Yes. I was reusing old code which allowed color images. I wasn't the original author, so I didn't change anything that I didn't think absolutely had to be changed, and I wasn't sure whether any of the other reused code implicitly assumed the specified format. Indeed, experimentation since you raised the issue showed that using other formats (including indexed and grayscale ones) does cause other problems.

In general, Windows (10) recommends against bit maps because they don't scale well. Use (font) icons and vector graphics. Segoe UI MDL2 assets can be overlayed, reversed and rotated. The .NET shape classess provide circles, polygons, etc.
In your case, I would try overlaying the outter problem area with an ellipse / circle (black stroke, transparent fill) for a quick fix.

Well, that was very interesting! Doing as you suggested does not solve the problem. If you use a sensible sized pen (fairly small), nothing visible happens, and the 'halo' looks just as before, though there is a suggestion of it disappearing at the points where the drawn circle overlaps the edges of the original image (the top, bottom, and two sides). If you use a thicker pen, it is more obvious that the 'halo' is gone at the overlapped edges, but it is just pushed out to the edge of the drawn circle over the rest of the rendered image - it still always appears where a 'transparent' pixel was adjacent to one of another color, whether that pixel was part of the original bitmap or subsequently drawn on the Graphic. Presumably, therefore, it is an artefact of the [Bitmap].MakeTransparent() Function, but I have no idea why it has not (as far as I can tell) been described before
Parenthetically, I now see that that function forces the Bitmap on which it is invoked to 32bppRgb mode, since that format has the alpha channel which it needs, so any attempt to use a different format would be pointless.

I think your problem is part of Windows Forms.
I do a lot of graphics in UWP and WPF and never have any issues I can't overcome.
e.g. WPF and snap to pixels:
Quote: You can set this property to true on your root element to enable pixel snap rendering throughout the UI. For devices operating at greater than 96 dots per inch (dpi), pixel snap rendering can minimize anti-aliasing visual artifacts in the vicinity of single-unit solid lines.

I want to pass PointF as optional Parameter. But I am finding it difficult to assign default value for PointF.
I can't assign Nothing. If I do it becomes (0,0) which can be working value hence can't be used as a unique default value.
I am not able to assign any other value. I tried (Optional P1 As PointF = New PointF(-100, -100) but it does not work.
Public MyFunc(Optional P1 As PointF = ????)
Please help.

Use a nullable value type:
Nullable Value Types - Visual Basic | Microsoft Docs[^]
Public Function MyFunc(Optional P1 As PointF? = Nothing) Or:
Public Function MyFunc(Optional P1 As Nullable(Of PointF) = Nothing)

Hello everybody,
Maybe this is not the correct place, but the programs (web service) it is in vb scripts.
First i don not nothing about VBS, but we have an old WS in VB.
This is how its works:
http://..../ws?cmd=country
Then the scripts read the action, and call a method (just a query and return a JSON).
The problem: if we need to pass an specific country: How do we do it in the http and how to read the parameter in the code, because the script only recives: country, cities, etc and return the whole data.
Thanks

There is no way anyone can answer your question based on the information provided. We have no idea what your code is doing, so how are we supposed to know what parameters it accepts, or how you can pass them?
Talk to the person who wrote the service, or consult the documentation.

That is correct, here is part of the code:
<%@ Language = "VBScript" %>
<% Option Explicit %>
<%
sAction = Request.QueryString("cmd") 'This received the action: 'http://.../ws/get.asp?cmd=Sucursales': Sucursale, and with a Select Case execute the method
If sAction & "x" = "x" Then sAction = getFormField("cmd", 1)
If sAction & "x" <> "x" Then
...
Select Case UCase(sAction)
Case "SUCURSALES"
Call getSucursalesJSON()
Case "AGENCIAS"
...
Sub getSucursalesJSON()
Dim sSqlWrk, rswrk
sSqlWrk = "SELECT LTRIM(RTRIM(a.[AGE_CODIGO])) AS 'AGE_CODIGO', UPPER(LTRIM(RTRIM(a.[AGE_DESCRIPCION]))) AS 'AGE_DESCRIPCION'"
sSqlWrk = sSqlWrk & " FROM [" & xDb_CatalogOpe_Str & "].[dbo].[SUCURSALES_X_AGENCIAS] AS x WITH (NOLOCK)"
sSqlWrk = sSqlWrk & " INNER JOIN [" & xDb_CatalogOpe_Str & "].[dbo].[SUCURSALES] AS s WITH (NOLOCK)"
sSqlWrk = sSqlWrk & " ON x.[SUC_CODIGO] = s.[SUC_CODIGO]"
sSqlWrk = sSqlWrk & " AND x.[COM_CODIGO] = s.[COM_CODIGO]"
sSqlWrk = sSqlWrk & " INNER JOIN [" & xDb_CatalogOpe_Str & "].[dbo].[AGENCIAS] AS a WITH (NOLOCK)"
sSqlWrk = sSqlWrk & " ON x.[AGE_CODIGO] = a.[AGE_CODIGO]"
sSqlWrk = sSqlWrk & " WHERE (x.[COM_CODIGO] = 1)"
sSqlWrk = sSqlWrk & " AND (x.[SXA_ESTADO] = 'A')"
sSqlWrk = sSqlWrk & " AND (x.[SXA_TIPO] = 'S')"
sSqlWrk = sSqlWrk & " AND (x.[SXA_REGISTRO_WEB] = 'S')"
sSqlWrk = sSqlWrk & " AND (s.[SUC_ESTADO] = 'A')"
sSqlWrk = sSqlWrk & " AND (a.[AGE_ESTADO] = 'A')"
sSqlWrk = sSqlWrk & " ORDER BY x.[SXA_ORDENAR_WEB], a.[AGE_DESCRIPCION]"
Set rswrk = conn.Execute(sSqlWrk)
oJSON.LoadRecordset rswrk
Set rswrk = Nothing
oJSON.Write()
End Sub
If we need to call the WS:
'http://.../ws/get.asp?cmd=Sucursales' This return the whole table,
This is a very old code, but now we can not change it, so we need to pass:
'https://www.eps-int.com/ws/get.asp?cmd=agencias' + plus an specifc agencias
PS: Nobody knows who made this code. It was more than 8 years ago

