizes have somehow changed in the designer there as well. I opened up the .Designer.vb files and the sizes there all seem correct. Then I go to the IDE and the sizes are larger than they should be. For example, I will set a form size to 532, 217 on my development PC then it will show up as 709, 267 on the test system. I tried putting in code on my form.load event to set the size to 532, 217 then re-deployed it, but again, it executes and the form is too large.
I have a form with about 50 controls on it. labels, check boxes, combo boxes. text boxes and so on. Now I have a image on the back ground of the form and have made the checkbox text with transparent back ground so the picture can show through. the problem is that it is so slow to load. I see each one appearing on the form one by one. I have tried this on multiple machines and it does it on all of them. I have tried making the checkboxes not transparent but it still is slow.
how can I allow the form to load completely before it displays it. This is the initial form that loads and shows up.
Is it possible to make a program with visual basic 2010 that does not use the actual form but instead only uses other components (e.g. Message Box) to form a complete program?
I have a lot of repetitive code that references components of my main form. I wanted to create a separate module (correct terminology?) for all this code to be contained. I cut the offending code and pasted it into my new module, changing each label reference, etc to form1.label.click
Form1 was then underlined and I get this message:Handles clause requires WithEvents variable defined in the containing type or one of its base types.I think I'm headed in the right direction, but what exactly am I looking for? Here is a sampling of the code that I would like to keep in a separate place other than Form1.vb:
I used the "Anchor" options to resize components when i maximize my form using the default system button and all works fine. But if at anytime i double click on the title bar to maximize/restore window it maximizes, but when it's to restore it won't became the original states, it comes like a big window not maximized.
The AreaOrigin is filled with lots of diffierent strings but a lot of them are repeated. What i need to do is distinct the strings but also show how many times they are repeated in descending order.
I want to get random numbers between 0 to 100..But i do not want the random number to be repeated.
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim objRand As New Random objRand.Next(0, 100) End Sub
Suppose first time random numb generated is 10..Next time if same random number is generated,den i want to get the other random number..
I've run into a bit of a roadblock trying to figure out how to programmatically not allow the same data in multiple comboboxes. I'm usnig VS2008 and I have 3 comboboxes on a form, all with the same data, say "apple", "orange", and "red". The comboboxes are nothing more than a user definable sorting method on which gets calculated first. When I use the .SelectedItemChanged event on any of these, I'll obviously be duplicating. Any idea on how I can program to automatically switch the combobox that is duplicated to the value that is missing? I don't want to hard code it as further down the road I will have up to 7 comboboxes. Below is what I started with coding. Not sure if it is the best way to go about it, but it works on 4 of the 6 combinations.
I am trying to populate a VB.net dropdown box which is repeated in a datagrid. Basically I have a bunch of images and the user needs to select from a dropdown listwhat colour the item is so that I can then save it in the database.
Dim DDLPlayColorList = New DropDownList DDLPlayColorList = dgImages.FindControl("DDLPlayColorList") Using oConn As New
However the Split() function cannot translate to a SQL equivalent, and so this can only be executed in-memory, which is excruciatingly slow by the time any number of records are involved.
The SQL to do this would be something like
WHERE Description LIKE '%word%word%word%'
And that's as far as I get - I can't work out how to get that SQL generated by LINQ to Entities. I tried the ugly hacky .Where(Function(x) x.Description.Contains("word%word%word") on the off chance, but I'm almost relieved that it doesn't work!
So although we have plenty of keys from our subscription, to minimize tracking and confusion we just want to use2 or them over and over as we install, test, extended test, wipe and reload. Eventually we would have to recycle any way. Much of this will be scripted /automated and we were wondering what kind of problems we will run into for the activation cycle (human intervention required, phone call, etc.) Mostly working on Win7 (all versions) but still need to do some Vista and even XP.
The known part is the [0] or [1] or whatever number in the brankets.the unknown part is the rest of the message.So if i have this string i want to cut it to smaller substrings that start with [ and end before the next [ .To make it more tough, sometimes, before the next [ there is another message that comes like: Jun 19 17:13:40 2012 timestamp And after that it continues with the next [
how to create a Auto repeated Mouse movement.I wanna create a Form, with a button "start 01" and "start 02",so if I click on "start 01" button, and i open my other applications, and once I hit the F1 button (on my keyboard) the mouse will auto move from point A to B, and it will keep on repeat until I hit the F12 button, then it will stop auto moving.and if I click on the "start 02" button, and II open my other applications, and once I hit F1 button (on my keyboard) the mouse will now move from D to E, and it will keep on repeating it until I hit the F12 button, then it will stop auto moving.
how can i do it so the same image doesnt get repeated more then once. so when two of the same images are already picked, it goes on to select a different image until there are pairs of everything. This is my code