You can read query-string parameters by accessing the Request.QueryString collection - eg:
Dim sAgencia
sAgencia = Request.QueryString("agencia") You can test whether a value was passed by calling Len:
If Len(sAgencia) <> 0 Then
...
End If If a value is passed, you would need to add an additional filter to your query. However, you need to pass the value as a parameter to avoid a SQL Injection[^] vulnerability. This will complicate your code slightly - for example:
Sub getSucursalesJSON()
Dim sSqlWrk, rswrk, cmd
Dim sAgencia, pAgencia
Set cmd = Server.CreateObject("ADODB.Command")
Set cmd.ActiveConnection = conn
cmd.CommandType = adCmdText
sSqlWrk = "SELECT ..."
sSqlWrk = sSqlWrk & " FROM ..."
sSqlWrk = sSqlWrk & " WHERE ..."
sSqlWrk = sSqlWrk & " And ..."
sAgencia = Request.QueryString("agencia")
If Len(sAgencia) <> 0 Then
Set pAgencia = cmd.CreateParameter("agencia", adVarChar, adParamInput, 100, sAgencia)
cmd.Parameters.Append pAgencia
sSqlWrk = sSqlWrk & " And (x.agencia = ?)"
End If
sSqlWrk = sSqlWrk & " ORDER BY ..."
cmd.CommandText = sSqlWrk
Set rswrk = cmd.Execute()
oJSON.LoadRecordset rswrk
Set rswrk = Nothing
Set pAgencia = Nothing
Set cmd = Nothing
oJSON.Write()
End Sub To reference the ADODB constants, you will need to make sure the file includes the adovbs.inc directive towards the top:

Thanks a lot,
That is.
Thanks a lot again
So, to call the method from the http the parameters are pass using the normal rules to pass it?
|
|
|
|
|
Yes, you'd just pass them in the query string, remembering to URL-encode them if necessary.

Sorry: I can not make it works
Here a few word and how it works
First, we call the WS:http://..../wstest/get.asp?cmd=Agencias
In the code:
'Read the Request.QueryString("cmd")
sAction = Request.QueryString("cmd")
'Checked the action, action do not recives any param at all
'Then calls, depends of the action, a function
Select Case UCase(sAction)
Case "SUCURSALES"
Call getAgenciasJSON()
Case "CEDULA"
Call getCedulaJSON()
Case "RNC"
Call getRNCJSON()
Case Else
sErrorKey = "invalid_key_value"
sErrorMessage = getDictItem("Common.InvalidKeyValue")
Call SetUpJSONfail()
End Select
'This a function. All functions are like this
Sub getAgenciasJSON()
Dim sSqlWrk, rswrk
sSqlWrk = "SELECT * FROM [" & xDb_Catalog_Str & "].[dbo].[SUC_MAESTRA] as x with (nolock)"
sSqlWrk = sSqlWrk & " WHERE (x.[SUC_ESTADO] = 'A')"
sSqlWrk = sSqlWrk & " ORDER BY x.[SUC_DESCRIPCION]"
Set rswrk = conn.Execute(sSqlWrk)
oJSON.LoadRecordset rswrk
Set rswrk = Nothing
oJSON.Write()
End Sub
'This is the new function, which of course needs a param,
'The question is: How can i read o pass the param using: http://..../wstest/get.asp?cmd=cedula=784512422
' because cedula need a param. How can i read the param using sAction = Request.QueryString("cmd")?
'
Sub getCedulaJSON()'
Dim sSqlWrk, rswrk, sCedula
'How can i get the param cedula and it value in order to make the select
sCedula = Request.QueryString("cedula")
sSqlWrk = "SELECT nombres, apellido1, apellido2 from cedulados where trim(mun_ced) + trim(seq_ced) + trim(ver_ced) = '" + sCedula + "'"
Set rswrk = conn2.Execute(sSqlWrk)
oJSON.LoadRecordset rswrk
Set rswrk = Nothing
oJSON.Write()
End Sub
|
|
|
|
|
It is not simple to parse something like http://..../wstest/get.asp?cmd=cedula=784512422 but it is easy to parse something like http://..../wstest/get.asp?cmd=cedula&value=784512422. Just use Request.QueryString() to get the value. Start your select case as before e.g.
sAction = Request.QueryString("cmd")
Select Case UCase(sAction)
Case "SUCURSALES"
Call getAgenciasJSON()
Case "CEDULA"
Call getCedulaJSON()
Case "RNC"
Call getRNCJSON()
Case Else
sErrorKey = "invalid_key_value"
sErrorMessage = getDictItem("Common.InvalidKeyValue")
Call SetUpJSONfail()
End Selectand then check for the value in the subroutine. Viz:
Sub getCedulaJSON()
Dim sSqlWrk, rswrk, sCedulaValue
sCedulaValue = Request.QueryString("value")
sSqlWrk = "SELECT nombres, apellido1, apellido2 from cedulados where trim(mun_ced) + trim(seq_ced) + trim(ver_ced) = '" + sCedulaValue + "'"
Set rswrk = conn2.Execute(sSqlWrk)
oJSON.LoadRecordset rswrk
Set rswrk = Nothing
oJSON.Write()
End Sub
----------------------------------------------------------------------------------
Not an answer to your latest question but ...
I noticed that on 29 July you had code starting with
Select Case UCase(sAction)
Case "SUCURSALES"
Call getSucursalesJSON()
Case "AGENCIAS" and now you have
Select Case UCase(sAction)
Case "SUCURSALES"
Call getAgenciasJSON() I suspect that you have just mis-copy/pasted and actually want
Select Case UCase(sAction)
Case "SUCURSALES"
Call getSucursalesJSON()
Case "AGENCIAS"
Call getAgenciasJSON()

My motherboard finally died, so I figured I would upgrade my PC. I am running windows 10, which I was running on my old system. I tried to re-install an older version of Office but found out that windows 10 does not support the older versions, so I upgraded to Office 2019.
I have a number of Access applications, that are now missing ActiveX controls I use on a number of forms. I can not find a replacement for the worksheet control (OWC11), how have other people been solving this?
There is an ActiveX calendar control listed (Calendar Control 12.0) but when I select it I get a OLE server is not register error, but I have no idea where to find the control.
Any help with upgrading would be appreciated.

I would install a "supported" OS on a virtual machine (VMBox; Hypervisor) and rebuild there. I have an XP box for my car's service manual app because it's that old.

Hi Gerry,
Thanks that is a good idea, but I have Win 10 Home so I can't run the hypervisor, but I do have a copy of VM Ware Workstation and that can get me over the hump.
Still looking for the replacement controls while I refactor the code to another platform.

Most people I know are avoiding the ActiveX controls entirely. I came across this a few years back - MS Access - Calendar/Date Picker Control | DEVelopers HUT[^]
I think we went for the UtterAccess one in the end but it was at a different job and my memory isn't the best. It would have been Win7 then too but by all accounts Pete has been keeping it up to date - the comments seem to suggest that it is fine on Win10

My old PC has been flagged by MS as incapable of loading Windows updates for 18 months due to its antiquity so I, too, have migrated my old (20+ years) MS-Access apps (which get a lot of use) to a new PC with Office 2019 but the new PC is not yet my main one. As a result of your question, I have checked one of my old apps. For dates, I have Date/Time fields in the underlying tables and display using TextBoxes. I can confirm that even in O2019 there is still a date picker displayed when these fields have focus / are clicked on. You may be able to use the same technique (Date/Time field shown as a TextBox) as an alternative way of selecting dates if you cannot get your ActiveX control to work.
Re other responses: Yes, I did get the memo to move away from MS-Access. But, as a single user, I have never had any problems and follow the "If it ain't broke, don't fix" principle. Plus, I have yet to find any other environment that enables you to have a database, code, forms etc under a single roof that can be changed on the fly if needed. I would like to move off MS-Access as it has only been supported in Pro versions of Office since 2003, but it has served me well since it first came out. Some of my apps have been on MS-Access 1.0 / 1.1 / 2.0 / 97 / 2003 / 2007 / 2016 / 2019 with only minimal changes (even the move from AccessBasic to VBA only really affected a change in the RecordSet class and a few error codes).

I agree. I use the database for my own project and over the years the numbers of lines of code has grown to an impressive number.
I will give the text box idea a shot. I use the unbound textbox to stop my code from running at a certain time.

I was able to find the OWC11 installer on the CNET download page. I installed it and it has been working well. I did have to recreate the controls on my forms but at least things are working again.
